Softswitch Technology Key Terms

Consider softswitch technology key terms as you look to upgrade your network

By Kristan Hart

Softswitch technology refers to a programmable network switch that can process the signaling for all types of packet protocols. Also known as a "media gateway controller," "call agent" or "call server," such devices are used by carriers that support converged communications services. This programmable network switch is a software-based solution that is implemented on computers and servers. Softswitch technology offers business owners new services and revenue stream options, and it's very flexible in its deployment and in its operation. Unified messaging means easy integration into your network. Plus, softswitch technology costs less than a traditional circuit switch. Consider these key terms as you study softswitch technology.

Softswitch

Softswitch is a software based voice and multimedia switch. It replaces the old switches based on circuit switching technology. Other terms used with softswitch are "Call Agent" or "Media Gateway Controller" because they are key components in VOIP technology. However, the term softswitch is used with both VOIP and networking.
Try: Read over the definition of softswitch on the ZDNet website. The website details the capabilities of softswitch technology and the features that make it so flexible, and a great feature for business owners.

VOIP softswitch

A VOIP softswitch's main responsibility is to route calls across different networks. There are however, many responsibilities for VOIP softswitches.

Session Initiation Protocol (SIP)

Session Initiation Protocol (SIP) incorporated into softswitch technology allows IP telephony service providers to offer the ultimate package of communication services at low costs.
Try: PortaOne uses Session Initiation Protocol to help provide the full spectrum of call routing features and to maximize performance in voice networks both large and small. The Session Initiation Protocol (SIP) page on the Columbia University website defines the role of SIP in softswitch technology.

Class 4, Class 5

As the "generations" of softswitch technology get older, the class number becomes larger. Class 5 softswitch is more advanced than Class 4.
Try: View the features of Class 4 softswitch and Class 5 softswitch on the Topex website.

Internet telephony, VOIP, VOI

Internet telephony contact is made via the Internet. Internet telephony includes voice, fax and video phone calls. It's also referred to as voice over internet protocol (VOIP) and voice over Internet (VOI).

Conference bridge

Conference bridge is a new feature to softswitch technology, allowing you to conduct conference calls using your softswitch. A conference bridge of a VOIP softswitch has the same options you would find through a traditional conference bridge service.
