Persistent connection


Note: This article applies to PureCloud Embeddable Framework, PureCloud for Chrome, PureCloud for Firefox, PureCloud for Salesforce, and PureCloud for Zendesk.

Persistent connection speeds up the processing of calls by keeping WebRTC phone connections open. If your administrator enabled persistent connection in PureCloud, after your first call (inbound or outbound), the client establishes a WebRTC phone connection. After the call ends, the client leaves the WebRTC phone connection open. With subsequent incoming calls, the client instantly passes the call to you using the existing connection. 

Note: Because persistent connection establishes a WebRTC phone connection, as long as the persistent connection is active, network traffic continues, and your microphone remains live.

You can quickly see in the client whether your phone has a persistent connection. Click Arrow  in the upper-right corner of the client. If your phone has a persistent connection, then a phone icon inside a circle appears in the client next to the name of your phone. Status list

Persistent connections end in the following situations:

  • After a specified period of inactivity.

    Unless your administrator changes the default timeout for persistent connection, any persistent connection ends after 10 minutes of inactivity (no incoming or outbound calls). If the persistent connection times out, the client re-establishes persistent connection after the next call connects.

  • When you log out of the client.
  • When you manually end the persistent connection.

    You can manually stop a persistent connection at any time.

    Warning: Do not stop a persistent connection while you are connected to a call. Otherwise, the client disconnects the call.
