Hello. I have found another important thread "Catching internally generated BYE event & other" regarding this goal. Alex, Do you mind to share how did you catch the internally generated BYE? (by just reading the thread I can't know if you really did) As far as I understand, the event_route could be used for this (accounting) but specially acc_db_request() does not seem to work. Maybe I am missing something basic or there is other approach to reach this target. Thanks for any tip, Alexandre.

Why acc_db_request() doesn’t work on event_route?

I am using GIT version from Kamailio branch 3.1. http://www.mail-archive.com/users@lists.kamailio.org/msg01411.html Unfortunately, in the archives, there’s no solution for that. Regards, Alexandre
