SMDI Voice Mail Integration
SMDI voice mail integration is available for use with Stratagy or non-Toshiba voice mail systems
and can provide more efficient voice mail integration than in-band DTMF signaling when used in
high volume applications. It requires fewer DTMF receivers and sends information quicker,
because the voice mail machine processes digital RS-232 data faster that DTMF tones.
SMDI integrates Strata DK with Stratagy and other voice mail systems, through a digital RS-232
connection on a WSIU, TSIU, PIOU, PIOUS, RSSU, or RSIU using standard central office
protocol, providing more universal compatibility with Stratagy or non-Toshiba voice mail systems.
SMDI provides all the integration features of in-band DTMF signaling, except it does not support
the equivalent of A-tone answer supervision, B-tone recall supervision, or D-tone disconnect
supervision. SMDI can be important in selling Strata with non-Toshiba voice mail systems that
customers may already have and want to keep to use with their new Strata DK system.
Advantages provided by the Strata DK and the Stratagy SMDI integration are:
Uses the ports faster and more efficiently. SMDI is a faster and more efficient integration
compared to DTMF (in-band) integration and is recommended for high-traffic installations.
Improves call coverage. Stratagy uses the call forwarding status (all calls, no answer, busy,
etc.) supplied by SMDI to provide better call coverage. Status information enables Stratagy to
perform custom applications using Stratagy RNA and Busy Chain options.
Streamlines messaging procedures. SMDI provides calling party extension numbers to
Stratagy. Users calling Stratagy do not have to enter their user ID to log onto their mailboxes.
When an internal party calls an extension that is forwarded to voice mail, SMDI applies the
calling party identification to the message. Caller ID and ANI numbers are delivered to the
voice mail machine using SMDI packets. DNIS names are not sent on SMDI packets.
Table 10 is a comparison of the feature integration provided by in-band DTMF signaling and
SMDI.
