San Francisco, CA, March 27, 2007 --(PR.com)-- CallTower, Inc., the leading provider of hosted communications and collaboration solutions, today announced that the company will demonstrate how Charter Schools can reduce capital expense, increase communication, collaboration and community interaction as a result of using CallTower’s IP Communications services, at the 14th Annual California Charter Schools Conference, March 27-30 at the Town and Country Resort & Convention Center in San Diego.

The information will be presented in company sessions at booth number 719, and interactive conference sessions throughout the California Charter Schools Conference.

CallTower executives will present success stories and information gathered from successful CallTower Charter School and Non-Profit Organization customers, who are now using CallTower’s hosted, advanced voice and data suite with true Unified Communications to achieve higher levels of productivity, communication and community support.

Non Profit Organizations Benefit From Advanced Communications Technology and Features
As telecommunications and messaging costs-per-employee are rising, most not-for-profit organizations are experiencing challenges in how they efficiently manage the growing IT infrastructure demands of email, voicemail, fax and other client support services, as well as the capital expense to deliver these new technology solutions.

CallTower provides solutions to solve support and organizational challenges that previously required additional human resources. CallTower transforms an organization’s communications processes into a competitive advantage that allows these groups to be more successful in today's marketplace. As a result,

CallTower allows Non-Profit Organization workers to communicate with, support, and service their donors, stakeholders and constituents better.

CallTower empowers qualified non-profit groups with affordable, hosted, advanced IP-based voice and data services that in the past were only available to Global 250-type companies. These services and applications include: hosted voice, data and network services, all Internet, email and fax messaging, Microsoft® Exchange and Microsoft® Live Communication Server integration, presence management, calling plans, network administration, single-wire connectivity, call center functions, disaster-proof access to all data and voicemail, and 24/7/365 U.S.-based customer support.

CallTower’s advanced set of hosted voice, data and services eliminate the ongoing maintenance and service costs of managing on-premise telephony, Internet service, and data systems.

“Charter schools and non-profit organizations can immediately obtain all the features and functionality that will allow them to better communicate, collaborate and more efficiently support their students, faculty and staff, parents and community,” said Mark Harris, Executive Vice President of Sales and Marketing for CallTower. “CallTower is committed to developing secure, Always-On applications that improve the productivity of knowledge workers – both within a business or a not-for-profit organization. With CallTower, non-profit organizations – like their business counterparts – can virtually eliminate their capital expense for telephony and data, add collaboration and communication applications, and immediately deploy and benefit from all the features and functionality.”
