The Ooma Linx wirelessly connects phones, fax machines or other telephony devices around the home to the Ooma Telo and Office using the latest DECT technology. It also gives users the convenience to install their main phone anywhere in the home if the Ooma Telo is installed in a remote area of the home. For Ooma Premier subscribers, the Ooma Linx provides access to a second phone line without using the Ooma Telo HD2 or HD3 Handset. Connect up to 4 Ooma Linx devices to each Ooma Telo or Ooma Office base station.
