Session Expiration 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.
Min-SE The minimum session expiration (in seconds). The default value is 90 seconds.
