Why hasn't VoIP made more of a dent in traditional telephony?
During my first few weeks working at OnSIP, I spent a significant portion of my time learning about VoIP, and more specifically, about SIP, the de facto signaling protocol most widely used for setting up voice communication sessions over the Internet. I tried out other SIP applications such as video, presence, and IM, and found it convenient that I could access all of these applications using a single point of contact, my SIP address. With SIP, I discovered that both the media type and what a person uses as his access point don’t matter (SIP phones or anything that can run SIP software will allow the user to get access to his applications).
It clicked with me. I could make a high definition call, conduct a video chat, send an IM, etc. using an address that looks like my email address. Best of all, I could do all of this for free using the Internet I already pay for.
I distinctly remember thinking to myself that it was only a matter of time before the excitement around this technology started having serious impacts on traditional telephony.
That was almost 4 years ago, and as far as I can tell, my prediction has yet to happen. What happened?
