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).
