P network architecture is fragile from security point of view, and Voice over IP (VoIP), which uses the standards of this network, is vulnerable to multiple attacks that reduce the quality and, in some cases, disconnect services and waste VoIP resources. In this regard, VoIP security is essential, and typically the implementation of security solutions in systems such as VoIP will slow down and reduce the quality of performance and increase the costs of upgrade and maintenances. Therefore, IT managers should consider high-security security solutions. To do this, by reviewing the research literature, VoIP comprehensive security matrix has been extracted from a comprehensive list of VoIP security challenges and coping strategies that make a significant contribution to the intelligence and risk management of organizations. The results obtained showed that the implementation of 3 strategies including "Separation of Voice and Data Traffic VLANs", "Signaling Authentication" and "Port Authentication" would have the most positive impact on Amin Police University VoIP security. The results are consistent with the recommendations and security countermeasures mentioned by previous research and security institutions, and only the proposed priorities are different. Therefore, in strategic IT planning, decision making, and supervision of IT managers, the three mentioned strategies should be considered as a priority for VoIP applicationIP network architecture is fragile from security point of view, and Voice over IP (VoIP), which uses the standards of this network, is vulnerable to multiple attacks that reduce the quality and, in some cases, disconnect services and waste VoIP resources.
