What does option #1 “To Record Messages” really do?
This option is often mistaken as the one to use to record a greeting. What it really does is “Send” a message through the voicemail system to one or more people without actually ringing their phone. This feature can be useful in several situations. For example you can use it late at night when you don’t want to wake someone up but still want to leave a voicemail message. You can also send a message to yourself as a reminder of an appointment.
