No Audio one way, X-Lite

[dcarrion]

Hello

Yesterday the 3CX with X-Lite clients was working fine tunelling across a private WAN with a couple of extensions. We had conferencing going, multiple calls, external voip providers etc...

This morning when we try to use it, there is no audio on one end of the phone. We call an internal extension and the person at the other end hears nothing. We have tried this on multiple computers calling different extensions but same thing. I have also tried reinstalling the server.

Why would it drop out like that?

Here is a snipet of some curious logs:

And then there's logs like this which shows nothing wrong however still no audio at one end.
