4.6.5. Setting the Message Waiting Indicator
The Dialogic® PBX Integration Board can set the Message Waiting Indicator
(on or off) on another extension using the dx_dial( ) function and the
appropriate dial string. Refer to the Dialogic® PBX Integration Software
Reference for more information about dialing programmable keys.
NOTE: Message Waiting can also be set using the dx_dial( ) function and
the appropriate dial string to press the Feature Key assigned to send
messages. However, you can use the dx_dial( ) function as described
so that your application will maintain functionality across different
manufacturers’ switches.
MWI On
A technique to turn on the MWI in this switch, using dx_dial( ) with the dial
string, is to:
• Call the dx_dial( ) function.
The dial string is <ESCO>,<extension>,<ESCO>.
NOTE: <ESCO> means the Escape character followed by O.
