description	The utility model relates to a telephone caller, which comprises a signal input circuit, a two audio decoding and encoding circuit, a decoding circuit, a sound generating circuit and a delay circuit which are connected in sequence, wherein, the signal input circuit plays the action of simulating off-hook and on-hook; signals of the delay circuit are fetched from the sound generating circuit and are fed back to the signal input circuit. The utility model has the advantages that the utility model can obtain normal conversation after off-hook as well as confirm the person called by the calling party according to telephone ringing tone, and mistaken touch key can not influence the conversation. The line connection is also convenient.
