The university is currently using Cisco WebEx for our UC services. Unified communications (UC) is an umbrella term for the integration of multiple enterprise communication tools -- such as voice calling, video conferencing, instant messaging (IM), presence, content sharing, etc. -- into a single, streamlined interface, with the goal of improving user experience (UX) and productivity.
