VOIP network service industry entered the high-speed developing period in 2005, the U.S. will be decided to be VOIP in 2005, promote in entire United States, also widelyd popularize the VOIP networking telephone in Europe as countries such as Germany in 2005, the communication technology of the VOIP networking telephone is ripe gradually at present, has the provinces and cities of considerable part to open this service at home.

Traditional IP phone service is that IP phone service provider is responsible for voice are looked for and is put into Internet behind the bag and goes up transmission, the user must pay (0.11 yuan/minute of packing local telephone expenses before, for example dial 17909 telephone expenses that produce) and Internet on packing and transmission cost (0.3 yuan/minute, both the long-distance telephone expenses of IP).Though the Traditional IP telephone service has reduced telephone charges usefulness, for the enterprise of a heavy traffic, the IP phone expense still is a spending of not wanting.

Network is a kind of means of transmission data of cheapness, if can utilize network to make a phone call, that will greatly reduce the expense of enterprise undoubtedly.In the prior art, can realize PC to PC.

PC to PC just between the two computers, carries out voice transfer by network, this mode is very common, and nineteen ninety-five VocalTec has released first based on the PC of the data network IP phone software product to PC.In March, 1996, VocalTec announced Dialogic company's first telephony gateway of co-production (Gateway) IP network and conventional telecommunication network to be connected by telephony gateway, make IP phone more general, more cheap, have a stronger mobility.From at the beginning of 1996 to the end of the year 1998, the telecommunication department from the production firm to various countries all has been put into the emphasis of work in the work such as formulation of production, networking and communication protocol of relevant IP phone.

At home, the VOIP service beginning of China in 2003 replaces traditional PSTN gradually aspect toll telephone; Estimate that according to iResearch with dominate, especially PSTN will be replaced by VOIP VOIP service in 2008 fully aspect international long-distance in China Telecom toll telephone market.The main business operation model of China has two kinds, and the one, the virtual VoIP of the Internet that places one's entire reliance upon, the main business form is the voice-enabled chat function of voice-enabled chat chamber and instant messaging; The 2nd, based on traditional VOIP of telecommunications network, the main business form is the IP telephone service that telecom operators provide.The influence of national security and political economy is the problem that the government emphasis is considered, so the supervision of the telecommunications of government just is not only the behavior of standard telecommunication market, more is conceived to the stable and rapid development of whole country.

Now a lot of companies client for convenience seek advice from, order, and have opened 800 freephones, but 800 freephones are that this will be a very huge spending undoubtedly for the company of a heavy traffic by all telephone expenses of the payment user of company.When if the user browses the homepage of a company on network, can directly dial in the intercommunication phone of the said firm by the computer of user's use, all be a kind of " zero telephone expenses " so for both sides, to thoroughly change the communication modes of existing society undoubtedly, greatly save telephone expenses.
