What Is Available

What Is Available
More than 40 video call software solutions are on the market today. Many are not very
good per our rating system, but solutions are continually improving. In the three years since
I started using video calls with my 4–year-old daughter, family, and friends, the amount of
video call solutions available has doubled if not tripled.
There are basically two types of solutions: free and commercial (pay-per-use). Within
these two options are SIP, H.323, and custom or proprietary solutions. Commercial solu-
tions tend to have more features and offer multiparty connections. Free solutions tend to be
basic and may offer additional services as pay-per-use options. Oddly enough, when we
rated the video call solutions over the past two years, we found only a few solutions ?oated
to the top of the list and it had little to do with cost. Some of the commercial solutions are
surprisingly costly for what they offer and the quality they provide, but the quality will
improve with time. So the manufacturers of these solutions are really going after their busi-
ness model and unique way that they want to provide you a video call solution. Most com-
mercial solutions are geared for business use and not personal videoconferencing, though
there is some overlap. It all depends on what your personal needs are.
We have a short list of video call solutions to recommend, but there are different solu-
tions for different situations.The focus of this book is personal videoconferencing, so the
short list rates computer-based solutions for one-on-one video calls for Windows-to-
Windows or Windows-to-MAC (Apple). We will discuss more on bridging the gap
between computer video call software and hardware video telephones in Chapters 6 and 7.

SIP and H.323
There are other video call solutions that I like but are not on the short list because of
one feature or because they are still in the development or testing phase. For example, a
plug-in for Skype called Video4IM is a good solution for Skype, because the video sender's
screen is larger than Skype's video screen, but it is still in testing. WigiWigi, which is still in
testing, holds great promise in high-quality multiuser video calls and works with any instant
messaging application (the IM applications do not have to be the same).There are many
solutions in the market, and we will list them all in Chapters 6 and 7.
