Abstract

The invention proposes a VoIP system, device and method based on cloud services. The system includes a VoIP terminal and a cloud network connected to the VoIP terminal; the VoIP terminal is responsible for initiating the session initiation protocol SIP negotiation, and determines the voice codec mode in the SIP negotiation; after the call is established, the voice signal without DSP processing Send to the cloud; after the cloud network processes the signal, send it to the remote VoIP terminal, and receive the voice signal sent by the remote VoIP terminal at the same time. By adopting the technical scheme of the invention, the problem of excessive load of the VoIP client in the prior art is solved, the cost of software and hardware of the VoIP terminal is reduced, and the use efficiency of the terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a VoIP system, device and method based on cloud services. Background technique [0002] The full name of VoIP is Voice over Internet Protocol, which digitizes the analog voice signal and transmits it in real time on the IP network in the form of data packets. Its basic principle is to compress the voice data encoding through the voice compression algorithm, and then decompress the data packets at the opposite end, and finally restore the original voice signal. [0003] The protocols adopted by VoIP mainly include H.323, SIP and other protocols. Among them, the SIP (Session Initiation Protocol, Session Initiation Protocol) protocol proposed by the IETF (Internet Engineering Task Force, Internet Engineering Task Force) has been widely used due to its good compatibility and scalability. SIP is an application layer signaling control protocol. A session used...
