Technical requirements for video calls

There are some technical requirements that have to be met to be able to perform video calls:

  • Video calls are available in the Google Chrome version 80+, in the Bitrix24 Desktop app and the Mobile app. When calling a colleague with an older version of the browser, there will be the corresponding notification shown.
  • For the correct functioning of internal calls, access must be open for addresses and ports that are used for calls between employees:
    Ports:

    Open port 3478 (TCP and UDP) for STUN and TURN protocols.

    If peers are not able to establish a direct connection, TURN-server can act as a proxy for RDP connection (UDP ports 16384-32767)

    You can get the Voximplant IP addresses using the API.

  • To perform video calls, you need to have an Internet connection speed depending on the video quality (VP8 codec):
    • 720p, 30 fps: 1-2 Mbps
    • 360p, 30 fps: 0.5-1 Mbps
    • 180p, 30 fps: 0.1-0.5 Mbps

    Video quality is changed automatically depending on the connection speed.

    Use the formula below to figure out what Internet connection speed you need to have to perform a group video call between employees:

    from 0.1 to 2 Mbps * [number of users in a group video call] * 2

  • Bitrix24 On-Premise Edition users have the limit of 24 employees in the group to make a group video call, but need to meet the following requirements:
    • have an active Bitrix24 On-Premise license;
    • have a Telephony module installed;
    • Use SFU Voximplant server for video calls option needs to be enabled in the settings of the Instant Messenger module (im) version 20.0.887 or higher.
