keeping different indexes will add lot of complexity in synchronizing 
them on insert/update/delete, which can end up also in loss of 
performances. Other field that would need indexes are contact address, 
callid, path, if you look at the other types of lookups done in usrloc.

The aor is not necessary to be kept in order to locate the record, 
aorhash would be enough (which is unsigned int) along with ruid. Getting 
aorhash from aor is really fast, so keeping only the aor might be better 
in some situations when it is needed for other purposes.

Cheers,
Daniel
