Voice and Collaboration

Business can thrive when everyone works together. AT&T brings together your voice communications and the collaboration features you need. Voice over IP (VoIP) delivers traditional voice capabilities with the ability to add on features. Communicate using voice calling, instant messaging, presence, email, conferencing (video, Web, and audio), single number reach (one number reaches you at any device), and unified communications federation (cross-platform communications).  

When people can work together, nearly anytime and anywhere, productivity and innovation can flourish.
