[cisco-voip] UCCX not working after change to SIP

[Dana Tong]

Hi all,

Customer recently changed from ISDN gateways (H323 registered) to centralised SIP and now the UCCX IVR isn't working.

The SIP trunk is set to use the 64K region and I did also try setting the CODEC to both G.711alaw and ulaw on the dial-peers on the SIP CUBE router.
It's weird.

The debug CCSIP messages are showing 404 not found, and the voip dialpeer inout were showing a match on the correct dial-peers.
But then the logs say no match as per below.

Anyone seen this kind of error after changing from ISDN to SIP?

Somewhat sanitised below. Trying to get RTMT access.
