The document summarizes plans for Harvard University to transition from traditional desk phones to a unified communications system that provides modern communication and collaboration tools. It discusses how calling behavior is changing as mobile device usage increases, and how the current phone system is nearing end of life. The initiative will implement an IP telephony platform in 2015 to provide features like soft phones, conferencing, messaging and video on various devices. This aims to reduce phone infrastructure costs while improving mobile access and empowering users with self-service tools. Several challenges and opportunities are outlined, including transitioning users, operational changes, and coordinating the multi-phase rollout across Harvard's schools and departments.
