Answer
Both A and R are true and R is the correct explanation of A.
Explanation
VoIP stands for Voice over Internet Protocol, and it is a technology that allows us to make voice calls using a broadband connection instead of a regular phone line. The voice calls are first digitized, compressed, and then fragmented into small packets, which are then relayed by Internet Protocol (IP) across the network.
