2 line VoIP Adapter connects home and business analog
phones to the digital voice communications world
Polycom OBi302 expands your service portfolio by enhancing the communication
possibilities of home oces with flexibility in voice, fax and modem applications as they

their current analog investment by keeping up to two analog phones or fax machines
subscribed to up to four independently configurable VoIP services, one OBiTALK peerto-peer voice service, and one POTS (Plain Old Telephone Service) subscription*. This
dedicated device prioritizes phone calls above other internet trac coming through the
LAN port to ensure users clearly hear every important word. Alternatively, with support
of the T.38 fax standard, home and business oce users can send and/or receive
reliable facsimile calls over the Internet.

placed anywhere within range of a 2.4 GHz or 5 GHz, 802.11ac wireless access point
when used with the Polycom USB WiFi adapter. Similarly, the USB Bluetooth adapter
pairs a user’s mobile phone or Bluetooth audio headset so they can place and answer
calls using their mobile service via analog phones.
