Tech requirements for Telephony module

If you have any problems with Bitrix24 Telephony, please check the following requirements:

  1. Internet connection speed - no less than 128 Kbps (Kilobits per second) for each conversation.
  2. Recommended Internet browsers:
    • Mozilla Firefox;
    • Google Chrome;
    • Edge;
    • Safari.
    Read more about supported browsers in the Voximplant Web SDK guide.

    We don't guarantee the correct functioning of Bitrix24 Telephony if you use any other browser.

  3. If you're using Bitrix24 desktop app for calls, it should be version 7 or newer.
    WebRTC technology uses https protocol. Thus, you need to get a trusted SSL certificate to make voice calls and video calls via desktop app. Self-signed certificate may cause incorrect work. This applies to Bitrix24 Cloud version with own domain and Bitrix24 Self-hosted version.
  4. To make calls, you need a headset or configured SIP-phone connected.
  5. If you use SIP phones and "To everybody" type of call distribution, incoming calls cannot be transferred to more than 10 phones (devices). This is Voximplant's limitation.
  6. Local network settings.
    You need to open:
    • Ports:

      For calls from a browser: 443 TCP, 3478 TCP/UDP, 8000-48000 UDP.

      For calls from a SIP device: 5060 TCP/UDP, 3478 TCP/UDP, 8000-48000 UDP.

    • You can get Voximplant IP addresses automatically by using API.
  7. Voximplant supports G711 (u-law and a-law), Opus, ILBC, H.264, VP8 codecs.
  8. Call quality test.
  9. Follow this link to test call quality: https://echo.voximplant.com/iframe.html

    This test helps you check:

    • Browser version;
    • SDK Load;
    • Access to microphone;
    • Authorization;
    • Connection quality.

    If any problems are found during the test, you will be offered possible solutions. Then you can start this test again to make sure everything works fine.

  10. Ad blocking software used in your browser or antivirus can also block calls. Just add your Bitrix24 account address and call quality test website to exceptions in this software.
