[cisco-voip] Unity connection one-way audio

[AbdusSaboor Khan]

I have similar  issue in one of our branch, when outside caller want leave
message he can hear the greeting but unable to leave the message, Unity is
not getting voice and start telling the option press 1 to do this? although
we did not change on the gateway.
