Upgrade memory chip in at&t 1725 answering machine?

I'd like to upgrade the memory chip in my at&t 1725 answering machine to one
with a larger memory.  it uses a non-volatile chip, but i have not opened the unit
to see which one.  if someone has the schematics and can email them to me, or
just knows what chip it is, then i could try searching the web to see if i can find a replacement.  or, if someone knows that info already, that would be even better.   the current chip holds 24 minutes, and i'd like to up that as much as i can.  newer answering machines hold about 40 minutes, but are so far either much
harder to use, or lose all settings and messages when the power goes out.

Typically no schematics are ever available for this kind of product as nobody - even the manufacturer - expects to repair them. They are strictly throw-away. But you could open it and try to get the part number from the chip, then search out a suitable larger-capacity replacement. Problem is that almost everything now is surface-mount devices which you probably wouldn't be able to remove and replace without appropriate rework tools. Sad to say, replacement might be the best option.

I have lost my Manual for the AT&T 1725 answering Machine. Can you mail me a new manual? Send to Burnley Miles, 5325 Calvin Court, Colfax, NC. 27235


Retrevo has the manual for the AT&T 1725 here: http://www.retrevo.com/support/AT%26T-1725-manual/id/473bh046/t/2/ . You will need to enter a code to download the PDF. Adobe Reader or a similar program is required to read the file. You can print it out yourself or take it to a print shop.

I hope this helps.

On Model 1725 get message F1, how do I clear it, etc? John


CLICK HERE for your owners manual in PDF format.

F1 indicates a communication failure with the digital EEPROM (onboard memory).

Essentially you have a paperweight now.

The repair requires a replacement of the memory module, and from all accounts, that proprietary part is not sold.

I would also assert the repair to cost more than another unit (new, or used)

Thanks for using FixYa!!

Our AT&T 1725 has quit recognizing when the phone is ringing. The phone keeps own ringing instead of beign answered.


There are a couple of things to try. First is to check the cable & plug that connect the 1725 to the telephone line. Disconnect the phone line from the back of the answering machine, plug it into a known working telephone, using cell phone (or another land line) call the phone number and see if the phone rings.

If it doesn't, replace the line cord and try again.

If it does ring, check the optioning to make sure it is set for, say 2 rings.

Also, is the telephone line a regular telephone company POTS line or is it one that is being provided by a cable modem? If your phone service is being provided by a cable company, the media converter might not be putting out enough voltage for the answering machine to realize that the line is ringing.

If everything is correct, replace the answering machine.

Can not record a clear voice message


The internal microphone might be failing. If you haven't already tried….call into the answering and recording the greeting that way.

If that's been tried and doesn't work, there isn't much more that can be done as modern electronic devices are not designed to be user fixable.

You might be able to find a used 1725 or 1726 for sale on eBay.
