SYSTEM AND METHOD FOR DEVICE AVAILABILITY SIGNALING

摘要

A system and method for receiving and storing telephone status data (busy, off, free) of a contact, and transmitting such data over a data network to telephones that include such contact on contact list. An indication of the status of the contact may appear in association with the contact's other data on the contact list so that a user of the telephone storing the contact can determine if the contact is available without dialing the contact.
