CUCM - CUBE - ITSP 302 move temp

Gert Plessers

I need to connect a CUCM (10.5) via CUBE to a SIP Trunk. All seems to be well, but when forwarding an internal-number to a cellphone eg the carrier is expecting to see a 302 move temporarily message (when called from outside - on a trunk/trunk call) and not an invite with a diversion header. Is there a way to have CUCM use this 302 instead ? I guess it can be done by creating a SIP normalization script but just wondering if there is not an easier way.

I believe CUCM does not support 302. CUBE won't do a 302 in this scenario as well. This is one of the stranger requirements from an ITSP to support 302 from a CE.
Post in the devnet community and see if the complete message can be changed to a 302.

Thanks Nipun (+5). It seems CME supports this but that doesn't help in this case.

Thats right. CME does this when acting as a redirection server.
CUBE is a B2BUA here. CUCM does not support 302 either.
Also changing the complete message would fail the calls since the 302 needs to be generated on the same leg you received an invite on. You are trying to send a 302 on the forwarded leg instead. This would mess up the SIP state machine and obviosly result in call failure.
