For those who don't have video capabilities yet, what can they do to better position themselves?
They should start simply and not overpromise the amount or quality of video they can deliver. What are the greatest challenges in deploying voice over IP?
Proving short-term ROI is the biggest challenge. Our voice systems today are feature-rich and of high quality. Who are the vendors to watch in this space?
That is a subject that can take hours to discuss. Enterprises should start with their incumbent service and network vendors, and should not assume that it is necessary or desirable to tear out all their current systems, nor to force a migration to a single vendor for voice, video, wireless, etc.
FOR MORE INFORMATION:
Both technology areas have a long growth ahead of them, but clearly voice is the most pervasive and portable form of communication that humans use, and it can be delivered with less complexity than video. I don't see a race or battle between voice and video; I see them as complementary communications. Do most organizations have a network that is prepared to handle video over IP?
No. Most organizations will need to upgrade to support multicast and caching. Remote locations may require more raw bandwidth, especially if real-time video will compete with other services on a WAN [wide area network] connection. How will this technology evolve over time?
The "phone" of the future will be a software application. The premise equipment market as we know it will disappear. Can you give an example of an organization that is effectively deploying voice over IP right now?
Without mentioning specific names, I would consider companies with remote call centers as some of the most successful with leading edge, portable voice over IP systems.
