  1. Answering machine has failed after a year Review by Patricia
    Overall Satisfaction

    The phone itself has been fine, the clarity is better than the one I had previously. The captions are as most have described, an unbearably long delay while trying to carry on a "normal" conversation. My biggest problem is with the answering machine. It worked fine up until about a week ago when callers could no longer leave a message, it disconnects before the answering machine engages. I spoke directly with customer support (no help other than she'll let the development team know), emailed them also and so far, no reply, no resolution. I paid for this myself even though I am entitled to receive a free phone. I am nearly completely deaf and job searching right now, so an answering machine that captions is vital for me. Very disappointed in the lack of response from these people. (Posted on 3/7/2018)

  2. Great Product Review by Frank
    Overall Satisfaction

    This is a replacement of an older Captel phone. A touch screen is more in line with modern technology. The screen is also bigger for the captions. I highly recommend this newer version. (Posted on 12/11/2017)

  3. Not right phone Review by Wrong
    Overall Satisfaction

    The description of this phone and how it works was not complete in the magazine ad and it is not the right phone for me. I don't need captioning like this. Ad implied it was automatic, not a person doing it. You were going to send me a catalog and reimburse the payment. I have received neither as yet--over a month ago! (Posted on 11/19/2017)

  4. Slow, inaccurate and not loud enough Review by cook
    Overall Satisfaction

    The script is slow enough that it doesn't help while talking. It does help to review later. However, it often doesn't pick up the same words I can't. I programmed my audio graph in as directed but can barely hear at max volume,with hearing aids in. I would appreciate any advice.

    **Captioning speed is dependent on the speed of the internet, sometimes having a direct connection to internet will fix the delay as opposed to using wifi. CapTel has a technical support department that could assit with these issues. - Harris Communications** (Posted on 8/7/2017)

    Overall Satisfaction

    It is all and more than I hoped for......does fairly much all the work for you at the touch of a button.
    Still titrating the handset volume.

  6. like it Review by Pat
    Overall Satisfaction

    This second caption phone does more that the one the state gives . It is my communication . Coleen did a wonderful job of setting up the phones to the best and easiest use for me . This one has an answer service Very pleased. (Posted on 7/10/2017)

  7. better than nothing but not great Review by Daughter
    Overall Satisfaction

    The concept is great but the delay from the time something is said until the time it appears on the screen is about 20 seconds. When you are trying to have a conversation, this is an unbearably long period of time for the person receiving the print out to have to wait. Going to try an amplified phone for my 96-year-old mother.

  8. Outstanding Review by Bill T
    Overall Satisfaction

    Works like a champ. Calls come in but are negated after 1 ring.....some calls still need to be zapped with red button but they don't recur. (Posted on 6/15/2017)

    Overall Satisfaction

    The ringer doesn't work. Hear the test ring but doesn't ring. Volume not loud enogh. Caption is good.

  10. Allows communication where there was none before Review by Richard
    Overall Satisfaction

    It works as advertised. My sister and I have had several conversations with my Mom where she was able to understand (via reading the captions) what she could not discern before.

    It does take a bit of getting used to. For both Mom to look at the screen and for the caller on the other end to pace themselves - not adding comments until Mom had read and responded.

    But that seems like something that just will take a bit of time and it will be fine. (Posted on 3/14/2017)

