Webclient no audio

[Ovidiu Pacuraru]

Hello,

we have a fresh install of 3CX version 16.0.0.1581 running on a Windows Server 2016.
The server is behind a firewall (Sophos UTM 9.6) with all required ports (https://www.3cx.de/docs/adminhandbuch/firewall-router-konfiguration/) forwarded to the server.

Communication with Android- / iPhone App and Windows Client is working perfect.

Our problem is the webclient. We can establish a connection, but no audio is transferred.
The selftest ( *777 ) is also not working on webclient.

My browser (chrome) shows the following error in console:


Thanks for your help!

Hi @Ovidiu Pacuraru

If this is a local server, can you try from inside you firewall using the internal IP?

https://internal_IP:SecurePort/webclient

Please provide some more info, like where is the PBX (local/cloud/remote) did you try to login from? (same office as server / other location outside the office) and if your pc hosts file has an entry for this FQDN or if you use a local DNS entry for your FQDN

lets see if I can provide more useful info after having tried a couple of more workarounds.

3CX Server is on a Server under our control and management in the cloud.
on this server we are running VMWare.
ALL external access goes through a VM which runs Sophos UTM 9.6 (latest update) which "used to" provide IPS, WAF and general firewalling.
We have turned all of those features off to solve this problem so the Sophos UTM only does the HTTPS termination providing a certificate from letsencrypt for users accessing the 3CX Server.
(There is a VPN tunnel between our offices and this server so as a workaround we have tunneled all internal traffic to the 3CX server and the webclient is working but we would like to get it working through the UTM without the VPN and ideally enable IPs and WAF functionality again)
