Message light on top of phone blinking but no new messages

Message Waiting Indicator Your phone's message waiting indicator is either a light or special tone that alerts you when you have voice mail.

Occasionally, the message waiting indicator may be out of sync with your mailbox. In that case, the indicator light or tone is ON but there are no messages waiting, or the indicator light or tone is OFF when there are new messages waiting.

To get the message indicator back in sync

1. Save or delete all new messages
2. Hang up.
3. If the message indicator does not go out or stop within a few minutes, there may be a problem, and you should contact Verizon.
4. If the message indicator does go out or stop, call your own number and leave a message
5. Hang up and wait
6. If the indicator light or tone does not come on within a few minutes, there may be a problem, and you should contact the vender.

That means there is a message. If it's blinking at the top of the phone it means that you need to check your messages. After you check them the blinking will stop.

The flashing message light may be telling you there is voice mail on your telephone line. If you have "home voice mail" or whatever your phone service provider calls their service, you're told of new message by a stutter dialtone. That is, when you pick up your phone to make a call, you hear two or three brief bursts of dialtone before it goes steady. Many new phone systems start flashing their message light when there are waiting messages so that you'll know about them if you don't pick up your phone. Follow whatever procedure your provider gives (usually you call a local access number) to pick up your messages, and that light should quit blinking.

messege again after the announcement "To delete all messages, press delete

When you try to delete all messages without first listening to your new messages,
you hear several short beeps followed by an announcement "Please playback all
messages." This protects you from accidentally erasing messages you have not yet
reviewed.
Important:
When you press delete messege, you are permanently deleting the message. Once
deleted, the message cannot be replayed or retrieved.
