Session Initiated Protocol (SIP) is talked about a lot these days. In a generic definition, SIP is a flexible protocol for connecting two or more devices over an IP network. It has great breadth and depth with multiple major functions, from user location & registration, user availability, user capabilities, session set up to session management and more. * In the real world, it has become an extremely cost-effective approach for connecting telecommunication devices (ie. phone systems) to one another. When combined with the proper SIP gateway server, this technology allows you to harness the power of the internet to connect with the traditional public switched telephone network (PSTN).
As Network World stated, “One of the wonderful things about SIP is that it is a text-based protocol modeled on the request/response model used in HTTP. This makes it easy to debug because the messages are easy to construct (if you’re a developer) and easy to see (if you’re a network manager). Contrasted with H.323, SIP is an exceedingly simple protocol. Nevertheless, it has enough powerful features to model the behavior of a very complex traditional telephone PBX.”
So why does this matter? Simply put, this can save you money by lowering your telecommunication bills and can be used to set up real-time multimedia sessions, which are both necessities in today’s business world. Further, it gives you the ability to transport a call directed at one area code to a different area code without a call forward. We believe that SIP is a proven and effective technology when properly deployed. If you would like to learn more, please speak with our experienced team of voice professionals.
