Hi Jeff,

It is more or less the same. user_preferences gives a bit of a more flexibility as you have the additional type field , while the db_alias does not have (there is only one mapping from alias to user) - but you can use different aliasing tables.

Also, the user_preferences support non-SIP keys (to look for a new value) - like a user ID -, while db_aliases use a SIP uri key.

Using 1.10. Is there any issues using db_alias for forwarding as opposed to user_preferences?

Thanks
