I have a analog phone that I can't get the message waiting light to go off of. I have called and left message then erased it and the light still is on. Any ideas ??

To answer a Message Waiting:
When you have a message, your MW LED flashes fast for keysets.
1. At a keyset, press idle CALL key and dial *0.
OR
Press Message Waiting key (PGM 15-07 or SC 851: 38).
OR
At single line terminals, lift the handset and dial *0.
If the called extension doesn’t answer, dial 0 or press your Message Waiting key to
automatically leave them a message.
Normally, your MW LED goes out. If it continues to flash, you have new messages in your
“Voice Mail” mailbox or a new “General Message”. Go to “To check your messages” below.
To cancel all your Messages Waiting:
This includes messages you have left for other extensions and messages other extension
have left for you.
1. At keyset, press idle CALL key.
OR
At single line terminal, lift handset.
2. Dial 873.
3. Hang up.

Look at message waiting. Should be 873.
