I have a problem that I can't get solved. I have tried Elastix/Freepbx as well as Asterisk version 1.6/1.8/10
The problem is as follows:
When I use a ECN trunk and I do any recording/monitoring of phone calls one side of the conversation is garbled - it sounds like the person is underwater. This hold true for all our installations regardless of what endpoint devices, routers and PBX used.
Both of the people involved in the phone call can hear each other fine. When I do an internal call I can record both parties or monitor the call without a problem.
I tested with a Telfree trunk and I don't have this problem. Calls record fine. I then told ECN this and they say they can't reproduce the problem on their side when recording any of our calls and basically can't help me/
I'm using G729.
