Abstract

Providing a telephone apparatus and a PBX which can properly perform redialing including sending of a personal ID to a called telephone apparatus even in case the telephone apparatus has to input a personal ID over a DTMF signal after it has answered the call According to the invention, the input dial information is sequentially stored into a redial table. On detection of a connection signal, mark information is stored into the redial table. In case dial information is further input, the dial information is sequentially stored into storage means until the call is released. On a redial request, the dial information before the mark information out of the dial information stored in the redial table is output to the control channel of a digital communications line while the dial information after the mark information is output to the voice channel of the digital communications line after a connection signal from the digital communications line is detected.

Description

technical field [0001] The present invention relates to a telephone device such as a touch-tone telephone device and a private branch exchange (hereinafter referred to as a PBX) having a redial feature, and more particularly to a PBX. Background technique [0002] In the related art, telephone sets have been equipped with the function of storing a dial number on the telephone line and using the stored information to dial out the same number (as disclosed in Japanese Patent No. 49463 / 1989 laid open). Mentioned). [0003] But, for this related art telephone set, after the called telephone set answers the call and transfers the stored dialing information to the telephone line, a personal ID must be input by DTMF signal, and then the called telephone set answers the call Dialing information was continuously output before. It is thus impossible to receive the personal ID entered by the DTMF signal on the called telephone set after the called telephone set has answered the call....
