Abstract
A cellular telephone network comprising an exchange (101) and a voice messaging center (102) connected to the exchange, the exchange being connectable to a plurality of cellular telephones (103), each having an associated voice mailbox (VM1) at the voice messaging center (102), the exchange (101) being operable in the event of failure to connect a caller to a desired telephone (103) to divert the call to the voice messaging center (102) which can record a message from the caller in the associated mailbox (VM1). When such a message has been stored, the VMC transmits a "message waiting" flag for that telephone to the exchange (101). The exchange (101) transmits a "message waiting" signal to the telephone when it registers with a cell of the network, and/or if it initiates an outgoing call.
