You can leave voice mails for someone else using the SIP-T23P/G IP phone. You can also 
listen to voice mails that are stored in a voice mailbox. When receiving a new voice mail, 
the phone will play a warning tone. The power indicator LED will slow flash red, and the 
LCD screen will prompt “n New Voice Mail(s)” (“n” indicates the number of unread voice 
messages, e.g., 4 New Voice Mail(s)) and a flashing icon          . 
 
If the voice mail pop-up message box disappears, it won't pop up again unless the user 
receives a new voice mail or the user re-registers the account that has unread voice 
mail(s). 
Note 
To leave a voice mail: 
You can leave a voice mail for someone else when he/she is busy or inconvenient to 
answer the call. Follow the voice prompt from the system server to leave a voice mail, 
and then hang up.
