Voice over Internet Protocol (VoIP) is an evolving telephony solution that brings voice and data traffic together on the same IP-based network. As a result, VoIP is becoming an increasingly appealing alternative for more enterprises seeking to gain cost efficiencies and enhanced features. Enterprises wishing to exploit the advantages of switching voice calls to the IP network must understand that maintaining security of those packets is an integral part of the overall VoIP deployment. Focusing on quality of service and throughput is certainly important, but ensuring the integrity of voice transmissions and guarding against malicious activities and access is crucial to the success of the evolving solution.
