ATLANTA (Dec. 5, 2005) Cingular is enhancing the way businesses and consumers communicate as it introduces a next generation Push to Talk (PTT) service. The service will operate across the largest Push to Talk coverage area in America, and brings a host of new, unmatched features including:

• Availability? unique icons allow Cingular PTT users to see if other PTT customers are available before making a PTT call.
• Quick Group Calling ? allows users to select individuals from their contacts and instantly place a group call. In addition to this impromptu group calling, customers can also pre-establish groups in their contact list (up to 30 groups) and call up to 20 people.
• Convert to Cellular ? enables a PTT call to be converted to a regular wireless voice call. Calls with up to 20 participants can be converted effectively creating a mobile conference call.
  ?We've gone the extra mile to offer our customers an innovative service that truly combines the best features of wireless and PTT, and in doing so, set a new benchmark for the industry,? said David Christopher, vice president of consumer product development for Cingular. ?The unique features and attractive pricing offer consumers an overall value unmatched by any other national PTT service.?

By integrating walkie-talkie and traditional cellular technology, Cingular provides a refined PTT service that can be used by families, executives or employees at job sites. With one click a PTT user can access their list of individuals and groups and see who is available and who is not. One more click and they are instantly speaking to the person or the whole group (up to 20 people). If a quick PTT call turns into a longer discussion, simply convert the call to cellular. In addition, the service offers:

• Call Waiting ? gives customers the option to accept or decline a second incoming call whether currently on a PTT or regular cellular call.
• Contact Alerts ? lets customers receive alerts when a contact becomes available.
• Voice Messaging ? leave a voice message with one person or a group of people directly in their current cellular voicemail box.
• Call Me Alerts ? allows a user to urgently let someone know they need to talk. A user receiving a ?Call Me Alert? can instantly place a PTT call back by pressing the dedicated PTT key.
  The service also uses a single phone number for both cellular and PTT service, eliminating the need to remember two numbers.

?Cingular is taking the walkie-talkie service that is so important to blue-collar workers and adding wireless features to make it just as valuable in the white-collar world,? said Joe Lueckenhoff, vice president of business services for Cingular. ?The flexibility of converting a call to cellular, letting people know your availability and quickly conferencing groups together, gives business users a real alternative to how they currently use PTT.?

?Cingular took their time and got it right. The company recognizes that Push-to-talk is just the jumping off point for adding a series of value added voice services that will appeal to both existing PTT customers as well as an entirely new set of customers,? said Andrew Seybold, president of Outlook 4Mobility, a well-known consultancy firm. ?Value added voice services, including PTT will provide them with a competitive edge across many different market segments. I expect that teens, who prefer to talk in groups, will quickly adopt this PTT service as their own form of voice instant messaging.?

These features offer unlimited minutes, national coverage and no hidden charges for group or national calls. Consumers on a Cingular Nation Plan can add service for $9.99 a month per line.
