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
