The Message Waiting service provides either of the following:
A visual indicator (lamp and/or icon) and a button to access the voice mail server
A special audible dial tone that requires the user to call in to the voice mail service.
A limited subset of analog endpoints may have an indicator but not have the button to access voice mail.
The commands that are available at the voice mail server differ based on the user’s corporate policies and the desired actions, as it is uncommon for a site to use all available options. The following are the commonly present options:
Get the help menu.
Listen to an unheard message.
Listen to a message that was already heard.
Delete a message.
Save a message you heard.
Skip forward in the mailbox.
Skip backward in the mailbox.
Change settings such as the user’s password or greeting, provide out of office alerts, etc.
Log out of the mailbox.
Other options may be present, and options listed above can be omitted (for example, if the mailbox automatically saves all messages for 14 days, there is usually no need to save the message).
