Re: I just gave that a shot on

lkoutsavlis · ‎12-09-2016

I'm running a Cisco CUCM with multiple partitions along with a SIP trunk connected to another SIP based PBX used as an IVR. I'm able to place calls from any registered softphone or IP Communicator phone through the SIP Trunk and have IVR answer the call. IVR is also able to originate it's own call to one of the Softphones or IP Communicator phones without a problem.

When IVR attempts to perform a transfer via (REFER) from a softphone to another IP Communicator phone or vice versa we are getting a 404 User Not Found response. Any direction\help would be appreciated. I have this working on CUCM 8.6 but without TLS if that matters at all

I'd treat the SIP trunk like an Cisco Unity Connection SIP Trunk integration. I haven't found Cisco documentation on the actual definition but this has solved a couple of issues for me in the past when integrating with Unity Connection. When a call reaches Cisco Unity Connection from an inbound call it is then transferred to the opening greeting. Your IVR is trying to do a transfer so this sounds similar. I'd recommend on your SIP Trunk Configuration page to check the "Redirecting Diversion Header Delivery - Outbond" on the Outbound calls section. And for safe measure check the option on the Inbound Calls also. "Redirecting Diversion Header Delivery - Inbound". Let me know if this works for you. DASH

I gave that a shot setting both Inbound and Outbound Redirecting Diversion but not luck. I thought that was going to be it. Thanks for the recommendation.

dashoward · ‎12-12-2016

Do you also have Run on all nodes checked on the trunk configuration page?

lkoutsavlis · ‎12-12-2016

I just gave that a shot on both of my SIP Trunks along with the Diversion settings for inbound\outbound. Same results.

I too am having this issue. I was wondering if you ever resolved it?
