AT&TCL82507 DECT 6.0 5-Handset Cordless Phone for Home with Answering Machine, Call Blocking, Caller ID Announcer, Intercom and Long Range, Silver

We were tired of receiving all the calls from UNAVAILABLE and this product seemed to promise a solution for that. Our previous AT&T answering machine was simple and easy to use, but we were being bombarded with UNAVAILABLE calls and looking for a better solution.We used to have a "Princess" phone in the bedroom that would work on AT&T home office battery power when electrical power outages were occurring in our area but, since our telephone service is now via fiber, that emergency solution was no longer viable... so we replaced the Princess by adding another handset, bringing us to a total of five.The new system solution comes with a huge cost, however, in that some callers, both live and recorded, end up being drowned out by a high-pitched, very loud oscillation that makes it impossible to hear the caller's message.At first we though that we were being called by a fax machine -- it was that kind of signalling sound -- but when one listens closely they can tell that the voice on the other end is being swamped by this annoying fixed frequency oscillation being modulated by the caller's voice.When the caller is a human, I simply call them back from their saved ID in the log... and there isn't the annoying feedback problem. Trying to call back a recorded message machine, like one delivering a message from the doctor's office to report a scheduling problem... well, there's no calling back possible in that scenario.I've submitted the problem to AT&T and have been promised a reply within 48 hours.== Update ==AT&T Customer Sales did reply within 24 hours with an email asking me to call their service center and apply a sequence of prompt responses that led me to "Jason" for support.Jason and I worked through several possibilities including: 1. removing batteries from the handsets for a minute or two then reinstalling; 2. moving the base station from the kitchen to another wall phone outlet in my office; 3. moving the base station to connect directly with the telephone output jack of the Internet modem.After all of these maneuvers, Jason opined that the problem might be not with the cordless phone system but rather with the incoming fiber, modem etc. We were out of other tests to try, so we opted to investigate that possibility.That led to another call to AT&T, to the service number on our monthly local bill, where I eventually dealt with "Germaine".For his part of this drama, Germaine performed an "account reset" and consulted with the "back office" two or three times. Somewhere in all of the calling I managed to connect with an AT&T help line that exhibited the precise high frequency modulation problem that we were investigating... and I recorded the sound on my iPhone.I played that sound for Germaine and also related the exact time and caller information (from the call log) that the original problem was first recognized. Germaine remotely investigated the recent history of our Internet modem and could not find a correlation in the log with the time of the problem... in fact, the modem log showed no problems from before the initial "problem" call to the current time, including the problem just recorded on the iPhone.At the end of our 45-minute or so session, Germaine concluded that we don't have enough information to isolate and solve this problem. He recommended that I keep a log of the time, date and telephone number of further occurrences of the problem, to be used as additional data the next time I call the service number.===========My personal opinion is that there is a system setting in the base station or the handsets relating to echo cancellation or automatic audio gain control or frequency roll-off or audio squelch that isn't configured properly. I see nothing about any of those things in the 170+ page user manual... but I do remember seeing a handset screen briefly displaying a message related to audio settings when I inadvertently pressed some odd combination of buttons when picking up a dropped handset.I like many of the other features of this product; it has more capabilities than I need and is a little complicated to use compared to our old model -- but at least with the older system we could always hear the callers, live or recorded.====21 September 2023 Update?Not really an update; nothing has been fixed. Still getting high pitched loud modulation on about 10% of the incoming calls. If we're home and hear the noise we can sometimes pick up a receiver and tell the caller to try calling back... and usually the call works on the second try. Messages that are obliterated by the high frequency noise and end up on the recorded messages... well, they're just toast.Very disappointed that this fault cannot be addressed and corrected.

This is a clean new set with an extra handset for an old AT&T system I've had for too many years. I have yet to discover a one button intercom access and that is very inconvenient. Programming is tedious but once you get in the swing of it pushing which button which way it is doable. As I have somehow lost any book that came with this already, I wish there was a way to transfer the old phone book on the old phone set to the new phone set without going number by number. New feature on this is blocking, which will be used regularly for sales pitch phone calls. This is a good setup for the price it's an excellent setup. I hope I do discover the one button intercom feature

bought one base phone for my desk, and added the 4 more hand sets one in kitchen, 1 in living room, 1 in 2 different bedrooms, when a call comes in I can hear it in master bed room then on second ring all the phones ring. my Hubby is sleeping between 4 a.m. and 12:p.m. the bedroom phone rings one ring before the rest and in the bedroom and wakes him up before I can get to one of the other phones. Is there a fix for this? I have tried turning the master bedroom ringer off but then when I am in the master bedroom I can not hear the calls that come in.

I really like the phones they have everything I need including blocking numbers and if someone calls more then once it tells you

A+
