WebRTC problem.

[BesOn]

Dear, community members and 3CX staff.

I have configured 3CX WebRTC on our company, but problem is - no sound (caller, destination)

Version of 3CX is 14 SP3
STUN server is disabled.
Firewall rule on 3CX server created (ports 9000 - 9500 UDP allowed)
Tried both browsers Chrome and Firefox.

I am trying to call also from internal network, without proxy and firewalls. Call establish but no sound again.

Here some logs from Activity Log

How many devices (different computers) have you tried this between? Could it be a PC sound card/device issue? Did you run the 3CX Firewall test with all tests passing?

Problem is not in devices, because we have IP phones too. Tried on 3 computers and 2 IP phones. Mics and headphones also working properly

We can not run firewall checker, because people is working with 3CX. UDP ports 9000 - 9500 opened.
