Polycom Communicator C100S USB Speaker Phone for Skype – Review

The Polycom Communicator C100S is a speaker phone that allows you connect to your PC/laptop (using the USB port) and make hands-free VOIP calls over the Internet via Skype (among others). This phone is optimized for Skype and you can expect to get good voice quality with it. It even has direct Skype launch buttons, volume up/down buttons and call pickup/terminate buttons. The Polycom Communicator C100S is a small/portable device that does not require any batteries (it can be powered through the USB cable).

Polycom is the leader in manufacturing enterprise audio/video conference systems and you can be sure that they have brought some of that technology to this device. The Polycom Communicator C100S is a full-duplex speaker phone that provides wide-band voice quality (22 Khz) that is enterprise grade. It also supports echo cancellation, which is crucial with VOIP systems as one can expect some echo when voice is transmitted over the Internet. There is a headset port which allows you to make private calls using a headset and it can even route your computer audio to external speakers, when connected.

Applications: Its specified seven feet voice pick up range is a good option for audio conferencing among small groups on either side. People can use this to make hands free VOIP calls (especially with Skype) over the Internet. Please note that you cannot directly plug in an analog phone line with this (unlike the triangle polycom soundstation2 phones) and you cannot plug this phone to the network port (it is not a stand alone device, it needs a PC to work).
