Long Distance Phone Tag

https://patents.google.com/patent/US5987113A

A phone service for preventing missed connections and “phone tag” that commonly happens and, in particular, helps people contact people who are traveling is disclosed. A user registers the phonenumber at which he or she is currently located with a service controller which maintains a database of such user registrations. The user may also prioritize the identities of other users with whom he or she wishes to contact. When the service controller determines that a first user wishes to get in contact with a second user and that both users have current locations registered in the database, then the service controller will call both users and connect them to each other.
