Any logs?

sip integration between cucm 6.1.2 and nortel system problem

Hello

I've given up installation of SIP trunk between CUCM and Nortel CS1000 rls 4.5

Nortel rls 4.5 is very old.

As far as your problem is concerned, Nortel uses a proprietary SIP message that includes a "phone-context" information behind the standard SIP syntax. Many endpoints do not understand these messages.

And also I've discovered that with rls 4.5 the Session Description Protocol is encapsulated into MIME. Message body -> MIME -> SDP  => this is not standard.

Could be the cause of your problem.

Also try using IP instead of FQDN names when talking to Nortel, otherwise it does not work. Your error message indicated an invalid uri value. Sniff what CUCM sends to Nortel.

Consider using QSIG for interconnection. It works and allows basic features.

Hi,

The nearest compatability config doc I can see is

CUCM 6.0 to Nortel CS1000 Rel 4.0 via SIP

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/pbx/interop/notes/616799nt.pdf

May be some pointers here especially with the Nortel side of the set up.

Hi Ayoussef,

I only need ccm log on all servers conver non-working calls so I don't believe it will be large.

Cheers
