发明名称 System for providing emergency voice mail service
摘要 The system for providing emergency voice mail service includes two components: a first component that informs a calling party that emergency voice mail service has been activated due to an interruption in telephone service provided by the affected local exchange(s), and a second component that provides emergency voice mail service to customers who are displaced from their residences or simply affected by the service outage. The calling party that wishes to leave a message or the customer whose service is interrupted and wishes to listen to their messages calls a nationwide toll free number and is routed to the Emergency Voice Mail System. The caller is asked to enter the telephone number of the customer who is out of service and then can enter a predetermined code to leave a voice mail message or retrieve a voice mail message for the wire-line or wireless customer who is out of service.
