20- Telephony Basics

we deploy voices and application folks it's that simple it's that simple it's we didn't know anything about PBX is trust me I was at Cisco when I came to Cisco the other there was nobody here it could talk talk I mean let me give you an example I worked I worked with some brilliant essays data guys I worked with people who had multiple CC IES and all the stat in the other and every time they go to a customer's start talking this the first thing they talk about is the reliability and reliability of this box my networks down a lot more than my voice I don't know if I could do that so I'm worried about that I said well we can engineer and all this that and the other and then they finally come to what they were talking about five nines reliability what's five nines reliability five minutes a year five minutes of downtime of year Wow are we good at that on the data side no no we're not good at down basic I was a operations manager I never had to report my data side of availability because it's kind of gray if you take your laptop and you boot up on a network and get an IP address through DHCP is the network up I think the networks up but if you click on an icon and try to go to a web server or to a server and the server's not there is that a network issue or application issue so it's kind of gray was this box reliable absolutely but this is a this is a really a bad bad thing to actually point out for me because as soon as you did that you opened up the whole world to me let's figure out how we come out with that does anybody know how you come up with this number I mean you think number of minutes divided by number of downtime minutes or uptime minutes in a period whatever it is that's what you get but there's a lot of other things that go involved here let's say it one of these cards just one of these cards in here has 24 phones attached to it I have 600 stations on my PBX 600 my line cards have 24 phones on each one if that line card goes out do I count that as system downtime do you where's that where's the tipping point where is the point where you say yes it's down and no it's not what percentage I'll tell you what the industry is ended up at you have to have 30% of all the phone stations down at any one time for this to be called system downtime so that means that I can come in I could have a really bad day driving into work had a flat it's gonna be late so I've changed my flat and I've drove down the road too fast and the cop pulled me over then my wife called me up and told me that you know she's leaving me or whatever it is and I walk into work and I'm just mad as I can be and I walk by and I say you know what I don't care and I just ripped the card out and twenty four phones just went dead is that system downtime no it's not if I have 600 stations how many do I have to turn to pull cards do I have to pull out before it becomes system downtime 30 percent of 600 is how many 180 I couldn't do some real poll and I might calm down before that that's how they reported that but you know the average person at Cisco didn't know that so man they were sitting there oh my god we got to duel this - all that other cries price goes up it's exactly what happened Cisco didn't know what they were doing at that time I'm telling you that we were being played so bad a lot so many count teams were being played by the the competition they were calling they weren't calling IP telephony they were calling it voice over IP even to this day people call it voice over IP it's not voice over IP that's voice over IP this is IV to laminate voice is an application that's what it is but we must have done something right because in 2001 start getting some customers who wanted to start looking at this 2002 was a really good year for us I mean downturn economy and all that we still sold a lot of this we had customers who were looking at we had added features we got it got to where we could talk and do this and again in 2000 number one in the world was Nortel Networks number one in the enterprise was a vaya vaya what in 2008 2009 who's number one Cisco in a very very short period of time we actually came out and changed the world with this on what what happened the IP office yeah that low at that low end I mean we've never played there very well I think we do I think we do I think the business Edition 6000 is a great answer to that to be honest with you that Business Edition 6000 yeah it's it's coming at huh excuse me oh yeah absolutely but that you've got to elevate the discussion you've got to just not talk about and you have to think at the time is working in our favor because guess what I and I don't want to go too far right now but I'll tell you this much right now I've got customers telling me today they don't want voicemail they will not they are not going to do voicemail again do you think Emily uses voicemail I promise you right now if I picked up my phone and I called Emily's voice but she's had her phone for a year and a half she's never answered a voicemail she's never set it up she's never set it up so guess what the game is changing here the game is saying we have to accelerate to change what is available to these people yeah there's still gonna be people who want it people like me people like my wife whatever but guess what we're starting we're starting to worry about these new people coming in you know huh yeah yeah yeah so so it's there's some changes in that I'm not going to say that we that we don't have issues in certain markets and everything but I'm telling you we did take that we were the ones who drove this and and we need to use that with customers who may not understand what role Cisco played in here not because we're the nut not for anything else but we have delivered consistently and driven this market and driven this market that makes sense so let's just talk about how a solution might look from a Cisco perspective yes well they've they're all