CIPC2.1.3.0 over VPN to CIPC2.1.3.0 over VPN -no audio

Using

CIPC 2.1.3.0

VPN 5.0.02.0090

2821 Router

CIPC is working fine in all scenarios (e.g. CIPC over VPN to 7941) except:

CIPC over VPN to another CIPC over VPN call is connected but there is no audio in either direction.

Anybody have any ideas?

Thanks

Hi Sean.

This is probably not a Telephony issue at all, this is most likely a VPN problem. Your VPN device may not currently be allowing ip packets to flow between the two remote endpoints. I use a VPN 3005 concentrator and I had to explicitly allow this ability in my VPN configuration before any of my VPN endpoints could make any sort of direct connection between each other.

Hi Adam,

Ok, thanks, I'll take a look at that angle.

Where, specifically, did you configure this on the concentrator?
