How do I send a voicemail message internally (extension to extension) with the SBX-IP 320 system?

On your phone:

• Press the Callback button to access your voice mail.
• Press 3 (Send option) to send a message to another mailbox.
• Listen to the prompt to start recording your message after the tone. (Your message must be 5 seconds or longer)
• Press # to end your recording.
• Now the system will ask you for the mailbox you want to send your message to***
• Enter the three digit mailbox number (i.e. 101).
• Your message has now been sent to the mailbox. You may now hang up.***If your message is shorter than 5 seconds you will not be prompted for the mailbox.
  ***YOUR MESSAGE MUST BE LONGER THAN 5 SECONDS.
