Voice mail indicator light is always on

I have 6 of these phones. No problem for a year or so, then one phone got the message light stuck on. Tried some online suggestions without success. Powering down etc. failed to fix it so I stuck a piece of tape over the led.

A couple of weeks ago line 2 failed (externally) and ATT sent a tech out who repaired it and also cleaned up the line. When the line came back, all 6 phones had the message light stuck on!

Talked with the tech here and with the ATT support and nothing worked. Eventually the tech here left as it was not a line fault - but he said he would leave the problem open.

That evening a young ATT guy called. He tried a number of different settings and changes - he was really determined! He called Kentucky and Minnesota and part of the advice was "give up and don't call the customer back"!

Finally he found a configuration option in the central office switch (exchange) for the line called CWMI (Call Waiting Message Indicator). Apparently this option was originally active but was changed when the local trunk was upgraded to fibre over the last year or so.

Once he enabled this option (we have call waiting and caller ID on call waiting on this line), the message lights on all the phones turned off and have worked normally since (10 days), including the one that was "broken" for over a year!

I really credit the tech with persistance on the issue.

Hope this helps someone else out there.

I recently changed my number and when I did, I received the same problem. It appears that AT&T didn't add the Message Indicator Light service to my new number. Once they did, the message light works!

Try calling your phone service provider and asking if they have a Message Indicator Light function.
