webrtc no audio, no RTP packets

[opalbiz]

I've setup 12.5 with Webrtc but I cannot get it working at all. No audio between the callers. Webmeeting is working fine, so I know the firewall is setup properly for the RTP port range. Anyone else having this problem?

We are experiencing the exact issue click to call calls setup works correctly and you can use the chat feature on the call but no audio or video packets. Our web meeting works correctly.

We faced the same issue in case when IP address of 3CX machine was changed after the installation of the 3CX software.

The solution, that worked in our case was:
1. Create 3CX system configuration backup
2. Find *.xml file in the root folder of backup archive
3. Locate the followind tag in this XML:

<DNProperty>
   <Type>String</Type>
      <Description>local address of NIC which will be used for WebRTC media connections.</Description>
            <Value>xxx.xxx.xxx.xxx</Value>
      <Name>WRTC_INTERFACE</Name>
</DNProperty>

if the value is your old IP address change it to the current one.


4. Place all files back to zip archive
5. Restore configuration from this archive

I didn't fount any item in GUI to change this parameter, seems to be a bug in UI.

for audio to work you must disable STUN in settings, network.
