Method and device for simultaneous communications of multiple lines of network telephone

Abstract

This invention discloses a simultaneous communication method of multiply wire network telephone, in addition to a device, used for structure network telephone with primary agreement SIP. The device comprises a network connecting port connecting a network; several telephone set connecting ports connecting several telephone sets; a voice code processing unit connecting to the telephone set connecting port, used for switching between the telephone voice and the digital voice; a network telephone distributing unit connecting to the network connecting port and several telephone connecting ports. It can set up the SIP control element including SIP calling couple, making the SIP control element connecting at least one telephone set port, and exchanging with the outer SIP number, building on-line to two-way transmit the digital voice pack.

Description

technical field [0001] The present invention relates to a method and device for simultaneous communication of multi-line network telephones, in particular to a network telephone device using the session initialization protocol SIP, which can enable multiple connected telephones to communicate at the same time, and only needs to have a single The network telephone communication method of the network telephone number. Background technique [0002] The development and progress of network technology has led to the continuous emergence of many new technologies, such as VoIP (Voice over Internet Protocol, hereinafter referred to as VoIP) technology, which refers to the voice communication on the IP network like making a phone call, which can save a lot of phone calls. The fee includes the use of telephone communication between two Internet-connected computers (PC to PC), the use of an Internet-connected computer through an integrated network switch (PBX) and general telephone comm...

Problems solved by technology

[0009] However, most of the current Internet phone gateways use VoIP H323 / H248 technology, and must use Internet phones, such as USB phones, and if the Internet phone gateway is connected to multiple phones, it must apply for a set of SIP for each phone. Internet telephone number can be used to communicate with more than one set of telephones, otherwise the line will be busy. Therefore, traditional Internet telephone gateways will use at least two sets of SIP numbers to connect to more than two sets of telephones without being busy. a waste of resource

[0010] In order to solve the above-mentioned inconvenience and shortcomings of the existing VoIP gateways, the inventor of this case proposes a VoIP device using the SIP architecture, which can connect multiple groups of telephones, and only needs to use the same group of VoIP numbers to simultaneously use More than one set of telephones for communication
