VoIP is a technology that allows to communicate with use communication lines on a network. VoIP refers more to voice communication. I am utilizing VoIP as a voice communication channel with voice as a medium for inserting secret messages. The research results that steganography techniques can be used with VoIP. By inserting a text message that is first encrypted and then entered into sound by the Least Significant Bit method. The test results, the Alpha testing, and Beta testing, resulted in a percentage above 90%.
