CUCM - Nortel CS1000 SIP GW Integration Modify INVITE header

2012-09-28T19:01:27Z

Hi Team, I'm working in a CUCM-Nortel Integration, incoming calls from Nortel to CUCM fails due the received INVITE from Nortel is in this format: =========== INVITE sip:333666;phone-context=udp@test.com;user=phone SIP/2.0 . To: ============ CUCM rejects the call and in the trace I see the reason: |Digit Analysis: Host Address=test.com DOES NOT MATCH any address for this cluster. |Digit Analysis: Host Address=test.com DOES NOT MATCH top level org domain. It makes sense since the CUCM is not named test.com nor the top level org domain. I can fixed using the test.com in the CUCM>Enterprise Parameters> but is not really the solution I would prefer to use. I’m wondering if I can use the Normalization Script to grab the phone-context= tag from the To: header and rename it from [url=mailto:phone-context=udp@test.com]phone-context=udp@test.com[/url]; to phone-context=udp@x.x.x.x; where x.x.x.x is the ip address of the CUCM. I read the doc and I think I can use the following function to grab the tag M = {} function M.inbound_INVITE(msg) local to = msg:getHeaderUriParameter("To", "phone-context") end return M But how can be modified? Any help on this is really appreciated. Regards Carlito