  11. Good phone but two problems Review by Terry
    Overall Satisfaction

    I have had three captioning phones, CaptionCall, which developed a feedback echo of my voice that they were unable to fix (even though initially it did not have this problem so it had to be due to a software update) Clarity Ensemble, (which prevents you from making any phone call except 911 if your internet connection is down, even though it once had that option as other phones do, again a software update that is dangerous IMO) My third phone, the CapTel 2400it was very easy to set up, and while I didn't need it they offer excellent tech help via a direct button on the phone. I love the features compared to my previous phones. Large and attractive screen and good graphical interface, but also a button keyboard instead of all touch screen. I like that. All captioning has a delay, and none of it is perfect, but on the Captel, if a word is not correct the system apparently tries to correct it then puts the original mistake in brackets. This has not happened yet as the captioning has been quite good. My problem with this phone is that I am again getting a feedback loop echo of my own voice, which seems to vary, sometimes not there, sometimes really bad and covering up the caller's words as far as hearing what is said. Tech support told me I have the volume too high (?) and that is why it is happening. So why not on the Caption Call? And why advertise a decibel level that does not provide clear sound at the highest ranges? Those of us who are not totally deaf, also want, and for that matter need to hear as much as possible, which the tech person argued was not necessary on a captioning phone (?) The other problem is a 3.5 headset jack when most if not all the connectors for headsets are 2.5. The adapters cause line noise, crackling, whistling when they work at all. This feature needs to be changed to a 2.5, or a quality adapter included. I have ordered a bluetooth headset with a volume control in the hopes of solving both problems because I really like everything else about this phone. (Posted on 1/24/2017)

  12. Not great for hearing challenged people Review by dancerbob
    Overall Satisfaction

    Handset works ok, but not great; very precise positioning to engage telecoil. Speaker: terrible; its located under the machine, is difficult and muffled to hear. The microphone: others cannot hear, have to switch to handset for them to hear conversation. Bluetooth: frequently needs to have phone disconnected, re-setup, and re-paired to use; can't leave engaged, as it interferes with Bluetooth through neckloop for TV viewing. Captions work ok. Built in answering machine: can't answer by speaker or call is disengaged and anything already recorded is erased. No follow-through from customer support. (Posted on 12/21/2016)

  13. Great! Review by Gina
    Overall Satisfaction

    Self setup was fairly easy. Remember to put a country code as in 1 for US :) to ensure calls reach area codes outside of your own.

    I wasn't expecting to get an email from Hamilton asking further questions before shipping, which caused a bit of a delay in receiving it. So new customers should keep an eye out for these. (Posted on 12/14/2016)

  14. Microphone Volume Review by linspokne
    Overall Satisfaction

    I bought it for the Bluetooth capabilities which work well and the answering machine capabilities. As such, I use the speakerphone mostly but have to shout at the phone to be heard. Per the manual, there is no adjustment on just shows how loud you are speaking with the curved loudness lines....which never go to max even when shouting. And where is the microphone anyway?

  16. Way Better Then Expected Review by Bren
    Overall Satisfaction

    Purchased the 2400i BT and so far it is way way better then all the other 3 cap tel phones I've used. My husband likes it too. I don't think you ever really get a "Perfect" cap tel phone but it does work very very well and we are satisfied! I highly recommend this cap tel phone. Be patience and learn to get the hang of it. It's pretty simple. Makes our lives easier. (Posted on 10/12/2016)

  18. Fantastic Review by Tim
    Overall Satisfaction

    So far the phone is fantastic. Surpasses any thing that I was expecting. But the best part was the Outreach Representative, Claire Grothe, who deserves a pay raise. She was delightful, polite, knowledgeable and above all, professional. She alone make this a most pleasurable and satisfying experience. Thanks again for a fantastic product and a wonderful representative. (Posted on 6/22/2016)

  19. happy w/ phone, but instruction & commun. was sub-standard Review by satisfied daughter, but...
    Overall Satisfaction

