Hi guys,
I'm having problems about loose_route(). Opensips is routing ACK
requests to itself.
I know that posting code and traces are ugly, but I think I do not
have choices. Sorry.
Follow bellow the code regarding loose_route:
if (has_totag()) {
if (loose_route()) {
if(method=="INVITE") {
route(5); #Check authentication of re-invites
}
route(1);
} else {
if ( is_method("ACK") ) {
if ( t_check_trans() ) {
route(1);
}
}
}
}
Follow bellow the trace, 192.168.191.188 is the opensips ip address:
