The Power of SIP
It would also be very easy for me to explain SIP (Session Initiation Protocol) by telling you about the INVITE message, Via headers, “302 Moved Temporarily” responses, and tag values, but that would most likely elicit the same “I’m sorry I asked” response. Instead, I will take my geek hat off, put my solutions cap on and tell you that SIP is a path to a world of integrated communications that will transform the way you do business inside and outside the walls of your company. Interested? Well, read on.
SIP was originally designed in the late 1990’s by two university professors, Henning Schulzrinne and Mark Handley. Their goal was that SIP would do for real-time communications what the protocol, HTTP, did for accessing information across the Internet. From the beginning, they looked upon all forms of communications as being equal. In other words, SIP doesn’t care if you are establishing a voice conversation, a video conversation, an instant message chat, or some form of communication that we haven’t even thought of.
Since the initial definition of SIP, it has been universally adopted as the way to implement Voice over IP (VoIP) and is fast becoming the adopted standard for video, presence, and instant messaging. However, that only scratches the surface of how SIP is transforming communication. For example, were you aware that with SIP you can route applications as easily as you can route voice? Did you know that one of the biggest adopters of SIP technology is the medical industry? Did you know that SIP can be used to light the message waiting lamp on your telephone, tell your colleagues that you are out of the office on vacation, and send the photograph of a car accident to a 911 emergency responder?
Over the next several weeks and months I intend to explore the many different facets of SIP while presenting real-life scenarios of where SIP is changing the way we do business. Yes, I will probably throw in words like INVITE, SUBSCRIBE, and just might even talk about that “302 Moved Temporarily” response, but it’s my goal that I reference the technical mumbo-jumbo in ways that make sense and help you envision new solutions that will be beneficial to you and your business. So, please check back every now and then and I promise to provide worthwhile information that will help you do a better job serving your customers and employees. Better yet, if I’m lucky I just might turn you into an evangelist as zealous as I am about the power of SIP.