moving to an IP based solution right all those those big iron is going away right no we don't well we'll get into that when we talk about HCS because we're only going to look at it from a hosted model we'll talk about that in just a second of a few minutes this makes sense though so far this is what we did so let's just talk about how our solution may look on a network and it's easy to sit here's the easiest way from and again I'm not smart at all I have to simplify things I look at this in three phases I'm looking at services I'm looking at clients and I'm looking at infrastructure that's the three things I talk to customers about around Cisco solution services some kind of service on a network and application what kind of clients I want to address with that and what kind of infrastructure needs those clients are going to have so let's just look at this so in a typical solution we'll have a switch POV we'll have a client called an IP phone and again IP phones are another thing that may be passing away phones the actual physical phone people don't want those anymore now we still are going to sell those for several years but it's going to start declining significantly I think as these new people come through you used to be if you had a phone you had job security that's the way I used to view it you don't have that anymore there's no job security and they give you a phone baby right so this phone this IP phone is a client but what about on a PC could I put a client on a PC absolutely our client is jabber our jabber client its software we've had soft phones for many many years many many years we've got jabber as a client so that's the client and we're just going to stick with voice right now but we're going to add to this in a few minutes what's the service that that they need what's the service it's called Communications Manager Communications Manager is our service that this needs here's what happens you plug this phone in it goes out and gets an IP address let's say ten ten ten six it's got a MAC address address that makes it unique and I say MAC address a it registers with communications manager how do you put that phone in that Communications Manager you put its MAC address in there you put it in his MAC address he's got a table it's just a database that's all it is it's just a database in that database it says the MAC address you know it could be we could dedicate an extension to it or do extension mobility where people can log in whatever it is the features for that for that phone and by the way when it comes in the Communications Manager it actually tells communications manager it's IP address wherever it's sitting at today so it actually gives information back to communications manager because you can move these phones anywhere you want so if I plug a phone in is 10 10 10 9 and then I get 10 10 6 or whatever it is it's going to tell communications manager where it's at this is really important if this is let's say this is a MAC address be well MAC address be this extension whatever extent you want give it all its features and it tells us it's IP address let's say its IP address is 11 11 11 9 this guy's 10 10 10 6 all communications manager is is a resource for people to say I'm trying to find somebody that's all is so if I pick up this phone I go off-hook it sends one packet from this client to this server one packet one packet and it starts a call detail record a record of saying here's the tracking of this call it's a log that this call is happening and it sends back one packet and says play dial tone dot wave and that person's ears so they know that it's working that's all it does then you dial the number let's say this person's extension is 3200 your extension is three thousand you dial 3 2 0 0 he goes into his database that finds the extension 30 to hunt and finds the IP address of it says oh he's calling this client over here is that client on the phone what if they're on the phone what do I do with it what happens when it rings me does I have a second line appearance all these different things you goes through a list of those if you're not on the phone it says ok I'm going to do a setup between this IP address on this IP address let's see if they answer Communications Manager tells this phone where how do you know somebody's calling you phone rings well he has to use the MAC address here you have to use the MAC address because that's the only thing that differentiates all the devices on a network your IP address doesn't have to put the name communications manager absolutely yeah and you can do that with a bulk tool you can import it yes well you can actually you can actually get a a spreadsheet and just dump it in there like if you ordered a bunch of phones or whatever or you could actually do self-service give the customer and say I guess what if you got a MAC address on your PC here's what it is sending in an email you go in there put it in yes the MAC addresses yeah exactly that's what ties that makes that Hardware unique in theory right yeah but it's all based on the MAC address the IP address is going to change so now I've got this communications manager tells this phone to ring whether it's a hard phone or a soft phone it's going to ring in some way shape it's going to make a noise and somebody's gonna answer it in some way and then as soon as you answer he's going to say this guy talked to this guy to RTP streams one going this way one going this way do you talk to you communications managers are set some weights it's not going through communications manager it's now a client to client discussion communications manager is out of the way when you hang up they go back and say we killed that call I stopped my call detail records so now I can report on it I mean the clients go back to normal that's how it works that's how it works not rocket science not rocket science what if I want to call outside I always want to do that to the router this is now