Line 4 on my 974 AT&T Phone is flashing when not in use?

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

All of the lines are steady red, which means the line is in use by another set. However, no other phone is using those lines. Can you shed some light on what I need to do.

You need to find where your phone line has a problem. This could be a sign of a wiring problem inside or outside or a problem with the phone itself. First try another phone at the current jack (I prefer to use an old corded phone with a different phone wire). Since this is a 4-line phone, you will need to check each line separately. Check for dial tone. If the test phone works, try the second wire with the ATT-974. If it still doesn't work, replace the phone. Modern phones aren't meant to be user fixable. If neither phone works, continue below.

Next try both phones at a different jack. If the phones both work and the jack is for the same line as one of the lines to the first jack, then you probably have a wiring problem at the jack or leading to the jack for all of the lines. You can open the faceplate and check for loose wires. If it is the wires to the jacks, you may want a professional to deal with the issue.

If you get the in use message at other jacks on both phones, find where the telephone service comes in. If you are lucky, that will terminate in RJ-11 jacks. Then open the service box and use your test phone there. If the problem occurs at the service box, call your phone company. They should fix it for you. If the dial tone is normal, it's an inside wiring problem. The phone company will fix it for a fee. (If the service uses a non-RJ11 jack, you should have the phone company do this test.)

I hope this helps.

(who has gotten a line in use error when mice chew on the wires or a crew dug too deep near the underground wires. Sometimes we'll hear a fast busy signal when the handset is picked up with the problem. Although with 2 line service, only the digging humans usually cause a problem with both lines. Animals only damage on line at a time outside.)

Phone lines are not rolling over to the other lines, also when retrieving a call from line 2 ..I can here the person on hold but not able to speak with them.

The rollover trouble is a service provider issue, you need to call your service provider to report it. The second trouble could be related , I would report it to the service provider also. Once the rollover rissue is fixed, test for the second trouble again.

I have a 974, 945, and 955 phones in a 2-line office. I am getting a squeal on the intercom when I call just one phone. It works fine between other phones. It worked for 2 years and then the squeal showed...

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.
