[Freeswitch-users] INVITE and hangup in the middle of a call

But isn't that based on the session-timeout param which defaults to 30
min?  My re-invites occur much sooner than 30 min into a call.  Or does
session-timeout param only control sessions initiated by FS while incoming
sessions use the minimum-session-expires param if it's not explicitly
passed by the session initiator?
