Abstract: Nowadays mobile communication is changing its definitions from a global system for mobile communication (GSM) and code division multiple access (CDMA) communication mechanism to internet-enabled communication mechanisms. In GSM and CDMA technology mobile phone users have to depend upon local service providers. Sophisticated criminals are also aware of the law enforcement agencies' tactics for GSM/CDMA-based call investigations. VoIP is a voice over internet protocol, an internet-based calling mechanism. VoIP is one of the solutions used by sophisticated criminals for hiding themselves from the ordinary communication mechanism and is an internet-based calling service. In this research, the methodology is discussed and implemented for the identification of VoIP communication using network packet capture and monitoring. This research will cater to the needs of VoIP investigations using network-based packet capturing, analysis and investigation.
