Dual-mode voice communications system

A dual-mode voice communications system, comprising a processor, and a first communication connection module, a second communication connection module, and a wireless transceiver module that are separately connected to the processor,

• wherein the first communication connection module is configured to realize a communication connection between the dual-mode voice communications system and an Internet Protocol (IP) base station, the second communication connection module is configured to realize a communication connection between the dual-mode voice communications system and an external communications device, and the wireless transceiver module is configured to realize a communication connection between the dual-mode voice communications system and a wireless terminal device;
• and
• the processor is configured to process data transmitted by the IP base station, the external communications device, and the wireless terminal device;
• wherein the processor further comprises an account processing module configured to receive account information and registration data delivered by the IP base station;
• wherein the processor is further configured to transmit a voice stream of the external communications device to the wireless terminal device, and transmit a voice stream transmitted by the IP base station to the wireless terminal device;
• and
• the first communication connection module and the second communication connection module work at a same time;
• wherein the first communication connection module comprises at least one of a Digital Enhanced Cordless Telecommunications (DECT) communications unit and a wireless fidelity (Wi-Fi) communications unit;
• and the second communication connection module comprises at least one of a universal serial bus (USB) connection unit and a Bluetooth communications unit;
• and
• wherein the processor is further configured to forward an incoming call to a specified account according to a preset call forwarding instruction;
• wherein the processor is specifically configured to forward all incoming calls to the specified account according to a preset Always Forward instruction, forward an incoming call received when a current account is busy to the specified account according to a preset Busy Forward instruction, and forward an incoming call not received within preset time to the specified account according to a preset No Answer Forward instruction.
