The number to reach a voicemail box to leave a voicemail is the same as the phone number attached to it. When the person does not answer, the voicemail box greeting begins, and the caller records a message after the beep.
The number to get into a voicemail box and listen to messages is a secret personal identification number (PIN) that the voicemail box owner chooses when the account is set up. The number a voicemail box owner calls to retrieve messages from a different phone is the number that is attached to his or her voicemail box. The user should tap the pound key (#) when the greeting starts and put in the PIN to hear the messages.
