Revolabs FLX 2 is the world's first wireless POTS/PSTN and Bluetooth-capable conference phone for small to medium conference rooms and executive offices. The unique modular design provides maximum flexibility for speaker and microphone placement with a handset for dialing and private conversations. Video conferencing units and personal computers can be connected using audio in/out ports. The phone will bridge calls from a POTS/pstn or a smartphone connected with Bluetooth to calls from a video conferencing unit or a computer-based UC client such as Skype for Business, Zoom, Vidyo and Hangouts. The 10-FLX2-020-POTS model comes with 2 directional tabletop wireless microphones to pick up the speech of one to three people directly in front of the microphone, integrated noise cancellation prevents other unwanted room noise from becoming part of the experience, and impervious to GSM noise from other wireless electronic devices, secure: 128-bit encryption means no one will be able to listen in on the signal sent between the microphone and base station, and 8 hours of talk time.
