Abstract

The present invention relates to a P2P-based IP PBX. The key of the present invention lies in that the call quality is improved by applying the P2P technology, a plurality of concurrent VoIP calls can be supported at a single node, and can be seamlessly docked with the existing telephone.

Description

technical field [0001] The present invention relates to peer-to-peer network technology (P2P: Peer to Peer) and computer telephony integrated technology (CTI: Computer and Telephony Integration), relate in particular to a kind of IP (Internet Protocol) user exchange (PBX: Private Branch eXchange) based on P2P technology . Background technique [0002] VoIP (Voice over Internet Protocol) refers to the transmission of voice signals in the form of data packets in an IP network environment after compressing and packetizing analog voice signals. The basic principle of VoIP is: compress the voice data encoding through the voice compression algorithm, then package the voice data according to the IP standard, send the data packets to the receiving place through the IP network, and then reassemble the voice data packets. After decompression processing, it is restored to the original voice signal, so as to achieve the purpose of transmitting voice through the Internet. [0003] Give...
