A VoIP phone, short for Voice over Internet Protocol phone, is a type of phone that uses an internet connection to make and receive calls, as opposed to using a traditional landline. VoIP phones can be either hardware-based or software-based. Hardware-based VoIP phones are physical devices that connect to your router or modem, while software-based VoIP phones are apps that you can install on your computer, smartphone, or tablet.
VoIP phones offer a number of advantages over traditional landlines, including lower costs, more features, and greater flexibility. VoIP calls are typically much cheaper than landline calls, especially for long-distance and international calls. VoIP phones also offer a wider range of features than landlines, such as call waiting, caller ID, voicemail, and conferencing. And because VoIP phones are not tied to a physical location, you can take them with you wherever you go.
