If lcr is based on longest prefix, Pete could just use a little logic to 
implement longest match with alias_db_lookup (his original question). I store 
either a full number, a 10 number block or 100 block (by leaving off the last 
1 or 2 digits) and do the following:

$avp(callednumber)=$rU;
if(!alias_db_lookup("dbaliases"))
{
	strip_tail(1);
	if(!alias_db_lookup("dbaliases"))
	{
		strip_tail(1);
		if(!alias_db_lookup("dbaliases"))
		{
			$rU=$avp(callednumber);
		}
	}
}

If you give bigger numberblocks to endusers just add a level (of make a decent 
loop that checks the remaining length of $rU).
