IP Internet Phone (VOIP) products
VOIP Background
VOIP (Voice Over IP) technology is the use of IP data network for voice transmission, a new high-tech achievements in the international community is constantly developing high-tech.The application of the technology development in the country by the Ministry of Information Industry, Science and Technology and other government departments, telecommunications industry and even of great concern all walks of life; long-distance IP phone in the country's popularity has been brought to the people and practicalwell-being.
Guangdong Heng Schindler Communications Technology Co., Ltd. developed HXD09 VOIP system is independent intellectual property rights with the domestic high-tech products, identified by the relevant authorities, has reached the international advanced level of similar products.
HXD09 VOIP system uses the most advanced of today's switching technology, in line with international standards for VOIP communications.Compared with similar products, with good voice quality, network delay effect is small, call privacy, and it can support multiple access methods can be used to replace the traditional PBX, etc.; the same time, the use of embedded network structure, andcompared to similar imported products, the installation process more convenient, do not change the original network configuration for a variety of network structure, expansion flexible, easy maintenance, low cost and other advantages, as domestic enterprises and institutions designed web application in the dataVOIP technology, the best choice.
HXD09 VOIP program:
A small investment to promote fast, simple application of the public voice value-added services, broadband network solutions, really suitable for large, medium, small chain, offices, SOHU family, etc. "hotline"
Branch of your business, or have a close partnership?
Enterprises can use the "HXD09", established between the remote offices within the free extension telephone network, and can also establish a hotline telephone cooperative units;

HXD09 VOIP network conditions to meet a variety of applications.Network topology is as follows:
HXD09 VOIP detailed analysis of the program
A. implement voice communication within the company
Note: any phone can call each other 1-4
Programme analysis:
1, the minimum equipment requirements: CPU, IPV, ASL, POWER, DTV, PC machines;
2, two or more HXD09 the same in an internal LAN switch, through the LAN for voice communication;
3, the voice quality is good, there is guaranteed bandwidth, 10M LAN IP voice maximum support 120 channels.
B. PSTN to achieve remote communication
Description: 1-4 can be any phone calls to each other, but one of the LAN into the INTERNET is a different application, and this time the two have a public address HXD09
Programme analysis:
1, the minimum equipment requirements: CPU, IPV, POWER, DTV (or AT0), PC machines;
2, you can make calls through the INTERNET and the transmission of data, cost savings;
3, the two sides HXD09 equivalent to PSTN / INTERNET gateway, PSTN access part can support SS7, ISDN, AT0, China One and so on.
C. to achieve WEB CALL CENTER agent or centralized management
Programme analysis:
1, the minimum equipment requirements: CPU, IPV, POWER, DTV (or AT0), PC machines;
2, the central office with agents, not agents of each branch, the call to the central office through the implementation INTERNET CALL CENTER function;
3, through H.323 gateway and Netmeeting calls.
Performance indicators:
1, encoding: Support G.723, G.729 speech coding, G.723 has 6.3kbit / s and 5.6kbit / s two.G.729 is 8kbit / s;
2, the bandwidth requirements: According to the voice coding is different from the 20.8kbit / s (6.3kbit / s, 30ms packet size + ip header) all the way to 28kbit / s (8kbit / s, 30ms packet size + ip header), 11.6kbit/ s (8kbit / s, 120ms packet length + ip header) range;
3, delay: to test the structure in the local area network transmission delay 50ms, depending on the specific application latency network performance decisions;
4, the maximum number of lines: as the network delay and bandwidth decided 10M LAN up to 120 channel voice;
5, support the protocol: H.323 protocol suite, SS7, China One, ISDN;
6, scalability: IP sessions to 6-way as a unit, according to requirements increase.
