Polycoms $129 Communicator speakerphone is a handy device for companies that want to regularly conduct multiperson conferences over Skype.
With its two built-in microphones, the Communicators reception was excellent when used for Skype calls in tests.
The voices of several people clustered within 5 feet of the device could be easily heard by the other parties on the line. Likewise, the speakers sound quality and volume were quite good.
Unfortunately, we could not reproduce the same fidelity when using the device for other VOIP (voice over IP) soft clients.
For example, we frequently experienced distortion and feedback when using the Communicator with X-Lite to make a SIP (Session Initiation Protocol)-based call.
