[cisco-voip] Unity Connections (Native Transcoding)

[Pat Hayes]

You are saying that when you have UC setup to advertise G711 and G729,
your G729 calls to it work, but when it is setup to only advertise
G711, G729 calls fail? That sounds like UC is transcoding just fine
and the problem is with your hardware transcoders. Have you verified
that the transcoders are listed in the device pool/MRGL associated
with the voicemail ports and that other devices with that same device
pool are able to complete similar call flows?
