Abstract
A 1st telephone apparatus comprises a transmission system for transmitting a transmission voice SIG to a network, a receiving system for receiving a reception voice SIG from the network, a recording system for generating a recording SIG derived from the voice SIGs from the transmission and the receiving system, a memory for storing and reading the recording SIG, and a switch for playing back the reception voice SIG in a communication mode and playing back the recording SIG from the memory in a playback mode. Coding and decoding may performed by a single DSP through a time division manner. A 2nd telephone apparatus comprises a transmission and receiving systems, 1st and 2nd switches, a memory circuit, and a voice presence detector for detecting the presence of the voice SIG of the transmission system, the 1st switch stores the voice SIG from the voice SIG from the transmission system prior to the voice SIG from the receiving system. The 2nd switch provides a playback from the voice SIG from the network directly and from the memory circuit. The 2nd telephone apparatus may further comprise a frame condition detector for detecting a frame condition, a data adder for adding data indicative of the frame condition to reception SIG, and a memory control circuit. The memory control circuit inhibits recording according to the frame condition.
