ABSTRACT:
When an incoming call is received via a telephone line in an automatic answering/recording mode, a response message stored in a recording memory is read out by a burst signal processing section at the timing of expansion processing for restoration of reception speech data, and a message sent from a caller is written in the recording memory at the timing of compression processing for generation of transmission speech data, thereby providing a simple digital radio telephone apparatus capable of performing a simultaneous answering/recording operation.
