Multi-card intelligent telephone traffic recording device and system

Abstract

The invention discloses a multi-card intelligent telephone traffic recording device and system. The invention comprises a power supply, a main control chip, a 4G module, a telephone line user module,an SIM card switching control unit and a voice switching module. The power supply supplies power to the main control chip, the 4G module and the telephone line user module. The main control chip controls the 4G module to call out; and simultaneously plays voice. Meanwhile, the telephone line user module is controlled to ring a landline phone, and record a call. The voice switching module is used for switching voice. The 4G module and the telephone line user module are connected; the 4G module comprises a plurality of SIM cards, when one SIM card breaks down or is short of time, the main control chip controls the SIM card switching control unit to be switched to other SIM cards, office work can be achieved only through three interfaces, the layout is simple, the product error-tolerant rateis greatly increased, and the station efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multi-card intelligent traffic recording device and system. Background technique [0002] A telephone is a device that can make calls. With the development of technology, telephones with recording functions have also appeared. Most telephones are 16-way or 32-way equipment, which are connected to the public switched telephone network. Ordinary telephones, each landline must be equipped with a computer and telephone lines, with few interfaces and poor compatibility, resulting in a complicated layout, and one voice line corresponds to one SIM card, which has a low fault tolerance rate. Once a failure occurs, the station will be shut down. affect work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a multi-card intelligent traffic recording device and system, which has a simple layout and a high fault tolerance rate, t...
