Voice / Video Calls & Desktop Sharing not working

Troubleshoot : Voice / Video Calls & Desktop Sharing not working

1. Make sure VoIP Server is running

  • In Windows Services make sure “Output Messenger VOIP” service is running.
  • You can also verify it in Server Manager tool.
  • If Output Messenger VoIP Service is not running, Server Manager > General > Start “Output Messenger VoIP” service.

2. Check Firewall / Router

  • In Server, make sure tt4prosvc.exe is added in Firewall exception list.
  • Make sure to open port 14124 for both TCP & UDP. Also, do the needed port forwarding, if the Server running host is behind the router.

3. Enable Voice / Video Calls / Desktop Sharing

  • In Server Manager, Configuration > Client Settings, make sure Voice & Video Chat are enabled.

4. Check port access directly using telnet

You can make sure your Server IP Address & Port is accessible by using telnet application
For example:
if your Public IP Address is : 174.133.11.11
In command prompt, enter telnet [[ip address]] 14124

Note: If your system is not having telnet, enable telnet (Control Panel > Programs & Features > Turn Windows Features On or Off > Enable Telnet Client)