    When you buy a product and have it shipped 2,000 miles away to your mom, and the product's representative calls you to follow-up on your purchase, that seems pretty nice. And, when the product rep. says they're going to follow-up with your mom's care-giver to make sure that all will be well when the phone is set up, the service seems too good to be true, but you like the sound of the promise a whole lot. Well, the young man never called my mother's care-giver and we went thru 6 weeks of "the phone works, the phone doesn't work". The care-giver is not technical oriented, my 94 year-old mom isn't technical oriented and it was very frustrating for me to sit 2,000 miles away being told on alternating weeks that the phone worked or it didn't. I called Harris, but the was told I had to talk to the company that actually fulfilled the order--that was quite frustrating. Also, the fulfillment company stated that they were open on Saturdays--they printed their time-zone and numbers to call on Saturdays so I followed precise instructions, but they didn't answer their phone on Saturday--when I called on Monday, they said they don't work on Saturdays so I asked, "why does your website state that you can call on a Saturday?!?" more frustration... Finally, after 6 weeks, the care-giver figured out that the words appear on the screen ONLY when my mother was the FIRST person to answer the phone in the house. If someone else answered the phone in Mom's house on a traditional phone and then walked into Mom's room to tell her to pick up the phone, the words would NOT appear on the screen. But, if Mom answered the phone first, the words WOULD appear. Ah Ha! We got it figured out, but we had to go thru 6 weeks of pain!! Why doesn't Harris put that instruction in BIG print all over their shipping materials??? But, the phone now works consistently!! All's well that ends well. (Posted on 5/15/2016)

  21. satisfied with phone Review by filly
    Overall Satisfaction

    Purchased phone for our mother who before always handed phone over to someone else to handle the call for her since she couldn't understand what the caller was speaking to her....well what a 360... she now keeps the phone ...its such a delight to see her enjoy phone calls again and be able to conduct the phone call herself...Its been a few days now and I've not had to handle one phone call for her...She caught on quickly how to work the phone and she loves the design and features...she can also hear a lot of the conversation as well....the captioning is a bit slow but she still is in control of the phone call by just telling someone to slow down their speech a bit if far its been a good purchase and life changing for her. (Posted on 11/17/2015)

  26. Easy to Use and Install Review by Dick
    Overall Satisfaction

    This actually exceeded my expectations. Excellent documentation.
    The installation was a breeze. Like any new technology, it takes a little time to get used to it. The touch screen is very responsive and the menus are easy to understand. I highly recommend this phone. My only problem which has nothing to do with the phone, is dealing with my hearing deficit. This phone really helps. (Posted on 4/1/2015)

  27. worth every penny I spent on it Review by Tom
    Overall Satisfaction

    This phone is a must have for those of us that have a hearing loss that makes using a regular phone nearly or totally impossible to use. Gone are the days when you had to say go ahead after each party was through saying something this is truely a 2 way system and is more like using a normal phone and a plus for this phone is a hearing person can use it as long as the captioning is turned off so that it doesn't use a relay service that is reserve for the hearing impaired and deaf to use.

  28. Communication What a Joy it is to Communicate now. Review by Vickie Sue
    Overall Satisfaction

    I can not begin to express how excited my wife Vickie is. As I was setting up the phone for her and manage to get in a few numbers after registering the 2400i she made me stop so she could call her daughter-in-law. What I though would be just a quick hello & good-by so I could finish loading up all her phone, I soon found that was not going to happen any time soon. She talked and talked and talked so when the phone call finally ended I show her how to enter all her contacts. She is like a kid in a candy shop. I am so happy for her, it is so amazing to see what the 2400i Caption Phone has done for her already. She has a Cochlear Implant which works absolutely wonderful. It has it's minor limitations like when communicating she read lips when you are facing her to help understand the words you project. Talking on a normal phone takes away the ability to read lips however with the 2400i Captive Phone she is able to hear and read what is being said almost in real time. I think I have created a monster ah just kidding I am really glad for her. (Posted on 2/11/2015)

  30. Love the phone! Review by Kevin
    Overall Satisfaction

    We are very happy with this phone. We always had difficulty understanding messages left on our answering machine. This phone allow us to read them. I find this phone is clearer to hear than all the other phones we tried. The close caption is a few second slow but that is not a problem. The touch screen feature is easy to read and fun to use. The menu and instructions is easy to follow. Personalize features is easy to do without referring to the manual. We highly recommend this phone. (Posted on 1/15/2015)
