I'm just thinking more about what you said.

If it's just a matter of using the external ports, then wouldn't a workaround be to also port-forward the port range normally only used for internal calls? I know I tried that when I was testing and it still didn't allow audio on calls. But maybe your fix does more than just use different ports, in which case it would be fine.

Please we need information is this bug fixed in 3CX v10 service pack 5:

"The bug is fixed and the fix is being tested in our test lab. Should be available with next update.

One comment about the fix, though.
The fix doesn't change IP in PBX's Contact (it is still local IP, but who cares since TCP or TLS connection is already established). The fix just makes PBX to use external range of media ports in SDP."


We have the same issue, please help.
