I have setup Zulu on other appliances that are working just fine, so this is quite confusing. This appliance is PBXAct 15 with Asterisk 16. Here is the situation:
- User is on home Internet --> Zulu app logs in and connects just fine --> WebRTC won’t connect
- User is on mobile data --> Zulu app logs in, connects, and WebRTC works perfectly
This has to be a NAT issue, but I have replicated my settings from my other working appliance. I am using the ICE option to map the local IP of the appliance to the public IP, which has proved to be more reliable than setting a STUN URL.
Anyone have any ideas? I REALLY do NOT want to switch to Sangoma connect right now if I don’t have to. It is still too new, plus I am very uncomfortable with opening the SIP ports publicly. That was the advantage of Zulu.
