SAN MATEO, Calif. -- Tello Corporation

--Tello Enterprise service is tested for compatibility with key Avaya IP telephony solutions

--Helps business users locate and collaborate with key contacts beyond their enterprise boundaries and across multiple platforms -- including phones, mobile devices and PCs

Tello Corporation, a provider of instant communication and collaboration solutions, today announced that its Tello Enterprise application is compliant with key Internet protocol (IP) telephony solutions from Avaya (NYSE:AV), a leading global provider of business communications applications, systems and services.

Tello Enterprise enables business users to quickly and easily locate, contact and collaborate with coworkers, customers, suppliers and partners in real-time across disparate networks, devices and applications. The Tello Connect hosted service platform, which provides the Tello Enterprise service to business users, is now compliance-tested by Avaya for compatibility with Avaya Communication Manager (CM 3.0.1) IP telephony software and SIP Enablement Services (SES 3.0).

"Achieving compatibility with Avaya IP telephony solutions will enable us to reach a wider range of enterprises and make deployments as easy as possible for our customers," said Tello CEO Doug Renert. "It will help us ensure that Tello Enterprise users are able to communicate more effectively with their business contacts at critical times."

Tello is a member of the Avaya DeveloperConnection Program -- an initiative to develop, market and sell innovative third-party products that interoperate with Avaya technology and extend the value of a company's investment in its network. As a member of the program, Tello is eligible to submit products for compatibility testing by the Avaya Solution Interoperability and Test Lab in Lincroft, N.J. There a team of Avaya engineers develops a comprehensive test plan for each application to verify whether it is Avaya compliant. Doing so ensures businesses can confidently add best-in-breed capabilities to their network without having to replace their existing infrastructure -- speeding deployment of new applications and reducing both network complexity and implementation costs.

"By offering compliance testing to the many innovative companies like Tello who are members of our DeveloperConnection program, Avaya promotes fully interoperable solutions that help businesses unleash powerful new possibilities," said Eric Rossman, vice president, developer relations and technical alliances, Avaya. "They are able to use Intelligent Communications to connect employees and customers to information from wherever they are, over whatever device they have available -- getting more out of their multivendor network and delivering new value to their bottom line."
