Unified Communications

Communicate and collaborate in a work anywhere world

Unified Communications Services

Unified communications (UC) are integrated solutions that bring multiple tools, such as instant messaging (IM), conferencing, email, and voice calling, together for seamless interactions with co-workers, partners, and customers wherever work demands.

Simplify how you deliver real-time communication and collaboration solutions to your enterprise. Log into one system for voice, e-mail, IM, and conferencing. Stay on calls that move between wired and wireless environments. As a cloud-based, as-a-service offering, we offer unified communications services that integrate multiple UC tools with presence behind a single user interface.
