[OpenSIPS-Users] RURI Modification for NATed endpoints after en ENUM Request

[Kevin Mathy]

Hi Bogdan,

Thanks for those informations, but I already know them :-)
I've attached my script to this mail, so you can take a look at what I've
done.

Also, here is the part of the code calling the script :


route[enum] {
>     t_on_reply("reply");
>     if (enum_query("asbc2.e164.local."))
>     {
>         xlog("L_INFO","$ci Sending INVITE to customer / ENUM\n");
>         if(!serialize_branches(1))
>         {
>             xlog("L_ERR", "$ci SERIALIZE_BRANCHES Failed\n");
>         }
>         next_branches();
>         t_on_failure("failenum");
>         xlog("L_INFO", "$ci ENUM lookup returned <$ru>\n");
>         xlog("L_INFO", "$ci ENUM lookup returned rd : <$rd>\n");
>

>     if(is_avp_set("$avp(newRuriDomain)"))         {
> #xlog("L_INFO","$ci New RURI Domain = $avp(newRuriDomain)\n");
> #xlog("L_INFO","$ci New RURI Port = $avp(newRuriPort)\n");            $rd =
> $avp(newRuriDomain) + ":" + $avp(newRuriPort);             xlog("L_INFO",
> "$ci We modified rd : <$rd>\n");        }*
>         uac_replace_from("sip:$fU@*XX.XX.XX.XX*");
>         uac_replace_to("$ru");
>         if (t_relay())
>         {
>             xlog("L_INFO", "$ci t_relay done <$ru>\n");
>         }
>         else
>         {
>             xlog("L_INFO", "$ci t_relay problem \n");
>         }
>         exit;

Please note : I've intentionally hidden the IP's in both scripts. And the
script may not be perfect, as it's only there to show you what I'd like to
do :-)


So, this configuration is working well, but is there a way to not use the
"perl method" and simply use some methods of the registrar module, or any
other ?

If you need further informations to understand what I want to do, feel free
to ask me ;-)

Thanks a lot,
