I have a CME and an AIM-CUE on the same router, which gets calls from a gatekeeper also, and MWI has stopped working from the CUE to phones on the CME and I am having trouble finding out why. I have been working with TAC on this for awhile also.
The CME receives and places calls from/to a gatekeeper upstream primarily and those ras (voip) dialpeers use g729r8 codec so that seems to be where the issue may be coming from, but this used to work and stopped. We have tried to delete the voip dialpeers, reboot the router, and add the CUE and MWI voip dial peers in first and no luck.
The IOS is 12.4(15)T and CUE is 2.1.x. The router is seeing the SIP messages per debugs but not setting the MWI.
I have also tried the sip-ua mwi-server global configuration in other forum posts with no luck. We can call the MWI on/off extensions from a IP Phone and it does set the light on and off fine.
