发明名称 Method and apparatus for alerting multiple telephones for an incoming call.
摘要 <p>A system for alerting a plurality of telephones in response to an incoming call to a destination directory number. A handling switch sends a query to a centralized database requesting routing instructions, and the database returns the directory number of the plurality of telephones to be alerted for incoming calls to the destination directory number. The busy/idle status of all of the plurality of telephones is checked, and an alerting signal is sent to all idle telephones. The handling switch is notified as to which alerted telephone has an off-hook appearance first, and the incoming call is routed to that telephone. &lt;IMAGE&gt;</p>
