Here you can find a list of ports that need to be opened for the software-based TrueConf MCU server to work properly. To make the administration and integration of different solutions easier for you, the basic values are similar to the port ranges for TrueConf Server.
To find out how to open the ports, please refer to your OS or network equipment documentation, or contact your company’s system administrator.

Outgoing Network Ports Table
These ports affect only the outbound traffic from your corporate network, which means that your corporate communications will stay secure even if outbound ports are opened. Normally, the ports for outgoing connections are already open.
| Port | Transport | Protocol | What is it used for? | Is it possible to change? |
|---|---|---|---|---|
| 443 | TCP | HTTPS | To the registration server | No |
| 554 | TCP | RTSP | To capture a video stream from an RTSP camera | No |
| 1935 | TCP | RTMP | Required for the conference streaming | No |
| 5060 | UDP, TCP | SIP | For SIP call signaling | Yes |
| 5900-5910 | TCP | VNC | To capture a desktop using a VNC server | No |
| Unknown* | UDP, TCP | RTP | To send RTP traffic after the session is established | No |
| 20000-40000 |
UDP,TCP | RTP/RTCP | Required for WebRTC operation. Between server and the browser of user. | No |
* The port range is unknown and depends on the opposite side.
How to reassign ports
