If you want to have a shared registration database, you might want to 
look into the db_mode 3 mode of the usrloc module [1].

registered users, and also you'll run into some NAT issues.
Rather than actually sharing the DB, I'd suggest looking into SIP 
replication of the Register requests, alongside with proper handling of
