Hi, Maxim!
The code you are using now should do what you request. t_newtran()
returns 0 for retransmissions, therefore for the second message
(retransmission) that will run the script, t_newtran() will immediately
absorb the message and return without executing any further instructions.
Best regards,

P.S. python_exec("www_authenticate") does not do any magic here, it's
just figures out the right domain to use based on some business rules
and then calls www_authenticate() with that parameter.

Hi guys,
We are underway to migrate from ancient SER-2.0.0 to more modern
OpenSIPS and one of the question that is still in my TODO list is
implementing transactional processing of the REGISTER requests. In
the old SER we had something along those lines:
route[3] {
# Ensure that all incoming messages contain auth info
xlog("L_INFO", "processing %rm received from %si:%sp");
if (!t_newtran()) {
sl_send_reply("500", "could not create transaction");
break;
};
if (!python_exec("www_authenticate")) {
xlog("L_INFO", "challenging %ct");
if (is_avp_set("s:digest_challenge")) {
append_to_reply("%$digest_challenge");
};
t_reply("401", "Unauthorized");
break;
};
[....some more unrelated processing and checks...]
xlog("L_INFO", "saving contact %ct into the database");
save_noreply("location");
if (is_avp_set("s:contact")) {
append_to_reply("%$contact");
};
t_reply("$code", "$reason");
}
The idea here is to avoid possibly costly DB lookup and other
checks on each possible re-transmit. What would be the proper way
of doing this with the OpenSIPS 2.1? Or if it's not possible to
replicate such scheme, what would be the best way to implement
this which to get the change accepted into the OpenSIPS mainline?
Any ideas, pointers, hints are greatly appreciated. Thanks in advance!
-Maxim