a voice gateway going to the PSTN if I want to call my wife see what's going on with her little mean dog see what she's chewed up lately she always choose my stuff up she doesn't shoot anybody stuff up but mine I had a nice hat a hat I used to I loved had that hat for two years I left it laying down close and that dog choose my hat up right the two days where I left it's the closest that dog came of getting killed I say shoot my hat I want to call my wife what do I do same thing with the PBX I have a dial plant here I pick up the phone it sends dial tone starts to call detail record for me i dial nine the I have a routing table here it says oh they're calling outside what's the visa the closest way to get to that go out this router this router is an IP end point it says push out these numbers to the PSTN so that he can call his wife when this guy sets up that call from this IP endpoint to this IP endpoint he sets it up he just says hey router IP talk to this phone go set up a call and send this out yes whoa whoa we do have Wi-Fi phones yes yes and again they can be Wi-Fi out here as well they're on a network you're on a network oh now everything's a wave all on our phones everything is dial tone don't wave ringtone don't wave busy ring back that wave all those are WAV files on that phone that's more of a PC that phone is more of a PC than it is a phone it's uh it's on a MedPro card in it is that what's on a MedPro card it's a card and on a gateway or in a in something yeah it's still in a card yeah still on the card there yeah even an IP communications yeah and and that's what I tell customers you know what what and again our competition via the traditional competition they had to address this right so they did some really cool things I mean they took their CPU out and put it as a server they took some of these cards out and put it in a media gateway and all this that and the other they did some things but here's the problem with them they had a lot of the stuff to drive with them that was it wasn't easy to adapt that's the problem Cisco took you to the place they want to go day one day one that was the thing how are they going to get first of all they had to pull this out put a card in here and through the server up there and then they had to say okay then we have to take this bed pro card and put it out here it's you know it's a 17 step process for dial tone still with the Avaya solution with this still using a med pro Cardinal that which could be oversubscribed so then this again call detail record I'm talking to my wife what'd I do wrong what the dog doo dah dah dah dah and then as soon as we hang up there's the normal color codes down to call detail record do not make this complicated because it's not it's client server the server is a resource for everything I need to do that's all he is he's like a phone directory remember phone memory when we used to get phone books we still get him and nobody used him I don't know why you would use them you know I don't know why they still you still yeah I don't you know I can't tell you the last time the last time I used a phonebook I had a pellet gun I was showing my I took my girls out and I was letting him shoot a pellet gun and the thickest books I could find were two the pellets wouldn't go through so I took him out there because it's cheaper to shoot a pellet gun that is anything right so that's what I was doing absolutely no no no I this is good in the end is that well our deployment is actually a client-server application that Microsoft could emulate right but let's think historically do you think Microsoft could have went in and replaced this today could they replace this absolutely not they have a link phone you have a phone system but is it as robust and fully operational as ours yet not yet oh absolutely absolutely I mean don't ever don't ever underestimate your competition and Microsoft is graded doing things they're not fast but they're they'll get it they'll eventually get there and you can't ignore the elephant in the room but again I'm going historically through what we did and how we've done it this is mm this is 2001 did Microsoft have an answer for this in 2001 absolutely not absolutely not Danny even thought oh yeah we're probably well let me just give you some numbers and and again your theater is a little different you're in Australia hell you guys have sold more people he acts as the IP telephony down there you're really good at it we've had that discussion the other night Australian there's a high higher attach rate of collaboration sales in Australia than anywhere in the you anywhere in the world anywhere in the world so they're really good at doing this they're really good at doing this in North America North America 50% of all over 50% closer to 60% today all sales are I pee based are IP based solutions probably 40% of that Cisco yeah yeah and again very you know we've got in the low end we've got you know people who are still you know a lot of competition on the low end and all this but probably there's still a lot of opportunity there is not 50% saturation of IP worldwide in some countries absolutely in some countries individual countries are you talking about I think you have to be careful with those numbers though you have to be careful with those numbers if I take this out and hook it up here and I put one IP car at one IP phone on the network it's IP how many and I could have I've gone to customers who've had these solutions and they've got 25 IP phones they're counted as the IP solution but they've got 500 other people using traditional phones yeah so you have to be careful I've seen those numbers in some km out saying it specifically for you but I'm just saying be careful with those numbers it goes by customer by customer basis really doesn't and you kind of have to look at that because I've went in and customers told me I'm doing IP telephony oh can I see how it works and what you've