I have an odd issue that started in the last couple weeks. Agents on IP Communicator, with built in bridge enabled for call recording, get one way audio for the first 15 seconds of the call when connected to VPN. After 15 seconds audio works. The remote agent cannot hear the other party. Does not matter which side originates the call. Call manage trace is showing media start event immediately upon connection. If I disable built in bridge audio works right away. Disabling recording on the line has no effect.
In my mind it has to be firewall/VPN related.
ughh... I think I saw something very similar a few years ago, but can't remember the details (and it was a different employer). Have you tried checking the box on the device level for "MTP Required"?
Hi @jason Bre,
Check this discussion of the community, maybe can help you:
I agree it has to be something on the firewall. The odd thing is that it starts working 15 seconds into the call. It also works immediately if I disable built in bridge.
