A VoIP telephone, also known as a SIP phone or a Softphone, uses Voice Over IP (VoIP) to place and transmit telephone calls over an IP network, such as the internet. VoIP converts the standard telephone audio into a digital format which can be transmitted over the internet and also converts incoming digital phone signals coming from the internet to standard telephone audio.
A VoIP telephone allows users to make phone calls using VoIP, to any softphone, mobile or land line. A VoIP telephone can be a simple software-based softphone or a hardware device that looks like a common telephone.