got and all this that in the other he said they've got 20 little 25 IP phones and they've got five over 560 other phones out there and their third consider themselves IP telephony so you have to kind of look at those numbers but the again the the saturation you know in in North America we're over 50 close to 60 percent saturated of IP so so again the voice gateway here is is apart again we're going back to what we have server switches clients routers what if I wanted to cut what if I wanted to take this across a LAN put a router out here make it a voice gateway put a switch out here and I wanted to put an IP phone out here think about it in my old drawing I had a PBX or a key system at every site now I'm leveraging the infrastructure out there now I could have this phone this client register with that server over there without having to put a PBX out here right so this client I put it in my database with all the things I need and it's over here when I let's say it's extension 4000 I my phone and I'm calling my friend i dial 4000 this guy says oh it's this IP endpoint talking to this IP endpoint now now we have choices we have choices I have a couple of ways to go I could send that call across the PSTN or I could send it across my LAN just like I had when I had the two different networks and I had linked them up in this case this is home this is where it likes to go now built into our IP phones and our cell phones are a way to take advantage or to take into consideration the limitation of the wind remember LAN LAN land remember that diagram I showed you I've got a little limited bandwidth here voice when we encapsulate voice on a network the payload is 64 K to convert one voice call to data 64 K when I wrap that up in IP and and put it in a frame and everything it ends up being just south of a hundred K for a phone call in a land environment that's nothing that's nothing but maybe if I've only got two mega bandwidth that's a significant part of that in all of our phones we actually put another codec code or decoder in our phones and in our cell phones for low bitrate it converts voice to 8k and when I wrap that up it's about 25 K for phones for phone calls wouldn't that be better to send across the land yeah so when communications manager decides that he's going to send this phone call first he asks this router can I send a phone call across the land why would we want to ask the router that exactly because the router controls that bridge right he's the only one that knows and this is going to be more and more and more important call admissions and control why haven't we just talked about everybody's want to make all these video calls now and all this that and the other there might be a lot of crap going across there that that communication measures might even not know about so we've got to let the router decide the best use of the so there's routing there's protocols for this router to say yes you can send that call across here if he decides to send the call this way across here the communications manager tells the end point use that low bitrate codec you use your low bitrate codec so we don't use as much bandwidth as we have to do the minimal amount and then we tag it up and it and it works now yes sir yes yes yes there's routing protocols for that there's protocols of that router that communications now you can just set in communications manager the old way is you could say communications marriage you can send six calls across there and that's it but but in today's world there's going to be so much more going on across there we want the router to be able to determine that it's there's about four different routing protocols that will do this for you oh thank you how big can we have so initially our communications manager you know we've grown it how many devices phone devices kit or video devices can be put on one call manager solution one call my uh communications man how many thousands yes 40,000 40,000 why limit because of the actual servers and the way we do this and I'll get into that a second there we have that's called a cluster and we'll talk about clustering in just a second but cisco has duck and against this goes a very good engineering company cisco has documentation that says if it can show a customer how they can take that's that one solution is called a cluster once was how you can take a hundred of these and work them all in one IP solution so you could have potentially four million phones on the same network and cisco will support it four million oh absolutely we have multiple clusters we'll have clusters you're in India so we'll probably have a couple of clusters in India we have some out here we have an RTP and all this but we have documentation that shows that we can take four million phones and put them on one network and support it and it will work yeah now let's talk about that cluster thing the first communications manager that you configure is called the the publisher the publisher it owns the database that database it owns it I want to have redundancy in this right so the second communications manager is called a subscriber and it gets its database from the publisher when you boot that thing up and give it up and you say your communications manager he's gonna ask you a question am i a publisher or subscriber the first one you tell him he's the publisher and he says oh I get to own the database I own the database I can do readwrite access I can do it all it's mine the second one he says a my publishers subscriber he says you say you're a subscriber to the next question where's my publisher where's my publisher why do we want to do that for the integrity of the database the integrity of the database well early on it was a physical entity all of our servers virtualized so these are virtual servers so the database is living on a array somewhere these servers are just accessing the publishers owning it and distributing it as he needs to