Hi!
1. I never used subst so I do not know how it is supposed to work 2. Mangling To is often not needed, changing RURI is usually sufficient 3. If I need to change the To header, eg. for tsting purposes, I just delete the existing one and create a new one: remove_hf("To"); append_hf("To: sip:$dbr(alias_name=[0,0])@$dbr(alias_domain=>[0,0])>\r\n");
regards klaus

Thank you for the answer, Klaus
I have tried your way(commented my subst and added your rows), so now it looks like this:
failure_route[2] { if (!t_is_canceled() && t_check_status("486|408")) { $avp(alias_seq)=$avp(alias_seq)+1; xdbg("HERE WE ARE! $avp(alias_seq)\n"); revert_uri(); sql_query("main", "select username from subscriber where alias='$tU' and alias_seq='$avp(alias_seq)'", "alias_name"); sql_query("main", "select domain from subscriber where alias='$tU' and alias_seq='$avp(alias_seq)'", "alias_domain"); if ($dbr(alias_name=>rows) != 0 && $dbr(alias_domain=>rows) != 0) { subst_uri('/^sip:.*@.*$/sip:$dbr(alias_name=>[0,0])@$dbr(alias_domain=>[0,0])/'); # subst('/^To:.*sip:.*/To: sip:$dbr(alias_name=[0,0])@$dbr(alias_domain=>[0,0])>\r\n/'); <--COMMENTED OUT THIS ONE remove_hf("To"); # <--ADDED THIS ONE append_hf("To: sip:$dbr(alias_name=[0,0])@$dbr(alias_domain=>[0,0])>\r\n"); # <--ADDED THIS ONE sql_result_free("alias_name"); sql_result_free("alias_domain"); setflag(10); if (!lookup("location")) { switch ($retcode) { case -1: case -3: t_reply("404", "Not Found"); exit; case -2: exit; } } append_branch(); route(5); } } if (is_method("INVITE")) { unforce_rtp_proxy(); }
}
route[5] { if (!t_relay()) { sl_reply_error(); } exit; }
So the code now supposed to delete "To: <sip:ncm0000b@domain.comsip%3Ancm0000b@domain.com
"
and to append "To: < sip:ncm0000a@domain.com sip%3Ancm0000a@domain.com>"
But with ngrep i can see: To: <sip:ncm0000b@domain.com sip%3Ancm0000b@domain.com>.Date: Tue, 08 Jun 2010 09:40:10 GMT.
With timestamp, which seems to me to be unusual.
So maybe it's impossible to rewrite "To" header from failure_route for some reason... (For example according to RFC)
Actually my phones ring, and everything works fine, I am just interested with this behavior of Kamailio.
Thanks again for your reply.
Sincerely yours, Kosilov Fedor.

remove_hf("To"); append_hf("To: sip:$dbr(alias_name=[0,0])@$dbr(alias_domain=>[0,0])>\r\n");

yes.

The timestamp is the next header. Thus, somehow the CRLF gets lost between To header and Date header?

AFAIK it should be possible.
I just tested with kamailio 3.0 and it works fine.
Try something simpler, e.g: append_hf("To: sip:ncm0000a@domain.com\r\n");
