The Internet was once a small world. However, an innumerable number of network nodes are now connected to personal computers and their servers. When Voice over Internet Protocol (VoIP) services became widespread, VoIP topology and infrastructure became vulnerable to attackers who attempt to gain access to VoIP servers. These attacks on VoIP servers are a serious concern. While cryptography has been used for thousands of years to secure messages during wartimes, today we face cybercrime hackers who attempt to crack public or private encryption keys using a wide range of tools and mathematical clues. Their aim is to break down the cryptographic algorithms that protect VoIP servers in order to get three things: calls, user client privileges. The previous research on VoIP security is insufficient to address the increasing number of attackers. The current research aims to secure packet telephony by using cryptography to increase confidentiality and enhance the crypto mathematical approach in order to reduce the cost of high encryption techniques. This paper intensively studied cryptographic usage, concentrating on public and private keys (though the former are more commonly used). Thus, this paper presents a basis for further research on VoIP encryption.