virtual software they come in CDs running on a UCS you see on UCS whatever you want to run it on yeah they could be standalone servers if you want and you can virtualize those to see series if you really want to you could take one C series and make it one one making either and that's stupid but but yeah these are just servers these are servers there's software this is all an application and they can be virtualized this makes sense makes sense all right so the publisher owns the database the subscribers use the database and I can have these subscribers to subscribe health how close could these subdue these subscribers have to be in the same box do they have to be we're close can they be or how far away can they be they the requirement is is 80 milliseconds round-trip time on a network between these two let me give you an example of that North America is a pretty big continent I mean it's pretty big for me man when you fly across it seems like forever but some I was working up in with Telus in Canada and then we came up to this we were talking about this they said they could go from Halifax Nova Scotia which is the far end of this continent and guarantee you 80 milliseconds round-trip time with the bandwidth requirements that we have all the way to Calgary to Calgary three-quarters of the way over three-quarters the way across our continent so I could have part of my voice now one subscriber in Calgary and my publisher in Halifax that's how far away these could be they would guarantee the services so it means what this is an application folks this is an application that's all it is cisco changed the way we that we have to think about this it's got to be on the network and this is this is called a cluster this is called a cluster a cluster is defined as two or more communication managers using the same database one of them will be a publisher and the rest of them will be a subscriber you could have up to 20 servers in the cluster 20 servers and yes it's by the the server's themselves yeah now Cisco has changed its licensing model in order to download this software what can you have to buy in order to download this Communications Manager software what do you have to buy no I'm just saying just to download this and use it a license for the users all you have to do is buy the license for the users and you can download the software for the servers and if you've got your own servers you download and put it on your under servers so if you've already in stuff if you already got a UCS installation somebody's already bought UCS and they have some enough server capacity there they could buy 20 you know 50 licenses and put the clients out here done they only have to be phones they just have to be software and then you can download this Communications Manager and our present server and run them used to not be that way but this makes it much more easy to get this out there and and and get customers using it really does yes well it's is it VM it's it's VMware and VM no no no no no on this the C series when we it has to be C series but it can be virtualized but it could be in a UCS and it doesn't have to be dedicated that server has to be all communications management yeah absolutely absolutely you have to run Linna it's running on Linux right so you're going to have to create a virtual machine so you're going to have VMware to create a virtual machine it's going to have to have so many CPUs and all this and again the reference guide that you're talking about did you look at how many pages it was 1200 pages 1200 pages so if you want to go to sleep for the rest of your life just print that out there besides your bed table you read a half a page you go to sleep at night that'll take you for the rest of your life you know you can buy different servers like I will I be em servers and everything can be but again we would rather do the C Series if you want to do a separate service yes sir manager content communications Maps you know they talk to and enable X number of phones based on those licenses and tell the phone now back one well the licenses go into communications manager right the licenses are in communications management switch that disabled well you have to you have to put the well there's there's a couple of ways around that you could actually license all these you can license communications manager and actually say guess what we've got 500 licenses the first 500 users who come to you I want you to record their MAC addresses and hand them out IP addresses we can even let our phone numbers we can even let people choose their own phone numbers if we want to yeah so it's easier to deploy this stuff than you think services probably not I'll tell you this I would always like to have services there in my first week yeah yes ma'am you have a question yeah oh you're definitely going to need some kind of service so it's update a one through seven support absolutely and people are used to that they were used to that yes sir inside the organization's it's it's an essence they have thrown voice over to the data guys and they own it they own it I mean and and what they've done is they've kept the voice guys because and they almost become specialists inside of there but yeah like you don't have the phone technicians running around moving phones and everything but your senior guys are still there because you know you still have to talk to the PSTN people you still have to worry about Dyle plans and all this that in the other which are totally different than the traditional guys have had so you may have a little specialist or whatever they probably don't more earmark them specialists they just probably just do a special job yeah so but they you don't see telecom and datacom now it's all day to come it's all dated now I've got right before a break right before a break I always want to do this before break or something what happens now here's where Cisco knows networking and this is where cisco