What does IP mean ...?

  • An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.[1] An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."

What does it mean to have a “cloud-based telephone system” ... ?

  • It’s designed for organizations needing robust communication features without having to own and maintain an on-site telephone system. The central intelligence of the telephone system resides in a service provider’s secure data center. All you have to buy or lease are the end-user devices—such as phones and routers—and the local area network (LAN) to connect those devices to the provider’s IP network. You simply pay a monthly service fee based on the number of users and the selected calling plan then all you have to do is answer your phone calls utilizing the unified communication applications your business needs.

What is UC ... ?

  • Office phones, cell phones, voice mail, email, videoconferencing, instant messaging and more… your organization has many ways to connect with employees, customers and business partners. But if all those channels work independently, the communication system isn’t delivering all the value that it could. Unified Communications bring it all together for more natural, productive and effective collaboration and customer care.
