• Does not connect to any other devices
• Is focused solely on Skype (integrated
Skype button)
• Questionable performance even with other
PC applications. According to Polycom FAQ
on the Communicator: "Skype is the only
application that is officially supported by
Polycom Communicator model C100S. It is
optimized for use with Skype, and if used
with other Internet calling or voice
applications, Polycom Communicator may
experience diminished audio quality and/or
loss of button functionality."
No on-board DSP processing -
code is loaded onto hard drive of connected PC:
• Audio processing tasks compete for CPU
resources with other PC applications such as
video conferencing over internet
• This could affect echo cancellation and duplex
performance
• No ability to ever connect to non-PC devices
because it contains no built-in processing
