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?
t_check_trans() is used to detect retransmissions. If a retransmission
is received, then the last reply (if any) needs to be sent back, then
t_check_trans() does an 'exit' internally.
Cheers,
Daniel
