When I press memory buttons on one particular telephone in our office they all dial reception. How do I fix this?

These errors are usually related to interference, static, or noise on your phone line. Here are some steps to troubleshoot and resolve the issue:

Check for a dial tone:
1. Press the Hook button on your Brother Intellifax 2820 and listen for a dial tone.
If there is no dial tone, press Hook again and proceed to step 2.
If there is a dial tone, press Hook again and move to step 4.

2. Verify telephone cord/line connection:
Ensure that your telephone cord/line is correctly connected to the port labeled LINE on your machine (located on the lower left side).
If the cord is already in the LINE port, proceed to step 3.
If it's connected to EXT, remove it from there and connect it to the LINE port.
Press Hook and check for a dial tone.
If still no dial tone, proceed to step 3.
If there's a dial tone now, move to step 4.

3. Test with a known working telephone:
Disconnect the telephone cord/line from the LINE port on your machine.
Connect it to a known working telephone and test for a dial tone.
If there's no dial tone, the issue is related to the telephone line or wall jack. Contact your telephone service provider.
If there's a dial tone, reconnect the cord/line to the LINE port on your machine.
Press Hook and check for a dial tone.
If still no dial tone, consider warranty and service options.
If there's a dial tone, proceed to step 4.

4. Remove splitters or other devices:
Check if you have any splitters, commshare devices, credit card machines, or power strips connected to your machine or the telephone wall jack.
If yes, remove them for testing purposes.
After removing any devices, continue to step 5.

5. Adjust Compatibility settings:
Press Menu/Set.
Navigate to Miscellaneous > Compatibility.
Choose Basic (for VoIP).
Press Menu/Set and then Stop/Exit.

6. Send a fax:
Insert the document face down in the Automatic Document Feeder (ADF).
Adjust paper guides to fit the width of your document.
Enter the fax number using the dial pad.
Press Fax Start.

Remember that testing the Brother machine on a different, known-working telephone line can help determine if the issue is related to the machine or the telephone line. If the problem persists, consider contacting Brother Customer Service for further assistance.

If you feel the need to seek another machine, assess the features you need and your budget. Here are possibilities: here are some reputable brands and their models to consider:

I was unable to locate a user manual for that particular device, however the basic instructions for programming speed dial functions are normally very similar between most phones.


Generally there are ONE TOUCH Speed Dial buttons labelled something like M1, M2, and M3 on the dial pad somewhere.


There should also be another button labelled PROG or STORE on the keypad as well.


Normally to program a number into a ONE TOUCH speed dial memory location you carry out the following procedure:


Lift the handset.


Then press the PROG (or STORE) button.


Now just use the number keypad to dial the full telephone number that you want to store in a Speed Dial location.


Once the full telephone number is dialed, then push the M1 button to store that phone number in the M1 One Touch Speed Dial location.


The phone may or may not show some kind of confirmation that the M1 location was just programmed, then just hang up the handset.


Now when you lift the handset and press the M1 button, the phone should automatically dial the phone number you programmed into it.


Now just repeat the same process for the M2 and M3 One Touch Speed Dial buttons with other phone numbers if necessary.


To change one of the Speed Dial numbers, just carry out the normal programming procedure for that location using the new phone number and the old number will simply be overwritten.


I truly hope that was helpful to you.
Good luck and take care.

Given that consumer telephones are inexpensive, the cost of repairing the speaker phone on the 960 (assuming you still have it) is probably not worth it.

Going off of my memory....to program a speed dial you would first press "Program", enter the telephone number you want stored and then press the one of the memory buttons to save the number to. If the number is to be saved on a lower memory position press "Lower" before you press the memory button.

AT&T's telephone product website has a section where user manuals for many AT&T and Lucent branded telephones.

The 960 is no longer listed, but the many of the basic functions are similar to the 922.
