Voice over Internet Protocol (VoIP) an emerging new technologies is based on realtime communication of data by sending and receiving digital signals using Internet Protocols (IP). VoIP has become popular in business organization and scientific communities. Voice coder (Codec) named as coder and decoder, play an important role in packet switch network for transfer of audio and video data. A signalling protocol known as Session Initiation Protocol (SIP) is used for data communication between nodes in VoIP network. In this paper we survey on security related issues in VoIP communication system and covered several security attacks. We proceed with survey on all the problems that have big effects on VoIP security and challenges such as data manipulation, substitution attack, power backups, jitter, latency and delay. Finally, we conclude the paper with further research on security of VoIP communication system.
