32-port VOIP

 Voice Gateway is the IP-based voice / fax / data services, integrated access devices (IAD) and Access Gateway (AG), located at the access layer in soft switching system, the main function is to unify the various network terminal access, so that the various services in packet-switched networks unity can be achieved. In the existing circuit-switched PSTN inheritance and business based on the characteristics, IAD combines all the benefits of IP technology, enabling a smooth transition to NGN traditional PSTN network; at the same time, making full use of existing PSTN equipment on the basis, IAD We can provide a broader range of value-added services, to provide customers with the best balance between business development and network construction and upgrades. Voice gateway provides 4 to 32 VOIP channel, mainly used in government, industry, large enterprises (Group), Communication Network, is public security, political and legal, tax, finance, electricity, water conservancy, transportation, education and other government sectors units grassroots voice over IP ideal device access.


 Carrier-class reliability
