Quick secondary-dialing method for telephone

Abstract

The invention relates to a quick secondary-dialing method for a telephone. A programmable telephone in which a memory and a microprocessor chip are built is chosen; a quick secondary-dialing program is put into the quick memory of the telephone; a telephone background is set to access a pre-dialing number; when the telephone is picked up and the handfree knob of the telephone is pressed, the microprocessor chip of the telephone switches on a communication module of the telephone; a telephone foreground waits and receives user keys and caches key a code; and after the background gets through the secondary-dialing platform, the microprocessor chip of the telephone immediately automatically sends the cached key code to the secondary-dialing platform according to a user input sequence in a dual-tone multi-frequency (DTMF) signaling mode on the background. According to the setting of the telephone with the quick secondary-dialing method, time for dialing and accessing into the platform is saved, and telephone cut-in time is greatly shortened.

Description

technical field [0001] The patent of the present invention relates to a telephone dialing method, specifically, to a telephone rapid secondary dialing method with pre-dialing set in the background of the telephone. Background technique [0002] With the development of science and technology, two-stage dialing technology has been used more and more widely. For example, the outgoing calls of IP phones, virtual switches, virtual switchboards, etc. are basically realized with the help of this technology, but the dialing process remains In the initial stage, the user manually dials the platform access number, and after the platform is connected, enters the phone number to be dialed according to the voice prompt of the platform, or appends the platform access number in front of the number to be dialed to complete a second call Therefore, there are defects such as inconvenient use and long connection time. Especially when applied to mobile phones, the connection time is too long, ...

Problems solved by technology

[0002] With the development of science and technology, two-stage dialing technology has been used more and more widely. For example, the outgoing calls of IP phones, virtual switches, virtual switchboards, etc. are basically realized with the help of this technology, but the dialing process remains In the initial stage, the user manually dials the platform access number, and after the platform is connected, enters the phone number to be dialed according to the voice prompt of the platform, or appends the platform access number in front of the number to be dialed to complete a second call process, so there are defects such as inconvenient use and long connection time

Especially when applied to mobile phones, the connection time is too long, which will undoubtedly waste the use time of customers and greatly affect the promotion and development of IP phones
