ESI announces interoperability with Clearfly

Plano, Texas, and Billings, Montana, January 3, 2011

Estech Systems, Inc. (ESI), an innovative leader in digital and IP-based phone systems, and Clearfly Communications™, Inc., an infrastructure-based provider of unified communications solutions, today announced that ESI Communications Servers have been certified with Clearfly’s Clearphone™ services. ESI Reseller customers in Clearfly’s service area can enjoy the many benefits and opportunities offered by combining an ESI phone system with Clearphone SIP trunking.

“Clearfly and ESI technologies work together to give customers the ability to simultaneously optimize their communications and save a significant amount of expense,” said Chris Hunter, North American Sales Director for Clearfly Communications. “Our Clearphone service easily connects to the customer’s network and integrates directly with ESI’s phone system. The transition to SIP trunks is virtually invisible to the user and allows customers to maintain all their current phone numbers.”

When an ESI Communications Server and Clearfly service are used together, businesses and organizations will enjoy an affordable and scalable IP communications solution. Users save money on their phone services; and, in many cases, the savings exceed the cost of the phone system.

ESI Communications Servers are compact and powerful, delivering standards-based technology in a flexible, easy-to-use, and cost-effective package. Clearfly provides small-to-medium business customers with reliable, high quality, integrated service packages that include local, long-distance, Internet access, and SIP trunking services throughout the United States.

“Clearfly offers ESI Communications Server users a reliable, cost-effective new choice for SIP trunking,” said Doug Boyd, ESI’s President and Chief Operating Officer. “ESI customers will appreciate the reliable, high quality services available from Clearfly, and we are pleased to offer Clearphone SIP Trunking services to ESI customers via our nationwide network of Certified ESI Resellers.”

Customers select the ESI Communications Server which meets their needs now and for years to come. ESI Communications Server models, from the ESI-1000 to the ESI-50, vary primarily by their call-handling capacity, so IP communications solutions are available to small-to-medium sized companies.

Clearfly’s Clearphone services come in flat-rate data and voice packages with unlimited long distance and are specifically designed for the needs of small and medium businesses. Clearfly services are delivered through a single connection with domestic local and long distance as well as international calls to Canada included in the base rate, giving customers savings of up to 30 percent in their monthly telecommunications expenses.
