Answer:
Voice over internet protocol (VoIP)
Step-by-step explanation:
It is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.
VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter. In addition, wireless "hot spots" in locations such as airports, parks, and cafes allow you to connect to the Internet and may enable you to use VoIP service wirelessly.
