I am using dialog in my script,
here is the part of main function
# apply transformations from dialplan table
dp_translate("0","$rU/$rU");
# route calls based on prefix
if ( !do_routing("1","W",,"$var(rule_attrs)","$var(gw_attrs)") ) {
send_reply("404","No Route found");
exit;
}
$acc_extra(gwid)=$avp(gw_id);
t_on_failure("GW_FAILOVER");
do_accounting("db|log","cdr|missed",);
#NAT
if (isbflagset(NAT)) setflag(NAT);
#NAT
#TOPOHIDE
toopology_hiding("UC");
#TOPOHIDE
route(RELAY);
}
