Class of Control: Partitions and Calling Search Spaces.

you the third thing we're going to talk about is class of control in class of control two of the most important things are controlling who can call where and controlling the geographic routing for who can call where we want all the phones in our company to be able to access the numbers they need to dial but we might want to restrict some phones too for example in the break room we may have a phone there and we don't want it to be able to dial to long distance numbers or international numbers geographic routing is also very important if you're in the Toronto office new dial nine-one-one you want that call to go out to the Toronto 911 call center or if you're in Peterborough and you dial nine-one-one from the Peterborough office you want that to go to Peterborough 9-1-1 and the fire department or the police department will end up at that office the first thing we're going to look at are the two basic concepts we use in class of control they are partitions and calling search spaces if there's a partition on the line it says who can call that line if this were my phone a partition says who can call me a calling search based on a line controls where can I call basically partitions are a name assigned to a set of numbers and patterns a calling search space is a list of partitions it's a list of the numbers that I can dial from my phone let's look at a simple example when you configure a line if you don't assign it a partition its callable from anywhere right now these lines don't have any partitions or any calling search spaces so everybody can call everywhere so let's assign these numbers some partitions I'm going to put these two numbers in the top partition and these two numbers in the bottom partition now remember that a partition is just a name assigned to a set of numbers so now that I have assigned partitions who can call whom nobody can call anybody because I have an assigned calling search space that brings us to rule number two you can only call a number if that numbers partition is in your calling search space what we had configured so far was a partition on each one of these lines and nobody could call anybody because we hadn't yet configured our calling search space so I went ahead and I gave these two lines the first calling search space and these two lines the second calling search space now the first calling search space has the bottom partition in it and the second calling search space has the top partition in it so who can call whom can I make a call from this line to this line intuitively people say yes you can they assume that if a number is in the same partition as yours you can call it the first number has the first calling search space this number is in the top partition so is the top partition in the first calling search space no it's not so you cannot make that call can I call from this line down to this line this line has the first calling search space this line is in the bottom partition since the bottom partition is in the first calling search space we can make that call if I wanted to call from here to here then the top partition would also have to be in the first calling search space let's just look at one more example let's say I add extension to 666 I haven't configured any partitions I haven't configured any calling search spaces on this line so who can call it anybody here can call this line because it's not in a partition this line can't call anywhere because it doesn't have a calling search space unless there's another extension that's not in a partition then this number can call here because it's not in a partition remember our first rule you can always call a number not in a partition and our second rule you can only call a number if that numbers partition is in you're calling sir face on the whiteboard I have a list of the rope patterns that we configured in another lesson we learned that a rope pattern points to a wrote list so I can figure it a route list for headquarters PSTN now we want to use partitions in calling search spaces to control who can call where four partitions this is a traditional way of doing things the first partition I have is headquarters internal partition which actually doesn't contain a wrote pattern it actually contains a list of all of the directory numbers in the headquarters building so the headquarters internal partition will include a list of those directory numbers we have our emergency partition which includes both our emergency numbers 911 9.9 1:1 we have a service partition that contains all of our service numbers we have a local partition which contains our two seven digit patterns as well as our ten digit pattern we have our long-distance partition for long-distance numbers in North America and an international partition for our international dialing now remember this partition has to be in your calling search space in order for you to access those numbers so you have to have the headquarters long-distance partition in your calling search space in order to call a long-distance number so let's have a look at some calling search spaces so now I've built my calling search spaces I have headquarters internals no 911 service now you want to make sure that if you have a calling search space with no 911 that you put that in the name now you're thinking to yourself well what would I want to have a line that has no 911 access but this is a calling search space for incoming calls on a gateway or a trunk so that would just include the internal partition I have headquarters internal calling search space which includes internal and emergency partition that might be for a lobby phone or a phone that you have in an elevator we have the headquarters local calling search space which includes the local numbers service emergency and your internal numbers that might be a student phone or you have that one in the kitchen our headquarters long-distance calling search space includes long-distance our local partition our service partition the emergency partition and all of our internal numbers and finally we have our headquarters international calling search space and that would include our international partition as well as all of these ones listed finally I'm going to add the pattern nine one nine hundred ex ex ex ex ex ex ex as we all know a 900 number is a toll number and if I allow anyone to access that number we're going to cost the company money so what I have to do is block that one the way I'm going to block that number is to add a restricted partition and that number will be in a restricted partition I'm going to make sure that international and long-distance have the restricted partition in they're calling search spaces because if I don't do that they can match the pattern 1 900 right there so that way when they dial 1 900 it matches this pattern here and it's blocked however some people are allowed to dial anywhere to any number so we're going to add a calling search space we're going to add the headquarters unrestricted calling search space and by leaving this partition out and all of these partitions in its unrestricted in they can call anywhere so now I control who can call where we have the control to say where you can call who has restricted access to where they can call and who has unrestricted access [Music]
