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

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.com<sip%3Ancm0000b@domain.com>
"
and to append
"To: <
sip:ncm0000a@domain.com <sip%3Ancm0000a(a)domain.com>
"
But with ngrep i can see:
To: <sip:ncm0000b@domain.com <sip%3Ancm0000b(a)domain.com>>.Date>.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:

New subject: Strange behavior when rewriting "To" header from failure_route (kamailio - 3.0.2)

yes.

The timestamp is the next header. Thus, somehow the CRLF gets lost
between To header and Date header?
So maybe it's impossible to rewrite "To" header from failure_route for
some reason... (For example according to RFC)
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");
