Polycom OBi302-UK Universal Voice Adapter

The Polycom OBi302 expands your service portfolio by enhancing the communication possibilities of home offices with flexibility in voice, fax and modem applications as they transition to the digital communications world. Home and business offices can maximize 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 prioritises phone calls above other internet traffic 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 office users can send and/or receive reliable facsimile calls over the Internet.
