With the development and popularization of Internet technology, VOIP technology has matured to the traditional voice quality results.
Based on data communications network, using compression technology, reducing international and domestic long-distance telephone charges, to achieve point-free calls, unlimited communication. Perhaps the concept of VOIP is very clear we do not, in fact, VOIP (VoiceOver Internet Protocol) is an IP-phone-based, value-added services and providing corresponding technical, that is, the original analog voice signal to the "data packets "The type in the IP data network to do real-time delivery.
VOIP gateway VOIP adapter is the key to achieve. Gateway adapter is designed to complete conversion products for the voice signal from the packet (or IP) into the form PS TN using the form or the opposite conversion. In the IP Communication In the definition of the gateway adapter is a link between traditional Telecommunications Road and bridge data. In short, the gateway adapter digital phone signal, then the compression, coupled with the packet, and then through the InternetProtocol (IP) sent a different path. On the contrary, the receiver's gateway adapters to be collected in all packages and decompression, and then to simulate the form sent to the telephone. Since VOIP is the transmission through the Internet, VOIP need to run a smooth network environment. As the Internet network to transmit voice, low cost, for the frequent use of long-distance telephone companies, not by time or number of charges, only a fixed monthly Internet use fees for enterprises to reduce the high fixed cost of IDD calls. VOIP gateway adapter and a regular telephone connected, will not affect the existing telephone system.
Today, we IT 168 evaluation center will be beneficial for everyone to bring several Lobos transport technology product introduction and SkyMe Test The products can be achieved through Skype software functions related to VOIP.
In the test, we then we will first explain briefly the working principle of VOIP and advantage.
VOIP working principle and advantages Description:
The whole process of calling via the Internet, that is to make the sound into an analog signal through the telephone, the analog signal into a computer terminal through VOIP data packets, data packets on the Internet and upload them onto another computer terminal VOIP, VOIP computer terminal data packet is converted to analog signals, convert the analog signal through the telephone voice. If the fax via the Internet the entire process, which is making the text files and images through Fax machine Analog signal into an analog signal is converted to a computer through the VOIP terminal data packet, data packet on the Internet and upload them onto another computer terminal VOIP, VOIP terminal computer data packets into analog signal, analog signal is converted to text via fax and pictures.
VOIP terminal achieved data transfer on the premise that the computer needs of the computer terminal must be connected to the Internet, and on both sides of the terminal computer must be equipped with features of VOIP gateways to achieve a call, call switching, transceiver fax functions. If the user's terminal computer, installed only the voice communication software such as Skype, you can only by computer Microphone With Headset Simple voice chat calls, but can not be achieved telephone answering, call forwarding, fax and other functions. Phone connected to the network bandwidth of the network also have certain requirements, generally one-way Internet phone to take up about 15K of bandwidth, while the bandwidth requirement is relatively stable. If the four-way Internet phone calls simultaneously, will have to take up bandwidth to 60K or so. To ensure call quality and convenience to Telecom ADSL Business, for example, the user is using a monthly subscription 512/2M of ADSL lines, basically a network to support more than 8 phone calls simultaneously. Of course, the user can choose other forms of broadband monthly landing approach, as long as the bandwidth to ensure sufficient and stable, can meet user requirements of normal conversation.
For the average individual users, more convenient shopping features VOIP Adapter with Skype voice communication software to meet the requirements, and for business users, you need to purchase business VoIP Internet Switch The dynamic allocation of IP addresses to achieve in the case of finding one another on the Internet VOIP terminal computer, the Internet telephone company network switches in addition to helping to find another VOIP VOIP terminal devices, also provides value-added services such as flight line, password control and other management functions .
If Hong Kong and Guangzhou terminal computers are also equipped with VOIP adapter, you can only achieve through the Internet for free calls, and through traditional Fixed telephone Takes calls 0.97 per minute to 3 of Hong Kong dollars; beat Hong Kong by the Guangzhou VOIP broadcast local fixed telephone, you need to Guangzhou, the local VOIP fly line to the desired computer and then play the numbers on the broadcast, it simply is through the local Guangzhou The VOIP adapter use of fixed-line local broadcast Guangzhou Hong Kong needs to play connect the Guangzhou numbers, in order to achieve localization of long-distance calls cost only a Guangzhou local fixed line telephone bill for the required 0.11 yuan per minute, and through traditional fixed Phone calls will cost 0.97 per minute required to HK 3; VOIP broadcast by Hong Kong fight domestic long distance calls, the principle of playing with Guangzhou local ordinary telephone broadcast exactly the same, it simply is through the use of Guangzhou, Guangzhou, the local VOIP adapter Local The fixed line connected to Hong Kong needs to fight broadcast domestic long-distance number, the cost is only broadcast in Guangzhou local fixed domestic long distance telephone bill for the required 0.41 yuan per minute, while calls via traditional fixed-line telephone will need to spend 0.97 per minute 3 Hong Kong dollars; By contrast over the Guangzhou local broadcast play by VOIP phones in Hong Kong is the same principle, that is, the local VOIP adapter via Hong Kong using Hong Kong's fixed line local broadcast play connected to Guangzhou, Hong Kong telephone costs, the traditional two fixed-line needs to be charged 2.4 yuan per minute costs, and by IP Phone Cards Need to 1.5 yuan / minute costs, by the way VOIP Internet phone can make free calls, mainly due to local city monthly in the form of words is any play.
