Hi,
I am a affiliate member of the Madison Dynamics website. Here is my affiliate link.
http://www.madisondynamics.com/index.php?59750
As an affiliate I can earn by promoting the products sold by Madison
Dynamics. One of the product sold is their flagship product the Icon
Communicator.
iCONCommunicator operates through Voice-over Internet Protocol (VoIP).
The many features and uses of the product can be found by visiting the
following webpage.

I am planning to promote and sell this Icon product to corporates. But
prior to this I would like to
1) Get some basic knowledge of VoIP technology. How does this compare
with other technologies used for Internet telephony.
2) Read some product reviews of the Icon product by reputable
technology related websites/magazines.
3) Get to know which are the products which would compete with the
iCON product in terms of comparable features and price and quality. I
would like to read product reviews of these competing products as
well.
