[cisco-voip] 1760 V Gateway and VPN connection

[Travis Llewellyn]

I have a strange problem that I am perplexed on.
We have 2 locations that have 1760v's with FXO cards and are connected
to our main site via a LAN-to-LAN VPN Connection.
Calls coming into the 1760 and going to the local phone work great.
Calls coming from the 1760 to VM at our main site just go dead. The
connection happens but you can not hear anything on the line.
Calls coming from the 1760 to a phone at the main site have the same
problem.  The connection happens and it shows a connection but audio
both ways are silent.

I think it is a routing issue from the gateway but I am not sure how to
prove it.
I can ping out CM server and Unity server from the gateway if I use the
inside interface. But I can not if I use the outside (to be expected).
But I am wondering if by chance the connections coming into the 1760
somehow have a source address of the outside interface of the router.

Any help would be appreciated.
