The video conferencing server can check accessibility of network resources via 'ping' command. To do it, enter the IP address or DNS into the address field and click Validate. You will see the result in the output field.

If you enter an incorrect address in the input field, the output field will display an error from the server.

Using 'traceroute' command


To determine the data packets route in TCP/IP networks and the path length, you can use the 'traceroute' command. To proceed, complete the steps mentioned in the previous command.

Traffic capture

TrueConf MCU is equipped with a network analysis tool that can capture and save incoming and outcoming data packets. To start capturing, click Start. When you stop log collection, a table with a list of files will be displayed below, indicating the time and file size. You can save the file by clicking /mcu/media/save_icon/en.png and delete it using the /mcu/media/delete_icon/en.png button.

TCP/IP ports

To configure audio and video transmission protocols, go to the TCP/IP ports tab. You can also specify port ranges for the following protocols:

  • BFCP

  • H.245

  • RTP.

This section also enables you to specify the size of RTP packets and select the ports for SIP and H.323 connections.

You can set up the priority of data streams according to the DSCP (opens new window) protocols:

  • DSCP audio is for audio traffic

  • DSCP video is for video traffic

  • DSCP other is for other traffic, e.g. remote PTZ camera control.

The larger number you set, the higher priority will be given to the selected type of transmitted packets.

Network interfaces

In the Network interfaces tab, you can check the server system name and its MAC address. It is also possible select an IP addressing mode (static or DHCP). If the static mode is selected, the following parameters have to be specified:

  • IP address

  • Subnet mask

  • Gateway

  • Primary DNS server

  • Secondary DNS server.


In this section you can configure video encoding and storage settings:

  1. Set the maximum size of media file storage.

  2. Select an encoding profile for the primary video stream.

  3. Select an encoding profile for the secondary video stream.

  4. Set the bandwidth for the secondary video stream (will be calculated as the percent of the total bandwidth allocated for both primary and secondary streams).

  5. Set the time interval for shuffling or alternating participants in the video window (available only when selecting a layout supporting shuffling).

  6. Select a video scaling mode for layout windows.

  7. Enable/disable avatar display in the fixed layout window (will be displayed if a participant has not yet joined the conference or has turned off the camera).


To configure call settings, go to the Calls menu.

  1. You can enable calls via SIP/H.323 protocols on the video conferencing server.

If the Use H.323 box is unchecked, you will be able to connect to a conference held on TrueConf MCU only via SIP protocol.

2. Check if a particular protocol is enabled.

3. Specify the call priority:

  • Address book first
  • Gatekeeper first

4. Set up the order of using SIP/H.323 protocols when you call users (if you specified both protocols in the address book).

5. Specify a name for the video conferencing server to be displayed on the conference participants' monitors.

6. Enable remote camera control of conference participants (if it is supported by participants' hardware).

7. Enable noise cancellation.

8.Enable automatic gain control (AGC).

9. Enable avatar display for non-video participants.

To ensure better performance, you should perform calibration each time when the server hardware is changed or when a major update of TrueConf MCU is released (e.g., an update from v 1.2 to v.1.3). This will allow you to increase the maximum number of users simultaneously participating in a conference and improve audio and video quality. Calibration also affects the correctness of the display of server statistics.

To perform calibration, go to the Administration → Calibration section and click Start calibration.

In the lower right corner there will be the calibration progress bar. You can end this process by clicking on the Stop button. During calibration TrueConf MCU will automatically rate the server performance in different modes and with different audio and video codecs.


All active conferences will be automatically ended when calibration starts. You will not be able to hold meetings until calibration is completed or cancelled. The calibration may take a few hours depending on the server performance.
