If the red light at the top of your phone is blinking it can mean three things:
- You have a voicemail, in which case you need to press VM at the top of your phone and listen to each message
- You have a message waiting request. In this case you should see MW on the display of your phone. To clear the MW, press speaker and dial 771 then hang up.
- You have another extension “camped” on your extension, to clear the camp press speaker, dial 770 and hang up.
