Hello,
The approach you're taking seems good, and it should definitely work.
Do you receive any errors in the OpenSIPS logs ? If you make a SIP trace
( ngrep / tcpdump ) on the OpenSIPS machine, do you see the INVITE
message getting out of OpenSIPS ?
If you don't see the package being sent out even on the OpenSIPS
machine, then it means that somehow your script doesn't forward that
request, but drops it ( because ngrep on the OpenSIPS machine excludes
any firewall issues - ngrep gets in even before the local iptables
output chain ).

Hello Guys,
Im trying to implement a system to manipulate DID's, the forward
for external address is ok, but in trying now to do the same with
a user that is registered
i create a new table where i have the did, the account and the
destination, if the destination is null so the opensips will check
the account on the location table.
basically i have this
if(!$avp(91)){
xlog("Did nao encontrado");
sl_send_reply("404", "Not Found");
exit;
}else{
xlog("Did encontrado,
seguindo regras para utilizacao em location");
$ru = "sip:" + $avp(91) +
"@IP_ADDRESS:5060";
xlog("Novo destino $ru");
}
the avp(91) is the user account, the same that the user use to
register
when in this situation, the call go trouhg the location module,
and the system find the correct address.
i have on the log the same information that i have on opensipsctl
ul show
Fazendo relay <null> -
sip:055011395010100000@IP_ADDR:5081;rinstance=0f9054bc313f0cf1;transport=UDP
below the output from ul show

But when i make the call, the ngrep show me the send of the

Below you have the invite

after the invite, i get a request timeout message
i try to create some firewall rules on the customer side but i
dont see any package, from the opensips is like the package is
beeing sended
i made a try using another machine that dont have nat and i cant
see the package in this case too.
anyone have an idea about this ?
Thanks.
