Hello
I managed to get the normal whatsapp working on my sophos utm home edition. But now the new whatsapp calls don't come through.
The signaling of the call works, the phone is ringing and I can pick up the phone, but I can't hear anything.
The caller on the internet even gets the normal beep sound, not busy.
Https scanning is enabled, setting it to URL only didn't help. Somewhere on the forum I read to open port 3478 UDP, did that, no difference. Application Control is also enabled.
Has somebody an idea what the problem could be?
Thanks
Roger
