A:AnswerI don’t know specifically about AT&T, but I get caller ID through Verizon, and it works with that. I know that if I have to check the caller ID list, I need to use the silver menu button on the top left part of the phone.
A:AnswerYes, works with any provider. Great phone. I had purchased a couple for my home business back in 2010 and just now replaced them both. So lasting 12 years in my opinion is a great buy for the money.
A:AnswerI purchased the AT&T 2 Line Speakersphone because I can use a regular headset with its original plug-in. And, it makes a good connection with good sound quality.
A:AnswerI found the speakerphone quality to be excellent, both for the incoming call, and for the caller to hear and understand me. One of the better speakerphones I have ever heard, no hollow echo sound.
