Abstract
A cordless station is operable in a local mode when it is in a local area and in a global mode when it is outside of the local area. The cordless station is assigned a telephone number of a cellular mobile telephone network (CMTN) for establishing a connection therewith when it is operating in the global mode. A memory is provided for storing the cellular telephone number. A controller is connected to a public switched telephone network (PSTN) to receive an incoming call and forwards it to the cordless station when the latter is operating in the local mode, and operates a telephone answering unit to record a message of the call if the cordless station is operating in the global mode. When a message is recorded, the controller originates a call to the PSTN using the telephone number stored in the memory to establish a connection through the PSTN and CMTN networks to the cordless station operating in the global mode. A prerecorded announcement is then sent to the cordless station via the established connection indicating that a message has been recorded in the telephone answering unit. Preferably, the controller then operates the telephone answering unit to reproduce the recorded message and transmits it to the cordless station.
