One-Way Audio between two interconnected UCM's


Hello All,

Does anyone have any tips and/or tricks about how to fix one-way audio between two interconnected UCM’s. Location A can hear Location B but Location B cannot hear Location A.

Any ideas of what can be causing this issue?


How are they interconnected, VPN, open Internet?


VPN. I looked into the Peer Trunk and noticed that one side had NAT checked and the other side had NAT unchecked.


No NAT needed when using VPN.


Yes, thank you! I can officially hear from both sides.
