Voice over IP (VoIP) has had a strong effect on global communications by allowing human voice and
fax information to travel over existing packet data networks along with traditional data packets. The
convergence of voice and data in the same network brings both benefits and constraints to users.
Among the several issues that need to be addressed when deploying this technology, security is
one of the most critical. We give an overview of VoIP and provide UML models of some aspects of its
infrastructure, including architectures and basic use cases. We present some security patterns that
describe mechanisms that can control many of the possible attacks and which could be used to
design secure systems.
