IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the costs of the traditional telephone networks.

VoIP (Voice over IP) is an organised effort to standardize IP telephony. IP telephony is an important part of the convergence of computers, telephones, and television into a single integrated information environment. Also see another general term, computer-telephony integration (CTI), which describes technologies for using computers to manage telephone calls.

The use of IP lines or SIP lines (Session Internet Protocol) to replace old analogue, ISDN2 and ISDN 30 lines is rapidly gaining pace and accounts for approximately 50% of all new telecom lines and handsets sales. NB Data has a wide range of IP solutions including office SIP handsets, USB headsets/USB headset connectors that are ideal for home workers, VoIP/PSTN switches to convert existing headsets/handsets, IP Call Recording, CTI integration for screen popping customer records from your database and much more.
