Strange!
Nevertheless there is no need to drop 100 as 100 is never relayed.

Well, fr_timer also has to be disarmed when fr_inv_timer is armed right ?
So any provisional (100-199) disarm fr_timer and arm fr_inv_timer.
But you have not to drop it in reply_route.
In my case, the reply_route I set drops any provisional < 180.
This means that the 100 response will not make tm module switch fr_timer
to fr_inv_timer as it would be if not dropped.
Well this is not a problem, I only dropped provisional from 101 to 180,
and all went back to normal.
Since 100 is not forwarded (because of t_relay already generated one),
this makes no difference for end users.
I did not expect drop() statement to change anything for timers.
Thanks.

Hi,
In my openser, I had to not relay any provisional which is < 180.
I used drop in reply route to do this.
No provisional < 180 is sent to caller.
Unfortunately, dropping 100 seems to make the transaction module not
disarming its fr_timer.
100 is disabling the retransmission timer. fr_timer is the duration to
wait until a final response is received, not related to retransmission
and 100 reply.
Cheers,
Daniel
