Boardroom table and Conference IP Phones are sufficiently different than regular desk top telephone devices. They are specifically designed for larger rooms with a wider field of audio microphone capture.
Conference room table phones can have a single main device console (used for dialing, accepting / receiving calls). To broaden the field of audio capture in the room - expansion microphone modules are generally used - especially in larger corporate meeting room environments.
New technologies on the market ring in the digital video calling age with additional camera and SIP Video calling expansion modules, as well as integrate with PBX Phone systems for business.
Some of the conference room ip / boardroom phone devices we carry also offer Android app store and other third party app integration to extend further functionality and features.
