I. Introduction to VoIP
A. Definition of VoIP
VoIP stands for Voice over Internet Protocol. It refers to making and receiving voice calls over the internet, instead of traditional analog phone lines. VoIP converts voices into data packets that are transmitted over broadband connections.
B. How VoIP works
VoIP phones work by converting sound waves into digital signals and compressing the data into packets for transmission over the internet using protocols like SIP, RTP, T.38 etc. At the receiving end, the packets are decompressed into audio signals again.
C. Benefits of VoIP over traditional phone systems
