I've not seen this failure before today.
I saw your ticket and replied to it with info just now. Since your calls connect, but the audio isn't getting through, that means the call connects but something is blocking the audio stream. Per the ticket, please setup port forwarding and no SPI firewall is blocking the connections.

That should resolve your issue.

As for why it would happen sometimes and not others...every call uses a random port between 35000 and 65000 so depending on the port used your router may let some through. That is pretty common especially with newer routers that want to "manage" all your traffic for you. In that case port forwarding almost always resolves it.
