Abstract

A telephone system having a voice mail system and supporting virtual telephone numbers for called parties. A switching system in the telephone system has a plurality of telephone lines connected to the switching system with each telephone line having a telephone number. Each called party in the system has a virtual telephone number that is not associated with a particular telephone line. When a called party desires to receive incoming telephone calls over a telephone line, the called party performs a log-in from the telephone line. The log-in causes the switching system to extend all calls specifying the virtual telephone number of the called party to the telephone line. If the incoming call is not answered, the call is extended to a voice mail system which records a message and stores the message in a voice mail box associated with the virtual telephone number of the called party. The called party then performs a log-out when the called party no longer desires to receive telephone calls at the telephone line and all incoming calls are extended directly to the voice mail system.
