The AT&T 993 2-line corded speakerphone is the perfect solution for a small business in need of a phone with two line support. The speakerphone in the base station allows hands-free communication and the party conferencing features lets you conduct business with up to three participants. The automatic line selection feature will connect you to the incoming caller instantly. With the 993 you can also assign a different ring tone to each line. A large display provides easy-to-read text for setup and caller information. The phone has a 100-entry memory and a 99-name-and-number caller ID history. Numbers stored in the caller ID history can be dialed directly and, with the call waiting-capable caller ID component, you can see who is calling even when already on the line.
