I seem to have a poblem across my wan. I have CME on 2851 with unity express 2.3 on both sides. When I place call across the wan the call is fine, however when the call should transfer to voicemail I get a fast busy. I should also mention that I can only seem to use g729 across the wan, when I try g711ulaw the call fails instantly. Any help you be great.
Maybe I have another problem, when I call the second location and the call is not answered the call should be forwarded to the voice mail pilot number, that is when I get a fast busy. It seems that the originating CME is trying to transfer the call rather than the CME that was called. It would seem that the CME on the far end would transfer the call itself? help
By default G729 is the codec on dial-peers. Make sure that your dial-peers have a voice-class with a g711 codec at the top or specify G711 on your dial-peer. If you are matching your inbound calls on the default dial-peer then you don't need to worry about the codec configuration on that end. The default dial-peer supports all codecs so it should negotiate g711 as long as your sending router is doing g711.
Here is a doc on the default settings for dial-peer.
