VOICEMAIL（MESSAGE WAITING INDICATION）
If the blue Message Waiting Indication (MWI) LED icon is flickering in the HOME button, a new voice mail
has been received and is waiting to be retrieved. To retrieve the voice mail, activate dial pad first. Then

“Voicemail ID” configuration under “Accounts” in the web configuration interface.
