Messages
Short Message Service (SMS)
You can send and receive text messages using the SIP-T40P IP phone. New text messages can
be indicated both acoustically and visually. When receiving a new text message, the phone will
play a warning tone. The power indicator LED will slowly flash red, and the LCD screen will
prompt “n New Text Message(s)” (“n” indicates the number of unread text messages. e.g., 1 New
Text Message(s)) and a flashing icon .
Note
You can store text messages in your phone’s Inbox, Sentbox, Outbox or Draftbox. Each of the
boxes can store up to 100 text messages. If the number of the text messages in one box is more
than 100, the phone will directly delete the oldest text message in the box.
Note
SMS is not available on all servers. Contact your system administrator for more information.
When the phone receives a text message, the text message prompt window will pop up by
default. If you want to disable this feature, contact your system administrator for more
information.
