IP PHONE SYSTEM
A IP phone or VoIP phone uses Voice over IP technologies for transmitting telephone calls over an IP network, such as LAN and the Internet, instead of the traditional public switched telephone network (PSTN). VoIP has a leg-up on PSTN in many areas, such as scalability, cost and special feature availability.There are some features that are available on traditional PSTN for an extra cost. These include music on hold, conferencing, call log and call recording. These are available on the new VOIP for no charge. Remote extensions are a standard feature with VOIP. Such extensions for branch offices and teleworkers (PABX extensions) are expensive with PSTN and for every remote extension additional dedicated lines are needed.
