When I call an external number or even the *60 talking clock, the zulu client will call, the destination will receive the call, but no sound from either side can be heard. The only thing I can see in Zulu is this windows. Notice the “connecting…” message at the top.
I use the same pbx with 3CX and it works fine. I opened all the required ports (8002, 8089, RTP ports, Stunt server port, 5060-5061), still no audio from Zulu.
