Description

technical field

[0001] The invention relates to an application of VoIP technology in the field of converged communication, in particular to a VoIP voice service running on an intelligent terminal. Background technique

[0002] For a long time, people have been paying attention to how to carry out long-distance voice communication. In the past 100 years, we have all relied on the public telephone network PSTN (Public switched Telephone Network) for voice communication. When two places talk, there is a fixed line allocated to both sides of the conversation. Although there may be redundant bandwidth in this line, other information cannot be transmitted at the same time. When data communication services appear, this communication method based on circuit switching gradually exposes its defects of low resource utilization efficiency and reliability.

[0003] Not only that, the emergence of voice and data integrated services has also put forward higher requirements for traditiona...
