The RFC says estimated round trip time or 500 ms for T1. We use the
result from the OPTIONs request as the estimated round trip time to be
able to speed up failure situations instead of waiting up to 64*500 ms.

If qualify is on and in sip.conf t1min is set to 500ms, it will not
use calculated round trip time. <br>

(dialog->timer_t1 = peer->lastms < global_t1min ? global_t1min
: peer->lastms;)<br>

t1min is usefull for some devices which is not able to response as
quickly as calculated round trip time (grandstream gxp2000 had
problems) <br>
