• Pay Per Call Technology to Enable AT&T to Lead in Growing Performance-based Advertising Trend

SAN ANTONIO, December 10, 2007 —

AT&T Inc. (NYSE:T) announced today the completion of the acquisition of Ingenio, a leading provider of Pay Per Call® technology. The combination will allow AT&T to better serve business directory and local search customers across its entire advertising and publishing portfolio. AT&T plans to quickly begin integrating Ingenio within AT&T's YELLOWPAGES.COM, and the organization will be overseen by Charles Stubbs, president and CEO of YELLOWPAGES.COM.

Integrating Ingenio's Pay Per Call solutions into AT&T's suite of offerings for advertisers will allow AT&T to provide additional options and tools for businesses to manage their advertising programs. The technology will provide an alternate performance-based lead generation tool for businesses that want to reach customers.

"AT&T remains committed to providing advertisers with comprehensive solutions," said Ray Wilkins, AT&T group president-Diversified Business. "The addition of Ingenio's capabilities will give advertisers the flexibility to easily manage their advertising needs across all platforms--online, mobile and print."

The transaction is expected to have minimal impact on AT&T's results, including earnings per share.

The addition of Ingenio's services further enhances AT&T's portfolio of directory and local search offerings. YELLOWPAGES.COM and AT&T Real Yellow Pages deliver unsurpassed visibility and value to advertisers. AT&T delivers print directories to more than 83 million residences and businesses in 22 states and has a premier online presence nationwide with the YELLOWPAGES.COM Network. Together, these products receive more than 5 billion consumer searches a year for local business information and provide more than 1 million advertisers with valuable sales leads to help their businesses grow.
