VoIP gateway solution

VoIP, that is Voice over IP (voice service realized by sending IP packets), it is a packetization and digital transmission technology based on IP technology, and its basic principle is: the voice compression algorithm is used to compress and encode the speech, and then These voice data are packaged according to IP and other related protocols, and the data packets are transmitted to the destination through the IP network or the Internet, and then these voice data packets are serialized, and after decoding and decompression processing, they are restored to the original voice signal, so as to achieve The purpose of the IP network to transmit voice. Can provide predictable, real-time, long-distance call quality voice and fax communication services. VoIP is the ideal choice for companies scattered around the country who want to save money on long-distance intra-company communications.

[System Principle]

Passing voice and video signals through the IP network will be one of the trends in the future development of IP network applications. VoIP technology can realize the transmission of voice through the IP network while interconnecting the remote networks, which can save a lot of long-distance calls and even realize zero-cost IP phones within the company. The application gateway system is an important part of the VoIP system, which not only completes the implementation of the main business layer, but also a powerful switching platform. Through the application gateway, the various systems of the enterprise are organically connected together. In addition, through the application gateway,

Enterprises can also easily connect to external networks or specific hosts. The application gateway can be connected to a variety of powerful back-end support systems, which can facilitate enterprises to continuously develop new service varieties, which can not only facilitate customers and establish corporate image, but also Bringing new business growth points for enterprises.
