In this sense, the new CAESMA model is proposed, which appears to cover the shortcomings noted<br />

in the forensic models previously mentioned, meeting all necessary steps for a proper VoIP forensic<br />

analysis, as established in the DFRWS general model.<br />

VoIP traffic, which ultimately will provide us with validate evidence for an adequate use by judicial<br />

authorities.<br />

validation for an adequate VoIP network analysis.<br />
