If you ever have the problem of seeing the message light on your phone flashing, but you know that you have no messages, there is a quick way to make the light stop flashing.
1. Either leave yourself a voicemail, or have someone else leave you a voicemail. Remember to let the call go to voicemail if you're having someone leave you a message!
2. Log into your voicemail and press the 5 key to listen to the message. While you are listening to the message, press the 3 key to delete the message.
3. When the message has finished, press 9 and 9 again to leave your voicemail. Your message light will stop blinking.
