Without the sst_interval option, the dialogs' timeouts are 30 seconds from creation. With the sst_interval option, they're 3600 seconds, and they update to 3600 seconds in the future whenever a re-INVITE comes through (session refresh, call hold, whatever)
regardless of the Session-Expires passing through. That doesn't seem right.</div>

one side to the other. Both the UAC and UAS have full session timer support. The INVITE arrives at the proxy with Min-SE: 90 and Session-Expires: 1800. OpenSIPS' sst module has min_se=90. The dialog is created and the SST flag is set. The first problem is
the dialog lifetime is always set to the sst module's configured min_se value regardless of the Session-Expires value in the message. Is this a bug, or am I doing something wrong?</span></div>

than the Session-Expires from the message. Looking at sst_handlers.c around line 300, this should send be handled a few different ways depending on various factors, but instead the process segfaults.</span></div>
