Description

This article explains the default timeout settings for SIP protocol sessions on SSR devices and how they function.

Solution

  1. Navigate to Configuration → Session Type → SIP on the SSR device.

  2. Default session timeout for SIP is: 3600000 milliseconds (60 minutes).

Notes:

  • Timeout values are defined in milliseconds.

  • The inactivity timer frees SSR resources if a session remains idle for the configured timeout duration.

  • The upper limit is an unsigned 64-bit integer (0–18,446,744,073,709,551,615).

  • SSR refreshes the session timeout whenever a new packet is seen in the existing flow. If no packets are received on either side, the session will time out automatically.
