Due to its many advantages, VoIP is nowadays replacing the traditional analog communication. Although it is a promising technology, it suffers from a big disadvantage that makes wire tapping or sniffing much easier. The only counter-measure is encryption. Many companies provided plenty of products to minimize the chance for sniffers to receive readable packets. Unfortunately, those chances are minimized but not yet eliminated. Low enforcement agencies and the products' manufacturers are still capable of penetrating. In this article, we provide a way through which VoIP communication will be encrypted using a user-defined dictionary. The purpose of this article is to show to what extent such an idea can provide sufficient immunity.
