Microsoft HMC 4.5 Drives CallTower's 2.0 Platform

San Francisco, CA, May 23, 2008 --(PR.com)-- CallTower, Inc., the leading provider Software as a Service based Unified Communications solutions for business, today announced that the company has set a release date for its next generation platform which will be built in conjunction with Microsoft’s HMC4.5 for integrated provisioning and billing for all facets of the solution.

The 2.0 platform will include upgrades and enhancements to the major core functionality including provisioning. The new platform will include Microsoft Exchange 2007, Sharepoint, Office Communications Server, Cisco CallManager 6.X, enhanced Unified Messaging integration and improved client facing provisioning. These new product enhancements will further separate CallTower’s offering from any other options available for businesses today. The new services are scheduled to be released in late July, 2008.

"CallTower's platform has evolved and expanded over the past six years. Microsoft’s HMC product allows us to extend an integrated platform to our clients with a single provisioning interface. Our internal technology team has done extensive work to extend the HMC platform’s abilities into Cisco’s CallManager, Microsoft’s OCS, Exchange, & Sharepoint products as well as all of the other services that we provide to our customers" said Bob Barnes, Executive Vice President of Business Development and Marketing, CallTower. “Business communication used to be about a phone and voicemail system; today employees are demanding more from their employers to help drive productivity. The integrated provisioning platform allows a small and focused IT team to simply deliver the most comprehensive communications solution to their company.”
