I started travelling and this one got out of my sight. I wanted to check if the event route is executed only for transactions started locally, it is also for hop-by-hop ACKs generated on failed received+forwarded INVITEs.
Same question would be also for the CANCEL requests (https://github.com/kamailio/kamailio/commit/faca8e7a20255d90a4786fd4043005ea... and https://github.com/kamailio/kamailio/commit/ccc106922802213253f03f181d10fe83...), is the event route executed only for CANCELs of locally initiated INVITEs, or for all hop-by-hop CANCELs?
If the event route is executed only for ACK/CALCEL of locally initiated INVITEs, then I am fine with no new modparam, but if it also executed for cases of the hop-by-hop ACK/CALCEL of received+forwarded INVITEs, then I consider that the impact can be significant for instances with high SIP traffic and I would prefer to be able to control via a modparam.
