Encryption plays a major role in achieving privacy, especially in communications and information systems such as military systems, banks, telecommunications and individuals, and in mobile phone networks in particular. The (GSM) standard provides a level of privacy that may not be sufficient for some users, as this study is presented a proposed system for applying audio coding in cellular communication networks from the beginning (mobile) to the end (mobile (via the standard mobile communications system) GSM), and in this standard is used the A5 algorithm for audio coding is only for transmitting stations, while for the rest of the network it is without transmitting coding the data as it is, so we in this study proposed the application of RC4 algorithm with A5 algorithm through encryption keys controlled by the sender and receiver in audio coding from start to finish to ensure complete encryption and privacy in network phone calls and the tool used in this the research is a matlab program to create a simulated environment for the transmission between the sender and the receiver to add the RC4 algorithm for these stages and one of the results of the study using the RC4 algorithm in the transmission model in the telephone network can achieve greater privacy in telephone calls communication without affecting the sound quality through the two encryption keys controlled by both ends connection.
