VoIP Basics | Real world implementation | Voice VLAN configuration(Packet Tracer)

hello guys welcome back to the channel and today's video is about voice over IP and voice VLAN so this video was requested in the comment section and I think this is a really good topic for networking as well so in this video we will talk about what voice over IP is and its advantages how we use voice over IP at work implementing voice over IP and we will do a voice vand in Packet Tracer okay so if you are interested in knowing more about voice over IP at work and also configuring Voice v in a lab please keep on watching and without further Ado let's get started with today's video okay so to simplify voice over IP it's a technology that allows you to make phone calls using broadband internet connection instead of the regular phone lines which are analog so if you're familiar with landline phones they are using a different technology called pots or pstn and it's using basically copper wire to connect to phone lines so in voice over IP you can use a phone just like what a landline kind of looks like and it instead of using a phone line it uses ethernet just like how we connect our computer to the internet okay so most businesses nowadays in this time where internet is mostly used Voiceover IP is commonly used in the business sector because of the cost savings that you can have when using this instead of the regular phone lines it's scalability flexibility and also its integration to different technology as well so Voiceover IP comes with a lot of different features just like call forwarding voicemail conferencing call with no extra cost that's why it's also cost saving for businesses to use it also another great thing about Voiceover IP is the scalability it's so much easier to add and remove phone lines using Voiceover IP because it's not costly it's way cheaper than having a new infrastructure or a new phone line just for or adding a new phone so if you already have a switch at work you can use IP phones that have power over ethernet capabilities also one of the advantages of having voice over IP is the integration with different apps just like messaging apps and other collaboration tools and this comes at no extra cost also so it's very cost effective solution for a business so the phone that we use for voice over IP is called the IP phone and this allows users to take calls using an internet connection so there are also different types and makeing models of IP phones there's the polycom phone the grand stream phone Cisco phone and more and I'm going to show you what we use at work we use a Cisco IP phone 8851 okay so let's look at it at the back so here's the different ports in the back of the phone okay so there are three ports in here on this side so one is for the ethernet this is Poe and this is what we use to connect to the network so it will turn on the phone and on here in the middle is the access port so this is an extra Port where we can connect the computer so this is our IPO Network and there's two cables connected to it one for the network switch and one for the computer so this ethernet cable that is plugged into the poe Port is connected to this wall jack that's patched in to our network switch the ethernet cable that is plugged into the access port is connected to my computer that gives it network access so I think that this is also a good solution to minimize the switch Port that you are using so instead of using one port for the phone and one port for the computer you will just use one port for both the phone and the computer thus minimizing the amount of switch that you will use which is also cost effective and can save you money on devices okay so now that we have talked about voice voice over IP now let's move on to voice VLAN and these two are related because we use voice landan to implement and deploy voice over IP technology so voice VLAN is a feature and network switch that segregates data traffic from voice traffic within a land so going back to our example earlier because most Cisco phones have an access port you can use it to connect the computer to the phone and then to the switch so you will only use one switch port instead of two and for us to be able to do this we can use the voice Vin the advantage of this setup is that you will only use one switch port for the computer and the IP phone there is an issue with this setup though because we have two devices here the phone and the computer their data will travel and just one Link in here going to the switch best practice in networking is to prioritize and manage voice traffic separately to ensure high quality voice communication for voice over IP systems voice traffic requires realtime transmission to ensure that our phone conversations remain clear and uninterrupted so for us to prioritize voice traffic we can use voice VLAN to separate voice traffic from data traffic all right so now we can get started practicing our voice VLAN configuration in Packet Tracer and if you have Packet Tracer you can just follow along so what you need are the devices first of course all right so we are just going to put a switch in here an IP phone and a computer and you can all see that from down here so under the end devices is the IP phone and the computer and now we just have to Cable it okay so now we will cable it so let's start with the computer in here just click on the cable click on the computer and select fast ethernet then click on the phone and select the PC because we are connecting the PC to the phone now grab another cable and then click on the phone click on switch and go to fast ethernet one or any ports and then of course as you can see the light is red which means that it's not going through traffic it's not going through yet that is because we have to turn on our IP phone so in Packet Tracer it is off by default so what we're going to do is to click on the IP phone and go to the physical and click on IP phone power adapter in here and you can see the power adapter at the bottom and just drag it and just plug it into the port I'm going to zoom in so you can see so I've shown you earlier where the power port is so it's this round port in here just connect it to that and as you can see the light starts to turn green in here and it means that it is now powered on okay since we are going to have two vlans in here the data VLAN and the fan this link that goes from the switch to the phone is going to be a trunk that has 81. Q which is a VLAN tagging protocol that identifies what kind of VLAN goes into the switch so we have 801 at Q and here so that the switch would know which VLAN is the voice VLAN and which one is for the access VLAN so the concept for this is that it's going to act like a trunk but in the configuration later on it's not going to be conf configured as a trun Port but you will see how it will be configured as voice VM okay so let's get started configuring this now so let's go to the switch and CLI first thing that we have to do is to create the two vlans the data VLAN or the access VLAN and the voice VLAN so's type enable configure terminal VLAN 100 and then let's name it like the data or let's name it computer for this example and then let's create another VLAN VLAN 200 this is for the phone okay next is that we have to configure the port in here which is fa01 as an access port okay so let's go to that interface and oops f01 and then and just do switch Port mode access and now let's configure it as an access VLAN first so let's type in switch Port access VLAN and the VLAN number for the access VLAN which is 100 and then switch Port because this is a voice VLAN we are going to use the command voice because we are configuring it as a voice VLAN to and and VLAN then number 200 because that's our voice VLAN number and if you don't see any errors in here it means that your configuration is correct okay so if you wanted to verify now that you have configured it correctly just do just do this command show interfaces and then the interface number fa01 for me and type in switch port and if we look in here closely you would see that access mode VLAN is set to 100 that's our access vland and voice vant is set to 200 which is our voice VLAN so it should work now and as you can see it is lighting green now which means that the interface is up okay so that's how you configure Voice vant and that's the background on what a voice vant is and how it works okay so that would be it for today's video I hope you learned something about voice over IP and voice fan if you have any questions please feel free to leave it in the comment section down below and hope to see you guys in the next videos thank you so much for watching
