What Makes SIP Special?

Session Initiation Protocol (SIP) is one of the hot topics in communications today. At first, that may seem strange. SIP is a signaling protocol—part of the underlying technology that gets communication from Point A to Point B on a network.  Specifically, SIP is used for establishing sessions in an IP network. The key terms here are “session” and “IP Network.”

In the past, communications protocols were designed either for voice communications or data communications. But a “session” isn’t just about one mode of communication. A session can be a simple, two-way telephone call or a collaborative multimedia conference. You can be on a voice session and turn it into a video session.  Or you can text someone and then turn that text session into a voice session. In effect, SIP makes the communications infrastructure transparent and seamless.  Just as you can click a link on a website and play a video, read text, listen to music or download a PDF, with SIP you can do the same with real time communications: voice, video, text, click-to-dial, etc.

Companies that want to take advantage of SIP will be acquiring SIP trunks from their local service provider. SIP trunks are a kind of industrial-strength communications line specifically designed to handle multimedia communications sessions. With a SIP trunk, you can bypass conventional public telephone lines and receive all your voice and data communications via Internet channels. Once set up, your incoming and outgoing calls are essentially free. The more calling you do, the more you save. In fact, Avaya customers typically see a return on investment of 6–12 months for their trunking solutions.

Another feature of SIP is that it is “geographically agnostic.” A phone number is no longer associated with a specific extension in a business. You can pick up calls destined for you at any location—just like you can pick up your e-mail at any location. This allows you to have a local number with a local presence, but have the calls handled in a centralized location. It also provides you with a built-in backup plan. If a location goes down, the calls can be handled somewhere else and callers will never know the difference.

All of this makes SIP one of the most talked about trends in communications today. Numerous market studies all agree that there is a huge surge in the growth of SIP trunks and the trend is almost certain to continue, particularly as initial concerns over quality and performance fall by the wayside.

The Agency Group, a global talent agency with offices in Toronto, London Los Angeles, New York and Malmo, Sweden uses SIP trunks to get all of its IP Office and Nortel communications systems working together. If the New York office suddenly experiences problems, calls can be rerouted through the other offices.
