[cisco-voip] ccm7/unity7 one way audio

[Ted Nugent]

What interface have you bound your MGCP to on the gateway? "mgcp bind" bind.
Its sounds as though the Unity server can not reach that IP address. Log
into the Unity server CLI and try to ping the remote gateway. My guess is
its bound to an interface not reachable by the unity server, and/or the
subnet mask or default gateway on the Unity server are wrong. Those are the
most common issues for 1 way audio in that direction. HTHs
