I have installed Zulu and set it up and it can connect to the PBX fine.
If I make a call from or two the zulu soft phone on I can not hear any audio at either end.
I have tested with all firewalls turned off but still no joy.
Anyone got any ideas?
(My normal desk phones work fine on the same network)
I have fixed zero way audio on Zulu calls by setting a STUN server in Settings, Asterisk SIP Settings.
Thanks for the tip I will try this tomorrow.
I’ve not come across STUN before, does it have any downsides?
If the STUN server stops responding, sip can stop working.
