Summary: UAC module
Initial Comment:
RFC declare that SIP strings (at least From To Remote-Party-Id) can be utf8
encoded, but not all SIP terminals can correctly process that strings when thay
are out of latin charset. In this case i want special processing for that
uteminals (user-agents). For example i want enaple pass through utf8 for
terminals with predefined user agent string and clear or transform for others.
I found the way to do it in branch_route handler instead of route handler (due
to more than one terminal can be registered under same URI and they can be from
different vendors).
branch_route[1] {
$avp(s:useragent)="";
avp_db_query("select user_agent from location where
contact='$ru'","$avp(s:useragent)");
if ($avp(s:useragent)=~"SJphone") {return;};
uac_replace_from("transliterate","");
return;
}
But uac_replace_from in auc.c declared with REQUEST_ROUTE flag only. With
attached patch i can solve proplem with some utf8 buggy sip terminals.
I thing that this simple patch will be usefull.

Hi Alexei!
if you have NATed clients and you use fix_nated_register() then the SQL
query is wrong and should be
avp_db_query("select user_agent from location where contact='$ru' and
received='$du'","$avp(s:useragent)");
Further, this query is dangerous because of SQL injection, thus you should
use transformations (openser >=1.2):
avp_db_query("select user_agent from location where
contact='$ru.escape.common' and received='$du'","$avp(s:useragent)");
