Top cloud-based telephony and UC providers

Ring Central Inc. specializes in cloud-based business phone systems that incorporate business SMS, conferencing, conference calling and mobile apps under a single technology umbrella. There's even a Web phone to permit users to call out from the system when away from the office over the Internet, and to support a direct call to a targeted individual with a single mouse click. What's missing is built-in UC support, though connectors for Outlook and SalesForce.com are available added-cost options. The Ring Central offerings get such rave reviews from happy adopters, though, that we had to include it in our shortlist here.
