Voice output method for ISDN communication apparatus

摘要

The method involves comparing call numbers received in an ISDN apparatus via the ISDN D-channel with numbers stored in a memory as an address. Each address includes at least one number. Voice information stored for a specific address as address information is activated and is output via a loudspeaker of the communication apparatus as a voice announcement when address is detected. Preferably, the numbers which correspond to the address are stored as address information in form of voice information. The call number of the caller is output as voice information.
