Today's business telephone systems are almost always based on Internet Protocol (IP) technology. It wasn't too long ago when all telephone system manufacturers exclusively used their own proprietary technologies and voice end points. That has all changed in favor Session Initiation Protocol (SIP), the open standard for communications.

SIP makes it possible for manufacturers of hardware and software to deliver unified solutions that are tightly integrated and eliminate the
proprietary islands of the past. And the consumers reap the
benefits. In fact, it is now possible for businesses to discard
their PBXs in the phone closet and subscribe to cloud
communications services and avoid investing in closet-
based equipment altogether.

Unlike closet-based solutions, cloud-based solutions require
no hardware to install, no software to buy and configure,
and no expensive training for additional in-house technical
support staff. This enables businesses to consolidate and
outsource their communications strategies for one
predictable monthly fee. Moreover, because the service
uses an open standard, businesses gain the flexibility to
integrate communications with their business processes
and workflows.

Ultimately the providers of cloud-based Unified Com-
munications services improve Total Cost of Ownership.
As you reduce your TCO, you eliminate the hassle of
coordinating multiple vendors, minimize cap-ex
investments, increase operational efficiencies, and
improve your bottom line.
