1719
1720 TCP
3000-4000 Via Technical Support
5060 UDP, TCP SIP Between the server and SIP device yes

554 TCP RTSP Between the server and CDN or RTSP client. no
443 TCP HTTPS Required for WebRTC. Between the server and user’s web browser. yes
1024-65535 UDP SRTP Required for WebRTC. Between the server and user’s web browser. Via Technical Support

TrueConf Server Control Panel

TrueConf Server Control Panel enables administrators to manage the server from any device on the corporate network.

Please make sure that the firewall of the server allows connection through the port used by TrueConf Server сontrol panel .

Web TCP Port (control panel port) and Database TCP Port (database port) are specified during TrueConf Server installaton. By default the ports are 80 and 5432 respectively, however other available ports may also be selected.

You can change Web TCP Port without reinstalling the server. To do it, please open your server working directory (C:\Program Files (x86)\TrueConf Server\httpconf\conf). Open listen.conf file using text editor. Please make sure to do it with administrator rights. Change port number in the parameter name Listen (e.g. Listen 8888 ). After that, save the file and restart TrueConf Web Manager service.

After that make sure to restart TrueConf Web Manager and TrueConf Server (it is important to restart TrueConf Server using Windows system and not TrueConf Server control panel). To do it, open Run command (press Win+R), type services.msc and click OK. Right click on TrueConf Server in the list of the services and select Restart. To restart TrueConf Server Web Manager, click Restart as well.

When you are using non standard port (other than 80) to access TrueConf Server control panel, don’t forget to specify it in URL. For example for port 8080, control panel address will look like

localhost:8080

 In this case guest page address will look like:

192.168.0.1:8080/guest

192.168.0.1 is TrueConf Server IP-address.

Media data exchange with client applications

By default, the exchange of media (audio and video) between the server and client application is delivered through the TCP port 4307. But you can change it in the settings of TrueConf Server сontrol panel (tab Network >Network Settings) to another TCP port of your choice:

Add address

To allow users to connect to the server from an external network, add a Public IP (external IP) in the Network >Network Settings tab (in the field External addresses). After changing the port to an external, go to the Web > Settings tab of the web configurator and change the External Web URL to Public IP (that you indicated in the External addresses tab). Then restart the server so that external users can connect to the server:
External Web URL

Please note that client applications should be downloaded from the guest page of your server. If you have changed the port value on the server after the installation of client applications, all client applications need to be reconfigured manually to use new server address and port.

Connection between TrueConf Server and a registration server

A connection of your TrueConf Server machine to our registration server is established through the TCP port 4310 after entering a registration key on the registration page of TrueConf Server.

If the server is behind a firewall, you need to grant access to the Internet through the port 4310 (proxy is not supported).

TrueConf Server Free requires a persistent connection to the registration server through the port 4310.

This port cannot be reassigned.

Interoperability with devices over SIP

TrueConf Server users can make calls to PSTN, PBX users or other endpoints that support SIP. SIP does not transmit any data, this protocol serves as a gatekeeper to establish connection between two devices. This protocol provides signaling, registration and session initiation. These actions are carried out through the port 5060 (TCP, UDP). If the port is closed, the devices cannot establish a connection. If required, you can change it manually in TrueConf Server control panel settings (Network >Gateway):
Default SIP Proxy
You must allow a port value to range from 6001 to 8001 (UDP) between a server and endpoints (also relevant for H.323) to enable TrueConf users to exchange media data with SIP subscribers.

Interoperability with devices over H.323

H.323 endpoints are registered on TrueConf Server through the port 1720 (TCP), and the ports 1718 (UDP) and 1719 (UDP) are used for signaling and session initiation.

H.323 standard is used by H.323 endpoints and consists of at least two standards – H.225 and H.245. Port 1720 is used by H.225 and port multicast 1718 is used by a broadcast quetry when searching for a gatekeeper within the local network. H.245 uses the range of TCP ports 3000-4000.

Before opening these ports, make sure that the data transmitted between a server and an endpoint through these ports will be transferred over your network.

How to connect to WebRTC conference in your browser

For correct operation of WebRTC application the website is required to have HTTPS certificate. WebRTC standard usually uses random UDP ports ranging from 1024 to 65535. Therefore, you will need to open this range on NAT for successful WebRTC operation. Please note that our technical support experts can help you narrow this range if required.

How to open a port?

Refer to your OS or network equipment documentation, or contact a network technician.
