RE: sip trunk

Asim,

I would read through this document which outlines a majority of the concerns.

With 5.1 I would recommend connecting your CM to CUBE and having it deal with the SIP trunk.

Dear experts,

I need to connect my CUCM 5.1 with sip proxy on telco side.IP phones will connect to CUCM.
The SIP server provide 90 lines with real numbers

Following is the scenario.

Cisco IP phones----------CUCM-------WAN connection to telco---------SIP proxy server.

Can anybody explain me how this will work, what will be the configurations and if CUCM has the capability to control the calls between IP phones and SIP server.
