route {
route(2);
if(!method=='ReGISTER') {
record_route();
};
if(uri==myself)
{
.....
......
....
}
route(1);
}
route[1] {
log("Testing-------> route[1] \n");
if (subst_uri('/(sip:.*);nat=yes/\1/')){
setflag(6);
};
if (isflagset(5)||isflagset(6)) {
route(3);
}
if (!t_relay()) {
sl_reply_error();
};
exit;
}
route[2]{
log("Testing-------> route[2] \n");
# force_rport();
