发明名称 METHOD AND APPARATUS FOR MONITORING TELEPHONE STATUS
摘要 The monitor is for monitoring the status of a first client telephone, and for sending this status information via a central server to an authorized second client telephone. The central server stores a database of registered client telephones and corresponding client telephones that the client may monitor. A user of a registered client telephone monitors in real time the telephone status of registered friends, family, or co-workers that have agreed to be monitored by the user.
