AT&T Completes Interwise Acquisition

Launches Converged Conferencing Service as First in Comprehensive Portfolio of Unified Communications Solutions for Companies Worldwide

AT&T Inc. (NYSE:T) today announced the completion of the acquisition of Interwise, a leading global provider of Internet Protocol (IP)-based voice, Web and video conferencing services. In parallel, AT&T announced the launch of AT&T Connect™, the first in a planned series of converged AT&T-branded voice, video and web conferencing products and services that will accelerate the delivery of unified communications to companies worldwide.

With the introduction of AT&T Connect, the company is advancing its focus on delivering a comprehensive, global portfolio of unified communications solutions. The demand for such services is expected to total $5.9 billion in 2007, with continued growth expected in 2008 and beyond (source: Frost & Sullivan).

“With the capabilities of Interwise integrated into AT&T’s industry-leading global IP-based network, we’ve got the reach, scale and customer base to quickly deliver to businesses what other players can only promise in the unified communications space,” said Ronald E. Spears, group president, AT&T Global Business Services.

“We believe that our IP network is the lynchpin to delivering a rich set of unified communications capabilities at the scale needed by enterprises operating in global and dynamic environments.”

“Unified communications will improve how people work as a result of their ability to enable more effective collaboration among distributed project team members and to reduce process time for key business activities,” said Frank Zvi, vice president, AT&T Unified Communications. “Over time, AT&T’s Unified Communication Solutions will enable businesses to leverage the power of communications to create more agile, effective organizations and to connect their employees, partners and vendors in a manner that suits them wherever they are and over any device — wired or wireless, PDA or personal computer.”

AT&T is rapidly integrating its wired and wireless network assets, over which it intends to deliver a portfolio of services to help businesses integrate all of their communications applications — wired and wireless voice services, conferencing capabilities, including VoIP, Web and video, and presence-based applications, such as instant messaging and directories.

Communications is the basic component of commerce, and collaboration has become mission-critical for today’s enterprises. Businesses are using their combined software and communications networking capabilities to drive decision-making, swiftly react to their competition and use the inherent productivity and cost-savings returns of collaboration tools to invest in furthering their core capabilities.

AT&T’s enhanced solutions are designed to bring the broad benefits of collaboration to where they matter most by enhancing enterprise’s ability to compete more effectively while improving the bottom line.

AT&T’s first unified communications solution is AT&T Connect, a converged IP conferencing service that provides unlimited voice, Web and video conferencing capabilities and can be scaled for businesses of all sizes. In addition to offering on-premises and fully hosted conferencing capabilities, AT&T will now be able to offer a unique, hybrid solution that allows enterprises to receive the cost and security benefits of on-site software with the rapid startup, geographic reach and capacity protection of its hosted service.

The company intends to integrate its existing award-winning portfolio of voice, Web and video conferencing services with the capabilities it gains from the Interwise acquisition by the fourth quarter of 2008. Existing AT&T conferencing and messaging services will be key elements in AT&T’s ongoing development plans to deliver expanded unified communications solutions.

In October, the company said it would acquire Interwise for $121 million in cash. With today’s announcement, Interwise joins AT&T’s existing enterprise services organization as a subsidiary of AT&T Communications Corp.
