    Not practical for everyday use.

    I work from home so my phone is very important to me. 1) Numbers so large that it spreads out the keypad and makes dialing uncomfortable. Had an AT&T model with smaller buttons that was a dream. Not this one. 2. Caller ID is slow and if you wait for it to show up, your caller may have hung up. 3. To scroll through the past call list, is cumbersome and requires several steps. It sometimes starts with the oldest first so it takes FOREVER to get through all the numbers. My last AT&T phone, you just pushed the down button and it let you scroll through them. 4. Voices come through very brassy. Often it sounds like another phone may be off the hook listening in but that's impossible in my case. 5. Loved my last AT&T phone except that the handset jack loosened and I had to keep it taped to keep a connection. I'm hoping this one isn't the same.

    Not the best phone

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    I bought this phone because I wanted call waiting, caller ID and a speakerphone all in one phone. The call waiting works beautifully. However, the speaker works fine on my end, but when you turn up the volume,I become distorted to the person on the other end. The speaker distance is way too short. I can only be a couple of feet from the phone, otherwise, the person on the other end cannot hear me. I also bought the phone because I am vision impaired. The picture on the web and on the box shows a light colored background with black print. The reality is the background is light blue with medium blue print. That's when it is lit. When it is not lit, it is simply a dark screen. Caller ID is worthless to me, because I cannot see the screen. Even if the screen can be changed to another color, I couldn't see to change it. Not happy with this purchase.

    Not as advertised


    Best Buy on-line description: 2-line operation; caller ID/call waiting; caller ID announce; digital answering system; 3-party conferencing; speakerphone; data port. Stated above is the BB description of a "digital Answering system", the reason I purchased the phone in the first place. I bought it as an all in one system for my mother as a gift a few weeks ago to give today. When setting it up, I poured over the instructions for about an hour trying to figure how to set up the answering machine & there was none. The conversation in trying to return a phone that wasn't as promised was painful. Moral of the story, understand that there is a 15 day window from time of purchase; don't buy gifts unless you're giving them that day & your gift recipient tries out said gift in front of you!

    Good phone, but call history feature is inadequate

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    The overall features of this phone are good, but I am not satisfied with the call history feature. Before purchasing this model I used an ATT 825 speakerphone with a separate caller ID box. If the green light on the caller ID box was blinking, I was alerted that someone tried to call. After many years of reliable service, the caller ID box needed replacement because the display was fading. I opted to replace this with the ATT 17929 phone with a built in caller ID. This is my main phone, but I have a separate answering machine. The problem is that when the phone rings and the answering machine is activated, the screen does not show this as a "new call" to be reviewed, because it has already been responded to by the answering machine. Therefore, I am not aware of any new call activity unless I make the effort to see if there were any recent entries to the call history log. It was so much easier in the past to glance at my caller ID box and look for the blinking green light.

    UNUSABLE phone!


    WORST PHONE EVER! If I could have given 0 stars, I would have! First, we bought the now-discontinued ML17928. The line (either one) make a clicking noise and cut out. The phone incorrectly dials numbers, even though the display shows the right number! The phone is UNUSABLE. BestBuy refused to take it back. We contacted AT&T and they refused a refund, so they sent us a replacement, the ML17929. Did the exact same thing. We even tried a different phone from our house in the office and replaced the phone line wires. Did not matter. AT&T tried to say that the clicking was from people talking on speakerphone at the same time. IT WASN'T.

    Works fine

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    I purchased the AT&T 2 line phone to run a small home business. I needed a phone with the headset capability directly from the phone. After reviewing many other phones, I found this one to be the best for the intended use. It's not the best but serves it's purpose as a basic corded phone line with headset capability.

    Awful speakerphone quality


    After using for the phone for an extended period, I can conclude that the speakerphone has terrible quality. I have had multiple instances with a variety of callers who have complained that the speakerphone is clipping the making the speech on my end almost not understandable. Going to the handset solves the problem, which confirms that the speakerphone quality is a major issue. Again, many times and all the time, with different callers. So since I need to use the computer and talk at the same time, this office phone is really useless.

    Great Phone espeically with a Headset


    Good product. Great audio quality. Great volume. Also, and this was key for me, it can switch from a headset to the speakerphone by pressing a button. Good price I had a Panasonic KX-TS880B (which only has one line), but chose to replace it partly to add a second line, but especially because the Panasonic requires pulling the headset out to use the speakerphone, which is really not acceptable. The AT&T phone is much better.
