[OpenSIPS-Users] Trying to change the $ru to an address in location

[Mike Tesliuk]

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 at 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 invite, but i
dont see nothing on the other side.

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.
