Hey all,
I'm trying to find the best way for settings a timeout for the 'ringing' stage of a call - meaning - I would like to wait for 20 seconds between receiving status 180 / 183 / early media from the remote end and 200, if I fail to receive the expected response in this timeframe - call should be dropped. Most of the documented timeouts I saw count between the first invite to any of the aforementioned stages - but I'm actually looking for the opposite.

Hi Edward,
You can achieve this by manipulating the fr_inv_timer (timer to final dispositive response for the transaction):
https://kamailio.org/docs/modules/5.5.x/modules/tm.html#tmp.p.fr_inv_timer
The secret ingredient is to reset it in an `onreply_route` only once you have received a 180/183 response:
https://kamailio.org/docs/modules/5.5.x/modules/tm.html#tm.f.t_set_fr
e.g.
-------- onreply_route[MAIN_REPLY] { …
if(t_check_status(“180|183”)) t_set_fr(20000); } --------
