Hello,

given that this question was asked few times in the past, I put it in the FAQ:

- https://www.kamailio.org/wiki/tutorials/faq/main#how_is_the_sip_request_retrans

Hope the explanation there is clear enough, if not ask more here and I will complete with further details.

Cheers,
Daniel

Hi.

In the below part from kamailio.cfg, why didn't we just exit if t_precheck_trans returns true ?

Why did we run t_check_trans, although there might be another process already running the other t_check_trans ?

# handle retransmissions

if (!is_method("ACK")) {

if(t_precheck_trans()) {

t_check_trans();

exit;

}

t_check_trans();

}
