I have a ATT 974 phone and callerid is not working on the phone? any suggestions.

I would also suggest downloading the manual. I have my answering service thru att and I call a phone # assigned to me to check messages at any time.

Same thing happened to me. Here's what I did: 1) Unplug phone. 2) Remove backup battery. 3) Wait at least 5 minutes. 4) Plug phone back in and insert battery.

Step 3 is important. I only waited about a minute the first time and the problem remained.

maybe the new battery is in stock for a long time. then it is in low power.(http://www.my-batteries.com/digital-camera-batteries/sony-np-fr1.htm)

1) reset the base . TURN OFF wait by 3 minutes. this to due the remain "effect memory" in the battery and try again.

2) must be dissapear, this happen when the are shut down of energy or similar.

3) if the problem persist Read YOUR owner manual, and go to the section troubleshooting and fix it. However you can assist ONLINE via chat or phone.

God bless you

Do you mean they are all red? Do you have all four lines being used?

Unplug everything then replug should reset the Caller ID

Check the battery on all the phones then make sure they are all programmed with different extension numbers. If the battery has been dead and you have had a power outage then it may have reset the phone to factory default extension 11.

Press PROGRAM
Press *
Press #
Enter 2 digits (11 through 22)
Press INTERCOM

This should work.

How do I change the number of rings on the phone before it goes into voice mail? If I am not beside the phone, after 2 rings it will go into voice mail and I am missing calls. The model is AT&T 974.

if your dsl is on the same line it will mess up micros for intercome system. Move dsl to another line
