• Firmware: 83.20.0.74 or later
• Subscription: Ultimate Plan

• You have obtained the WebSocket server address of the third-party platform for receiving the audio stream.

• If authentication is required by the third party, ensure that you have obtained the appropriate credentials.

1. Log in to PBX web portal, go to Integrations > WebSocket Audio Streaming.
2. Turn on WebSocket Audio Streaming to enable the feature.
3. Configure WebSocket audio streaming settings.

   

   1. In the Server Address field, select the protocol (ws:// or wss://) as required by the third-party platform, then enter its server address to receive the audio stream.
   2. Optional: In the Secret field, enter the authentication credentials provided by the third-party platform.
      Note: You can click to customize the option name based on the specific authentication field names required by different platforms.
   3. In the Sample Rate drop-down list, select the sample rate of the audio stream to be transmitted.
      Note: The audio streams will be sent to the third-party platform in different fixed-duration fragments according to the sample rate:

      • 8000Hz: Each fragment is 80 ms long.
      • 16000Hz: Each fragment is 40 ms long.
   4. In the Subscription Object, specify which calls will be transmitted to the third-party platform via WebSocket protocol.

      Object	Description
      Extension	Audio streams from calls involving the selected extensions will be transmitted to the third-party platform.
      Trunk	Audio streams from inbound and outbound calls routed through the selected trunks will be transmitted to the third-party platform.
      DID Number	Audio streams from inbound calls to the specified DID numbers will be transmitted to the third-party platform.
