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.

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