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

[Ryan Huff]

Sort of sounds like you may have a Class of Service (CSS/Partition) issue with the SIP trunk between CUBE and CUCM, since that is most likely the most significant configuration change/add since moving to SIP, that could generate 404 responses.

Could also be an issue with the device pool on the SIP trunk, depending on how you have the dialplan structured.

CUCM Generally won’t issue a station not found (404) message, unless CUCM ingress element (the SIP trunk) doesn’t find the station; either because the station doesn’t truly exist, or doesn’t exist in the configuration context it has access to.

Regional problems would issue a 404 generally.

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.