has its strengths and i'm going to go back to to 2000 2001 when we were first selling this against our competition and again this hasn't changed really much except the protocols that we use we back then we use sccp as the protocol that ran across the network today we use sip that's the only difference in how any of this works since 2001 that's the only difference is the protocol that the clients are using cos sip is more of a standard base client and sccp was not as efficient as sip once we got our own proprietary version of it like everybody has but what happens when the weighing goes down oh say what okay so I have a client that can't see his server think about it on this side of the here's my server there's my client I have no data path to get there excuse me yeah but maybe got a sir you yeah you you you have to put a server out there what's a bit of server - branch yeah what just think about this this just think about if you are have not got connection back to your email server let's say you're at your house your internet goes down you open the Outlook or whatever mail clients you're using to connect to either Cisco's mail or your internet service providers May or whatever if you can't get there what happens that client is useless right it's client without a server it sets that sorry goes well I'd love to be able to give you your mail but can't do it this is early on back when I was had a lot more hair in a hand now we would put communications manager here or we'd put it out here and test it with customers and move it there but we wouldn't put IP clients here why because we knew Wan's go down and we were not going to risk our customers business on that very very quickly took less than three and a half months Cisco said guess what we've got what devices do we have out here that Cisco that might be able to help us all right they created a version of software that goes on the router called s r st SRS T stands for survivable remote site telephony and you know what this was the biggest different one of the biggest differentiators and proof that the network does matter and our networking devices can do more and I'm going to show you a you know pictures are better than words and went from a volume up here oh I gotta get my cable so srst let me turn the volume up as far as I'm good and I'll put my PC up here so maybe it'll the sound will go a little bit better they didn't give me speakers here but we've had this since 2001 and I'll show it to you so communications manager at headquarters here IP when here branch router branch routers connecting to the PSTN at any city location whatever keep lives go from the client back to the server if I want to call my friend over here and say hey let's go to lunch today let's go have a Italian I pick up the phone communications manager says it's this IP this MAC address sets up with this MAC address you want to talk these two IP addresses talk uses real time protocol communications manager is not in the flow of the traffic if we want to go make reservations to have pizza because everybody likes pizza we dial out go out our local gateway use the DSP resources in the router if we want to call our friend here at headquarters and tell them hey we're going out to the pizza place and you can't go we can actually do that call emissions control uses the low bitrate codec it goes across the IP LAN but what if there's a failure what if there's a failure again you've got a client that can't reach it server the client will try three times to reach the server to go wham wham wham if it can't reach the server he's going to rehome back to a software application running in that router called srst and srst is going to have the local doll plan and the local facilities to know about the phones locally only for that site and it will be the call set up of control for that site so you can still call your friend here so it's eventually under than that he still knows those guys he still knows you can dial out to your PSTN and he still knows that if you do four digit dialing here's the way I dial it add the digits that send it to the PSTN Cisco had this in 2001 2001 this is this was the boy I'll tell you you think our competition hated this you ain't kidding this is brutal this was brutal for them that won that router makes a big difference their answer well a lot of time it took them several years to get an answer and then their answer ended up being a server out there a separate box that's not attractive this is what Cisco came up with so again srst it's built into all of our is ours you licensed it you licensed it in there you put the voice on it and does it well you know they'd probably pretty much given up on this by this point they price said you know what the cats out of the bag I can't do anything about this the good part about this is is now if I want to call four digit from here to here I don't even have a choice that I have to go through my PSTN so it actually means sometimes I leave a few more trunks to the PSTN then I would actually need just to the case this happens yeah that's what it does for me so it actually helped him a little bit does that make sense that makes it this is a differentiator folks still is today it still is today still is today because why you're gonna have people all over the place you're going to these sites and all this this is a something that we do very very very well well if that's fine that's fine but then again if you have a mobile phone what if somebody leaves you a voicemail message where do you want that message to be on the phone in your service provider if it's a business phone you want your messages maybe confidential information did you enforce mam yeah mmm I got a customers who don't like that they want all of their for business voicemail on their system they want to be able to forward it huh well in some of my customers again some customers don't want more stuff some people's voice minutes are critical