I have two cme's with unity expresses, when I make a call across the wan the call is fine however when the call goes to voice mail I see that it is forwarded but I can not hear the audio from unity.
Had a similar issue with the same setup. Ultimately fixed this by transfer-pattern commands. They were required for CME to hand off the call. 6100-6105 were various attendants and VM pilot numbers at the remote site. Remote extensions were in the 1400s with remote paging in the 400s.
Under telephony-service
transfer-pattern 1...
transfer-pattern 4..
transfer-pattern 61..
Your CME knows about it's own extensions but needs to be explicitly told which extensions it is allowed to transfer to. Until it's allowed to do the transfer, the remote CUE won't be contacted.
If the above doesn't fix your problem, try hard-coding G.711 as the codec under your dial-peer. By default they will use G.729 and I believe CUE can only do G.711.
The default-dial peer 0 will do any codec. Just make sure you have your remote dial-peer using G711. If you replaced your default-dial peer with a specific inbound dial-peer then the default is G729. Again make sure this is using g711.
I have tried the transfer-patterns although I did have a transfer-pattern .T already in the telephony-service. I am already forcing g711ulaw as the codec and have confirm this by way or call statistics. I can see that the call is transfered to the unity pilot number on the remote site but still no audio. If I call a number on the remote site that has no voicemail I am transfered to the operator, so I know unity express is pickup the call, but I still cannot get any audio out of the unity to a remote location.
I tried to do this but the problem continue, anyboby can help me? i am using an mgcp configuration on the gateways ... and from the PSTN the callers van not hear the autoattendant express.
