Hi all,
I'm playing around serial forking with avpops module. My goal is to have one PSTN number mapped to N voip number; so, when the first voip number is busy, OPENSER catch 486 reply and then try with the second AOR and so on. But here raise the problem: the OPENSER forward the reply upstream with a code 407 Proxy Auth Required and the PSTN GW send his ACK and all stop here.
Below ther's a snippet of mi openser.cfg:
modparam("avpops", "avp_aliases", "serial_fork=i:665")
[..skipping..]
#if RURI is to a voip user:
avp_db_load("$ruri", "$serial_fork");
avp_print();
avp_pushto("$ruri","$serial_fork");
lookup("aliases");
if lookup("location") {
t_on_reply("1");
t_on_failure("2");
t_relay();
break;
};
onreply_route[1] {
if (t_check_status("486")) {
t_on_failure("2");
break;
};
}
failure_route[2] {
if (t_check_status("486")) {
# delete the first element of the list (if any) and pass to second from list
avp_delete("$serial_fork");
if (avp_pushto("$ruri", "$serial_fork")) {
append_branch();
avp_delete("$serial_fork");
t_on_failure("2");
t_relay();
}
}
}
My DB entries are:

Do you have a suggestion to resolve this problem? Why OpenSer send upstream 407 after received 486 Busy Here and not try to send a new INVITE to voip user with new R-URI?
Many thanx,
Verbal
