IP Telephony offers some dramatic benefits over Traditional Telephony in the areas of portability, and accessibility. These enhancements do not come without a cost and require greater effort, planning, and vigilance to ensure high availability and security. “Most users implementing VOIP these days are primarily concerned about voice quality, latency and interoperability”1 rather than security. Many are “preoccupied with simply making it work.”2 When implemented within an overall security mindset, IP Telephony can successfully address key business problems. It has the potential to dramatically increase the competitive effectiveness of a company and increase shareholder value.
