[cisco-voip] One Way audio problem

Thu Dec 18 11:34:19 EST 2008

Try binding both your Media and Control onto an interface.. like your
Loopback Interface

Something like 

mgcp bind control loopback 0

mgcp bind media loopback 0

Hello folks,

I have incoming voice but no outgoing voice.

It's CUCM 6.1(2) to a 2811 MGCP FXO port.

There's no firewall or NAT for this application. 

Routing seems to be OK but I defer to you.

Let me know if there's anything else I can provide.

Any ideas would be appreciated

Thanks

Kevin
