We've Rounded Up 42 Of The Hottest Next-Generation Switching Platforms

The original title of this roundup was "Voice/Data Switches & IP-PBXs." But as we began to collect information on the plethora of equipment that may be classified under that heading, we realized that using only two phrases to describe these products would be limiting to their manufacturers, and to the industry as a whole. The next-gen network is a valuable investment for service providers and carriers, and the many components that enable analog voice to be packetized for even part of its transport journey are crucial elements in building this infrastructure.

When putting together this lengthy roundup, we looked at standard Internet telephony gateways, softswitches, edge access devices, and even the peripherals that allow these devices to perform their switching tasks. The majority of the products can certainly be classified as voice/data switches and IP-PBXs, but whether they sit at the customer premise, in the central office, or somewhere on the edge of the public network cloud, they all perform data conversion and transport functions that are critical to the success of the next-gen network.
