Summary: New function registered_from in module registrar
Initial Comment:
I have a requirement to only accept requests from UAs that are currently
registered. And the ip:port from the request must be the same that was used in
the registration (received_avp).
So I have written a function registered_from (based on function registered)
that will receive parameters location, AOR and URI-received (all required), and
will return true if:
- string received="scheme:ip:port" is found inside ucontact->path
or
- ucontact->received equals URI-received
Examples of use:
$var(received) = "sip:" + $si + ":" + $sp;
if(!registered_from("location", "$fu", "$var(received)")) {
sl_send_reply("404", "Request not from registered UA");
exit;
}
if(!registered_from("location", "$fu", "$hdr(User-Received)")) {
sl_send_reply("404", "Request not from registered UA");
exit;
}
I have generated the patch from branch 1.6 which is the one I am currently
using but I can regenerate it from trunk if necessary
regards,
Takeshi