for them they have distribution lists and they send out information as executives send out information to voicemail and then one that's how they use again different ages different uses think about it is is all customers are different well we can lean low jabber on your phone ya know jabber on your phone it's your business phone using communications manager and guess what we can do that when you walk out the door too if you'd like yeah again we're get it eventually getting there this is just building the story building the story so now that we've got the service up here called communications managers of this call set up and control right now just for phones we're gonna add to that it's going to be connected up on a network which is infrastructure the router is infrastructure the router is a voice gateway now inside of this voice gateway there's some unique hardware inside of that these DSP resources we have that's what makes that thing be able to convert traditional telephony PR i--'s into packetized voice it creates phone bridges for us so when we want to bridge in about your phones together and all that that's what that piece is a hardware and they're doing their interest at infrastructure as well the clients again could be the IP phone that we sell and we sell a plethora phones whether it be looking like that a little 9900 and all this that in the other we sell a software called jabber which is our client that could be on the PC could be on a Mac could be on an iPad could be on a iPhone could be on Android all of these are our jabber clients software clients those are their jabber clients communications manager does the setup and control again with licensing you buy a license for a phone the jabber clients what it the license for the Communications Manager you have the ability to download the Communications Manager software put it on the server of your choice we'll give you the specification for the server and again we'd love for that to be a Cisco server we also have another application that you can run there called our Cisco Unified presents server present server cups that's I am so with the license for the client after you get that you can download these two servers these two servers and this gives you the ability to do chat I am in chat and do voice yeah this is Cisco Unified present server Cisco's unified present server if you want voice messaging and again we've had that little discussion some people do some people don't cisco has another application another service out there cisco unity connection CUC is an application server that provides voice messaging so if somebody calls from the outside or somebody from the inside to my phone and i it ring no answer it rings for how many times communications manager can be configured to send that phone call to my voice mailbox it's just a bunch of hype it's a server with hard drives again can be virtualized can run in a UCS platform and everything Wow a bunch of servers in it just a bunch of servers is all we're selling here there are applications yeah well I well servers are I mean I guess that's a legacy so legacy yeah it's an application it's an application yeah I'm gonna start doing that it's an application huh yeah it's a virtualized application that can be virtualized it's an application that can be virtualized inside of there right so that gives us voice messaging I am in presence all of these across all of these port flow platforms across all of these now think about it if I have an iPhone and I load this on it then guess what I could take that iPhone not only inside of here but I could take it outside of here and actually connect back up that means my iPhone anywhere I want to use it it brings us back to security with once I walk outside of my building and I'm not using Wi-Fi and I'm using cell I'm going to get charged for that data service and one thing but I'm also connected to the inner I have to use the internet to get back through there so if I have the internet and I want to connect back up and I take my iPhone out there and I have jabber running on it this client has to log back into that server so we have to create a secure tunnel that secure tunnel is done by software called any connect any connect we have software that rides and was it's it's a always-on VPN client any connect is it runs on it can run on your clot all your clients it runs on your clients that can run on PC Mac whatever you want and it runs on their when you're inside of Cisco and you log into Cisco here it doesn't activate a VPN because you're in a secure environment you're using Wireless here you're using whatever you want as soon as you leave Cisco let's say you go to Starbucks or home or wherever you get an internet connection it realizes you're not on a Cisco network so it automatically activates and now your client has a secure tunnel back to its server behind the firewall it also will filter all of your webmail try web traffic back through there - let's filter your web traffic back there no no no with the licenses you get you can get presents the the basic license you get presencing this yeah the more advanced licenses we have you can have voice messaging and on you could you well you could get a universal license for that yeah you could get a higher-level license that gives you all this you can have actually have an IP phone and a mobile device we're the same user yes yes same same number mm-hmm 501 does it work does it work doesn't work all right so I'll say this it will work for 30 days and we'll have our reports come out and say you're over your license limit and on day 31 it won't work yeah well give you that period to be able to do that yeah I think Cisco's got that set up in Nano because they didn't like the fact that we were just cutting people off communications management that's where all your licensing goes so where our licensing goes communications Amanar is the centerpiece of everything we do everything we do
