Hello All,
We use registrar servers (call them A,B) for TLS connections from clients and a
central routing proxy (P) that authenticates and manages all call routing.
On INVITE, P uses lookup(“location”) and handle_uri_alias() to route the INVITE
to A or B depending on the AOR from REGISTER.
In failure_route I’m trying to send INVITE to a voicemail URI at host (V),
using alias_db_lookup to retrieve it and sending with t_relay(). However,
despite showing V as the host in the URI, the message is sent to A (or B) as if
the handle_uri_alias is still in effect.
I’ve tried calling revert_uri() before the alias_db_lookup(), but this doesn’t
seem to help. Is there a way to reset the uri_alias?
The failure_route (simplified) looks like this:
failure_route[1] {
if (method == "INVITE") {
revert_uri();
if (alias_db_lookup("dbaliases")) {
t_relay();
}
}
}
I have also tried using t_relay(“$rd”, “$rp”) after confirming (by logging)
that the uri contains the desired values, but kamailio failed to start, with
this error logged:
ERROR: tm [tm.c:672]: fixup_hostport2proxy(): TM
module:fixup_hostport2proxy: bad port number <$rp>
Any suggestions?
Best regards,
Dave.
