Trying to setup SIP Phones

Hello, I'm new to trying to setup SIP Phones on a cisco 2921 router that has CME 12.0 I am using Cisco CCP and get the following error messages:

 

SIP related configuration is missing that will enable the VoIP network to support SIP endpoints.

 

Configure SIP to SIP Connection and Local SIP Registrar from VOIP Settings.

 

Also, I will be using a SIP connection from my ITSP vendow

Hi!

This error indicates that you have to enable sip registar and allow sip to sip connections first.

 

Connect to your router via CLI (console, telnet, ssh).

And enter commands:

 

conf t

Voice service voip

           allow-connections sip to sip

 

 

Sip

registrar server expires max 3600 min 3600

Bind control source-interface loopback 0         --->here you should specify your interface for media and control messages.

Bing media source-interface loopback 0

I will be using my voip phones without connecting to pc's! can I setup a voice vlan only and include the ports that I will be using? or do I need a data vlan as well?

You can just use the voice Vlan, without the need of the Data Vlan if the ports on your switch for phone only use.

Data Vlan will not be required in this case

when I setup the vlan does it have to stipulate voice vlan?

 

EX:

vlan 66

name Vlan66

ip address 200.200.200.10 x.x.x0

 

or:

vlan 66

name Vlan66

voice vlan?

 

you just need to create the vlan then assign it to the interfaces and a dhcp pool in the router
Switch (config)#int range g0/1-24
Switch (config-if)#switchport voice vlan 66

Hello,

I believe that the following link provides you the full idea of how you need to configure your CME

 

https://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-express/99946-cme-sip-guide.html

 

Make sure that the "Voice Register Global Parameters Configuration" Section is clear to you.
