Grandstream implemented SIP Session Timer. The session timer extension enables SIP sessions to be periodically “refreshed” via a re-INVITE request. Once the session interval expires, if there is no refresh via a re-INVITE message, the session will be terminated.

Session Expiration is the time (in seconds) at which the session is considered timed out, if no successful session refresh transaction occurs beforehand. The default value is 180 seconds.

The minimum session expiration (in seconds). The default value is 90 seconds.

If selecting “Yes” the phone will use session timer when it makes outbound calls if remote party supports session timer.

If selecting “Yes” the phone will use session timer when it receives inbound calls with session timer request.

If selecting “Yes” the phone will use session timer even if the remote party does not support this feature. Selecting “No” will allow the phone to enable session timer only when the remote party support this feature.
