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.
