transaction occurs beforehand. The default value is

The SIP Session Timer extension enables SIP sessions to be
periodically “refreshed”through a SIP request (UPDATE, or
re-INVITE). Once the session interval expires, if there is no
refresh through the UPDATE or re-INVITE message, the
session is terminated.
