Example kamailio.cfg t_check_trans() - sr-users

31 Dec 2015

Hi there,

The example config that Kamailio ships with contains this block of code in request_route:

# handle retransmissions
if(t_precheck_trans()) {
     t_check_trans();
     exit;
}
t_check_trans();

I am not fully understanding the requirement for either of the t_check_trans() here. As
far as I can see from the documentation, t_check_trans() returns a boolean value and does
not modify any data internally.

Can anyone help me find out what the relevance of the t_check_trans() calls is?

Thanks
