Chrome Webclient - no sound when making calls

[r19h72]

After a recent update of chrome or the web extension I'm facing a strange problem. Before it worked. Now I've got the problem, no matter which computer I use (office, laptop, home) and where I use it.
When I receive calls, everything is fine.
When I make calls, I hear the ringing but when the connection is established (the connection time starts to run) there is only silence (on both sides). There is no difference if I call a 3CX extension or a external number. My current workaround is making calls with the Android App. So there is nothing wrong with my extension on the PBX side.
Could it be that the PBX is confused if there are several instances of the extension active?

Have you updated the PBX to the latest version, if you are not running SP6 there is a compatiability issue with Chrome?

Hi,

Since you face the issue on multiple locations, you should look at your PBX. The entire RTP range must be open so check it again - even if it worked before https://www.3cx.com/docs/ports/

The firewall checker is a good starting point, but note that it does not check the entire range, only the first few and last few ports so you can still have an issue even if it passes for this specific scenario.

Thanks for the answer.
We are using 16.0.5.611.
619 is available for installation.
What is SP6?

You will need to update 3 versions but keep upgrading until you reach 16.0.6.641, I am certain this will fic your problem.
