Cisco Router as SIP Server

[Scott Hanson]

                   Hello,

I am working on a  solution to allow 4 digit dialing between Call Manager and an Altigen phone system.  The Altigen needs to register to a SIP Server.  Can a Cisco router be configured to be a SIP server?  Desired end result is to have calls come out the SIP trunk on the Altigen and get over to Call Manager.  I was thinking if both systems had SIP trunks up to the same router I could route the calls that way.  Anyone care to confirm or correct?

Thanks in advance.  All replies rated.

Hi,

certainly, a router may function as a SIP proxy, but is there any reason you cannot use CUCM as the SIP registrar for that Altigen system?

I knew I could to CUCM to CUCM over SIP but was not sure about CUCM to Altigen.   Thanks Gergely!
