Hello, question related to sst module.
Suppose a use case on which the UAC (A) offers during the invite 
Session-Expires : 4000, MIN-SE :90
UAS (B) configured sessions-expires=5000s but responds : "Session-Expires : 
4000, refresher=uas" to match UAC's request.
That means at roughly 2000 seconds the refresher (UAS (B) in our example) must 
send a re-invite request to keep the dialog alive. (halftime as expected #RFC 
4028#)
In the middle of both UAS and UAC an opensips box acting as a proxy running sst 
module and min_se configured on default value (1800s) (no sstCheckMin)
Opensips won't change anything related to the use of session times headers 
since the UAC requested it already, but still will set the dialog expiry date 
to initial invite time + 1800s, expecting a re invite before timeout, But since 
both UA agreed on 4000s SE, the reinvite will happen at +2000s. This will cause 
opensips upon reaching dialog lifetime (1800s), to trigger BYEs both ways 
hanging up the call.
Is this normal behavior ?

Thank you.
