SIP-to-SIP fails to handle 302 Moved temporarily message

Scenario:

AS5350XM running 12.4.15(T)7 with UBE (ip-ip gateway) code.

This box is acting as a gateway supporting PRI trunks, a hosted VOIP provider, and some users with SIP IADs.

The hosted VoIP provider uses a hostname as the SIP peer for load-balancing and redundancy. When it receives an INVITE, it returns a 302 redirecting the call to a contact of the IP address of the actual gateway for that call.

Calls from the PRI trunks to the 5350 properly handle the 302 and send a second INVITE to the IP, the call completes normally.

Calls originating from a SIP IAD (sip-to-sip) go through the same initial scenario, but the 5350 fails to honor the 302 and sends another INVITE to the hostname, resulting in another 302, looping and not completing.

I can't find anything in bug tool, have tried several options under the voice service voip config section with no luck.

Re: SIP-to-SIP fails to handle 302 Moved temporarily message

To configure SIP-to-SIP connection types, perform the steps given below:

Router> enable

Router# configure terminal

Router(config)# voice service voip

Router(config-voi-serv)# allow-connections sip to sip

Router(config-voi-serv)# exit

Indeed that works and is the first step. The missing command to have the system honor the 302 moved message was:

voice service voip

no notify redirect ip2ip
