This document discusses pricing models for IP telephony and unified communications solutions from various vendors. It finds that: 1) Vendors like Avaya, Cisco, and Microsoft are evolving their licensing models from standalone to bundled pricing in an effort to simplify costs for customers. However, pricing complexity remains an issue. 2) A feasibility study is recommended to define requirements and success criteria before selecting a vendor solution to ensure alignment with business needs and strategy. 3) Competitive procurement yields the best pricing and support offers, though it requires more effort. Doing one's homework to understand each vendor's technologies, licenses, and total cost of ownership is important.
