Welcome back everybody, it’s now time for another networking, how-to video, this time. What we’re going to do is build a voice-over-ip topology with a couple of working phones by way of preparation, I’m going to use the previously configured DHCP and TFTP routed. So we do a show run here. We can see that these are the two parts of my configuration that I put up in the other video, so there’s the DHCP pools and I’ve got the cheap cheapy stuff, and I have my interfaces up and running here. That’S about it, the topology instead of having pcs in it, is going to look like this. You can see now that my router is going to be serving up DHCP and TFTP, but it’s also going to be the call server. My switch the important detail there is that it is going to be p OE now with the VoIP deployment. Normally, you would have lots and lots of VLANs separating your your Wireless and your voice and your pcs, I’m not going to worry about that for right now, because what we’re concerned about is actually getting the phones to call each other now, when you’re building a voice Over IP configuration, at least on a Cisco, there are primarily two parts that we’re actually worried about. One is what the phones are doing, so you got to do a little configuration specific to the phones and then what we’re going to do is some configuration. That’S specific to the call server itself so first up we’ll take care of the call server and they do telephony service. Note that my prompt has changed and they will do key phones here and we’ll just say five right now, and it will also do max down them. Number five will keep that the same loops spelling counts everybody. Now we have to tell the phones and the call server which interface to use, and so what we also need is an IP source address here and we’ll use one a to 168, 1.2 54 Cisco skinny sccp answer’s up on port 2000. So, really that ok, we’re good there, I’m going to add a system message to to create okay, I didn’t do any reason. We’Re getting some error messages here is: I haven’t, set the clock up and things like that, it’s nice to have that you should, on a regular deployment, make sure you’ve got NTP running, but I’m not going to worry about it right now. We’Re just trying to get some phones to talk to each other. That ought to pretty much do it for the call server side. Basic configuration note that this is a single call server and it’s not talking to anybody else, and if I forget anything, we can always just come back. So I’m going to do a phone in Cisco land, at least in the call manager Express the phones are actually going to be called key phones. And so our first dial number will do something like this and we’ll do the same thing. But with another yvonne and we’ll make this one alright, so that gives me 2 e phones, but it doesn’t really help me too much. I haven’t tied these phone numbers to a particular phone, so the next thing that I need to do is actually say: look keep on. One can be found at this particular MAC address. Now, there’s a delimiter here but period, it’s a little weird way to break up break up MAC addresses, but that is Cisco. So do that and I’m also going to tell it that I’m button one. We want you to use number one this guy and that will do a phone and I’m going to go through the same process. We need a MAC address for this guy. These guys share some commonality here. Oops now, if I screw up the MAC addresses Cisco, is not very forgiving on this, but number one is going to be number two okay and if I haven’t forgotten anything theoretically that should get us taken care. Nobody at this point. By doing he phones, I can see that I’ve got them configured here, but obviously nobody’s up and running. So now what I’m going to do is plug in my Yvonne’s there’s one there’s two so now my phones are actually they’re powered up and they’re coming up via Power over Ethernet on the switch. So all I did at this point was plug these two guys in you can’t see it, but the phones are coming up and whether they’re just going through there they’re booting process. Now this video is not about how this whole thing works, but I will tell you that right now the phones are getting IP addresses from the DHCP server and then, if they need to they’ll, hit the TFTP server and pull configuration items down so we’re waiting for Them to register a little bit still booting just saw the registration messages there we go so now we see that the MAC addresses have the map. The phones with these MAC addresses have now pulled IP addresses from the scopes that I created earlier now for the magic. I’M going to try and call one phone from another, so I just picked up, and hopefully you found that you heard that hello, ello ello and we are operational and that is about it for a Cisco basic call manager Express configuration setup. The e phones set up the telephony service and you are ready to go as long as you’ve got that DHCP and TFTP also pre-built. Well, that’s about it for this particular video thanks very much for watching. Thanks for listening and remember, it’s networking you can do this.
