<p class="MsoNormal" style="background:white"><span lang="EN-US" style="color:#222222;mso-fareast-language:FR">Hello, question related to sst module.<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span lang="EN-US" style="color:#222222;mso-fareast-language:FR">Suppose a use case on which the UAC (A) offers during the invite Session-Expires : 4000, MIN-SE :90<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span lang="EN-US" style="color:#222222;mso-fareast-language:FR">UAS (B) configured sessions-expires=5000s but responds : “Session-Expires : 4000, refresher=uas” to match UAC’s request.<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span lang="EN-US" style="color:#222222;mso-fareast-language:FR">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#)<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span lang="EN-US" style="color:#222222;mso-fareast-language:FR">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)<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span lang="EN-US" style="color:#222222;mso-fareast-language:FR">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.<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span lang="EN-US" style="color:#222222;mso-fareast-language:FR">Is this normal behavior ?<o:p></o:p></span></p>
