The calls get connected but no audio can be heard either end. This appears to only happen after our users have been using our 3CX system for around 4 hours. After the 4 hour mark we can't make any external calls without getting above issue. After this when we restart our 3CX server, it continues to work as normal.

In 3CX, go to the Activity Log from the dashboard and then look at the top line - Press the capture button and then press the doorbell.
