Call Flow Example

The UAS obtains the value from the Session-Expires header field in a 2xx response to a session refresh request that it sends.

Proxies and UACs obtain this value from the Session-Expires header field in a 2xx response to a session refresh request that they receive.

Once the session timer runs out, the Oracle® Enterprise Session Border Controller sends a BYE to both the UAC and the UAS to clear the session.

Enable this feature by adding the session-timer-support option to the sip config.
