Where do I replace the ATT ML17929 Directory Card?

Had a heck of a time trying to figure out what you were talking about.  I finally found it in the manual and they do call it a directory card they're actually call desi labels or desi strips (for designation).  So when I put in desi label in google I get them but don't show any for your specific model of phone.  I find them for 4 line phones here I don't know if you could cut them down and make them work for your 2 line phone or not.  You might call Desi and see if they can match them, I've used them for business systems.  Now I just need to figure out why you'd have to change them everyday.

Also, the reason why I cannot cut them down is because they don't have a "LOWER" button, which I need to lower the speed dial.

You can always cut that line out, or cut a small square out for the button. You know what it's for does it really need to say "lower"?

These are the choices I see you have.

1. Try the desi's for the 4 button sets. It's if the buttons line up that's important.

2. Call Desi and see if they have something that will work

3. Call the number in the front of the manual. 

4. Make you own desi's from a spread sheet, least desirable in my opinion

Personally I think number 1 is the best choice if the buttons line up.   You can always keep searching for the right one if none of the above work.

I need to replace them daily (usually 2-4 days) because our employee directories would be changed slightly or more extensions being added.

Also, the reason why I cannot cut them down is because they don't have a "LOWER" button, which I need to lower the speed dial. Anyway, that was a great help.

I called them, and they don't have one for the ML17929 model.

I found out you can only buy these over the phone, thanks for the help!

We're glad to hear you were able to get it figured out!

Thank you for being the best part of AT&T!
