Enterprise VoIP: VoIP's core values and programs of choice-VoIP

, on the 1st pass, call center - the communications industry

The term for VoIP Public Is no longer fresh, the concept from the introduction of VoIP, and now has been for many years.

In these years, VoIP has been from the beginning Advertisement Sought after star, gradually indifferent to the technical term for an alarm. It is in this change appear to be normal, but almost just like an undercurrent in the quietly surging.

VoIP hair force since 2005, bid farewell to the former maverick gimmick mode and began to march practical enterprise network market, so many companies have already begun to deploy VoIP within the enterprise Communication As an infrastructure to do.

Early VoIP, voice quality tests, the transmission time will be extended, on and off, voice distortion, and its related key devices and gateway technologies are not mature. The development so far, its technology has already far exceeded the past, with several orders of magnitude performance increase on. In addition, as new technology continues to advance the stability of data networks is gradually moving closer to the traditional communication systems, VoIP network stability has reached a new level. Word, VoIP technology has matured.

Sector as a giant of a Cisco network company, has been leading the trend of new technology. Currently Cisco All Chinese companies Desk Both the deployment of Cisco's own production of IP Telephone . Cisco's internal telephone, regardless of playing in Europe, America, or Africa, the use of VoIP technology to run on the Internet, it is free, it greatly reduces the communication costs across regions; and Cisco's Chinese employees in the world any place where the Internet, will not miss a hit their office on the telephone, to ensure real-time virtual office online.

VoIP is not just to save money

Although the use of VoIP, the company's communication costs have a significant decline in general but for some companies, said that there might be insufficient bandwidth, dedicated, and if the bandwidth requirements for VoIP solution to upgrade network increase the bandwidth, then the sum of the expenditure of funds, will allow greatly reduced the cost advantage of VoIP.

Cost advantage is not obvious why we insist on the deployment of VoIP? This is because, VoIP on behalf of the Table Is a kind of work, a means of communication, modern business communications should be based on IP network communications, Package Including voice, video, instant messaging, fax, call centers, CRM (customer relationship management) systems commonly used means of communication of any enterprise. In this sense, considering the deployment of VoIP can not only simply consider the reduction of call charges. There are many costs can not be used to compare the exact numbers, such as using IP-based voice and data networks, to improve the efficiency of office communications; well as easy to use, bringing the growth in call volume and thus the to work efficiency, direct telephone communication than Electronic E-mail is much more direct and efficient, but the potential value of the business can play.

VoIP's biggest benefit is that IP technology to meet Mobile And convenience needs. The convenience of the mobile is through IP networks, can be achieved PC And PC, PC and phone, telephone and telephone docking. Many companies are willing to adopt new technology to improve production efficiency and cost savings. Global business and economic globalization, need for integration into a global communications architecture, VoIP architecture is global, in a place where the Internet, you can and partners for voice and data communications. This is a low-cost VoIP Aside from the communication, the most remarkable is the rapid development of its inherent power.

Needs of enterprises deploying VoIP For enterprise VoIP network

, to secure voice Service Stable and reliable operation is critical. To ensure call quality in an acceptable range, the VoIP network must implement the necessary quality of service in order to control the VoIP packets in the transmission of packet loss, delay and jitter. As the voice for the normal operation of enterprises is critical, therefore the implementation of VoIP technology for network management are also made after the very high demands. Network management system not only needs to be done for real-time device monitoring, fault diagnosis and recovery, may also need to record the time of each call, length, calling / called party information. In addition, because business users are accustomed PS TN network reliability, and therefore the reliability of enterprise VoIP very high demands.

For enterprise users, the network can support the requirements of applications and features determine the requirements for VoIP networks. First of all, should be platform independent. VoIP network should be associated with a manufacturer's equipment and management platform-independent, should be able to accommodate devices from different vendors. This requires, vendor solutions must be considered based on open industry standards is a good solution.

Enterprise VoIP technology program options Enterprise VoIP technology program currently has three choices:

The first is a program H.323 VoIP is the most mature program, with mature technology, equipment type is rich and good interoperability. The current version of H.323 has been developed to V4. Function in the Agreement, H.323 support for voice and supplementary services, video services, data services, providing bandwidth control, mobility, centralized call control mechanisms; from the device manufacturers support the status quo of the agreement, see, H.323 supplementary services in voice and and video business is very mature, communication quality can be achieved using the requirements of good compatibility between devices; in the provision of voice and video aspects, H.323 is the most mature industry, application of technical solutions most widely.

Second technical solution is MGCP/H.248 program, that is, "softswitch." MGCP, and H.248 is a soft switch system in the main field in the packet network the call control protocol. Softswitch is a next generation IP in order to Telecommunications Network simulation and emulation of all PSTN and smart on-line voice and supplementary services. Mainly used in the current soft switching system operators in the field, very few applications in the enterprise market, there is no technical advantage. For operators to deploy softswitch is the development trend of the follow-up voice, can provide a variety of rich and unique nature of business, such as unified messaging, Number portability, the 1st pass, PCto Phone, Internet Call Waiting, Voice Portal and so on.

SIP is the IETF developed call control co-organized
