At present, most enterprises in China have already connected to the data network and started to carry out various services, such as office systems, on the network, how to enable your data network to bring more benefits to enterprises is already a very realistic problem for enterprises. On the one hand, we consider using the data network to improve production efficiency, on the one hand, it is highly cost-effective to consider cost savings through data networks, especially for those enterprises with many branches and scattered regions that use the public PSTN to provide communication between Headquarters and branches.
It is a heavy burden for small and medium-sized enterprises with limited funds. Using the original data network to run the voice service can save a lot of communication costs and improve work efficiency. This article will introduce some suggestions for the transformation of the original network and the VOIP service.
Transformation Scheme
1. Add a VOIP gateway to the original network
You can add a VOIP gateway to the headquarters and branches. The topology is as follows:
VoIP gateways are mainly used for IP telephone communication between enterprise branches. They can provide traditional voice interfaces and connect to existing enterprise telephone switches (PBX) or group telephones, and bypass the long-distance phone to the IP network Internet/Intranet ). The main feature of VoIP Gateway applications is to make full use of existing network resources, save users' long-distance calls, and combine with the existing traditional telephone switch (PBX) or group phone of the enterprise, traditional speech can be gradually transferred to the IP network without affecting the existing voice network of the enterprise.
2. Add VOIP gateways to the headquarters and add broadband IP addresses to the branches
This design is suitable for branch offices, but it costs a lot to communicate with other branches. You only need to assume a VOIP gateway at the company headquarters, you can add a broadband IP address in the branch, for example:

1. Voip Gateway
Some small-scale VoIP gateway products are available to small and medium-sized enterprises (SMEs). These products generally provide four or eight telephone relay interfaces and simple routing functions and network interfaces, the telephone switch or group phone of an enterprise branch can be easily connected through an IP network.
For small and medium-sized enterprise users, VOIP gateways of major manufacturers such as CISCO and 3com are expensive and difficult to accept. The functional performance of VOIP gateways of some domestic manufacturers can also meet the needs of General small and medium-sized enterprises. The following describes two products.
Beijing gongye GS Voice Gateway
The speech GS gateway developed by Beijing gongye Technology Co., Ltd. has its own intellectual property rights. It integrates gateway and voice exchange, and supports lines 4, 8, and 32, it is interconnected with mainstream vendors such as CISCO and 3com, and supports multiple H.323 variant protocols. In addition, the WEB-based management interface is intuitive and easy to operate.
CNG300/CNG800IP Voice Gateway
In addition to the conventional IP voice gateway function, century Netcom also provides IP address teleconference and IP Call Center), virtual IP office, division of labor, and other functions. The product image is as follows:
2. Broadband IP telephone
YWH100 series phones of Henan yueneng
YWH100 series network phones are made up of DSP Chips and are widely used for voice communication in a broadband IP network environment that complies with the TCP/IP protocol. This product can be divided into single port and dual port, A dual-port phone can no longer use a single switch port for the phone.

Comments:
By Adding VOIP devices on the basis of the original data network, SME users can reduce communication costs: the enterprise can achieve "0" calls internally; the enterprise can communicate with the local telephone network where the branches are located, saving long calls, only local branches are responsible for the use of municipal phone bills; "scale-down dialing" can be achieved, the dialing rules are simple, the dialing time is shortened, and the work efficiency is improved.
At the same time, we should also have some knowledge about problems that may occur in the application of VOIP. If a power failure occurs in the branch, communication will be affected, and VOIP phone users call 119 or so, the phone may not be automatically transferred to the nearest fire alarm center. Broadband IP Phones require separate power supplies and are also affected by power outages.
However, VOIP users not only need to obtain traditional voice and fax services at a lower cost. Users will also benefit from some breakthrough new services based on VoIP. VoIP completely changes the communication mode. New applications, such as web-based call centers, collaborative whiteboards, and remote communication and exchange, are potential VoIP services in the future.
We have reason to believe that VOIP will bring greater returns to small and medium-sized enterprise users.
