What is a VoIP Phone?
A VoIP phone is a type of telephone that uses Voice over IP (VoIP) technology to make and receive calls over an internet connection.
VoIP phones can be hardware or software-based, offering users a range of features such as inbound and outbound calling, SMS texting, call controls, routing capabilities, and other advanced digital functions.
The following devices can act as a VoIP phone:
- Mobile devices
- Computers
- Tablets
- VoIP hardware–headsets and desk phones
How Does a VoIP Phone Work?
VoIP phones transmit voice data via the Internet, instead of the public switched telephone network (PSTN). VoIP technology converts analog audio sounds into digital data packets, which travel via broadband Internet from your local WiFi network to your VoIP phone service provider. Your VoIP service provider then uses an IP PBX (private branch exchange) system to transmit the digital data over the internet directly to another VoIP provider, who routes it to the recipient.
