I am having an issue with one-way calling on a VOIP system. Basically I have three sites. All three sites can call out and can hear the remote person but no one can hear what they are saying. (We are using dynamic VPN)
I have a feeling it has something to do with inspecting H323 protocol but I am not sure.
I also should point out that all other traffic over VPN works just fine both ways

Hi Jacob,
When you call the other site they can hear the phone ringing I guess?
if so, then that means that SIP is going through, but what about skinny protocol. Also, can you try to run a Wireshark capture on both ends, for this I would suggest using SPAN.
here is the link to configure SPAN:
In that way we can tell if the traffic from 1 end is hetting COMPLETE to the other end.
Also, try to ping the other IP just to make sure that this traffic gets encrypted. If that happens then we can assure that the VPN is fine.
03-29-2013 02:52 PM
Basically on the remote-site they can hear the phone ring, they can see the extension lights and everything light up or go off whenever someone at the office picks up a line, but people at the office cannot hear when they talk.
So the person at the remote site can hear the office people, but the office people cannot hear people at remote sites.

Anyone have an idea? I still wasn't able to get any further on this :-(

I wiped out the config and started over. This is my current config with the exact same call problem (you cannot hear people from the remote offices):
