What Is a Broadband Phone?

Broadband phone is a voice communication software based on VoIP technology. It forms a complete voice communication platform with voice exchange server, telephone gateway and contact exchange server. It also supports hardware including USB voice communication handle, USB-RJ11 conversion box, and PCI-RJ11 conversion card. The product can provide communication services of PCTOPC, PCTOPhone, and PhoneTOPhone on a network based on the TCP / IP protocol, which can meet the needs of telecommunications operators and broadband operators to provide communication services and enterprises to solve communication problems.

Broadband phones are also known as Internet phones or broadband Internet phones. Refers to users using IP voice terminals connected to a broadband network. Point-to-point IP voice services completed through multiple networks and devices over lP networks such as the Internet. Broadband telephony is based on lP technology, with a broadband transmission network and IP terminals as carriers. It is a new type of telecommunication service that combines voice and data communications. Because the number of switching equipment required is less than that of traditional telephones, its operating costs have been greatly reduced, resulting in a natural tariff advantage. A concept closely related to broadband telephony is lP telephony. From a technical point of view, a broadband phone is an lP phone, but since there is already a relatively clear regulation on the business scope of lp phones in China, we cannot equate it with lp phones when discussing broadband phones ^[1]
