The most important issue for an IS auditor to consider with regard to Voice-over IP (VoIP) communications is the homogeneity of the network, because it affects the quality, security, and reliability of the VoIP service. Ahomogeneous network is one that uses a single protocol or standard for VoIP communication, such as Session Initiation Protocol (SIP) or H.32312. A homogeneous network can reduce thecomplexity, latency, and interoperability issues that may arise from using different or incompatible protocols or devices forVoIP communication12. Continuity of service, identity management, and nonrepudiation are also important issues for VoIP communications, but not as important as the homogeneity of the network. References: 1: CISA Review Manual (Digital Version), Chapter 4, Section 4.4.3 2: CISA Online Review Course, Module 4, Lesson 4
