In our 29-criteria evaluation of unified communications and collaboration (UC&C) providers, we identified eight of the most significant ones — Alcatel-Lucent (ALE), Avaya, Cisco, Microsoft, Mitel, NEC, ShoreTel, and Unify — and researched, analyzed, and scored them. This report shows how each provider measures up and helps application development and delivery (AD&D) professionals make the right choice.
