A VoIP phone uses Internet protocol technology to send and receive calls. It is used with a VoIP phone system or service. A wireless VoIP phone frees the user from the constraints of a wired device. The user can move around freely while sending and receiving calls in home or office. This type of phone system has two parts – a built in WiFi receiver unit which is connected to the base station or an access point. There are some important things to consider when buying such a phone. Every organization has different set of needs. The selected VoIP phone should meet specific requirements of the user. The phone must have standard features like call waiting, conferencing, call parking and call transfer. It should have a large display and a good speakerphone. The buyer must know how many incoming calls will be received at a time. The phone should be able to handle that many lines simultaneously.
