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)
If telnet is able to connect with our server, we will have a blank window as below.
If not able to connect, we will have the connection failed message.
Only if telnet is able to connect, we can do Voice & Video calls.
If telnet is not able to connect, you have to check all above steps again.
