Voice Mail/Auto Attendant Integration
(In-Band / SMDI )
This section focuses mainly on in-band integration. Systems may alternatively accommo-
date Bellcore standard SMDI—available by setting in MMC 210 (SMDI VMS SET option).
Because of the increased popularity of voice mail and auto attendant use, all DCS systems
include many programmable options to address this demand. The degree of integration
that can be achieved depends on the abilities of the voice mail/auto attendant (VM/AA) sys-
tem as well as the telephone system.
The following describes the capabilities provided by systems for voice mail via in-band inte-
gration.
Hardware Provisions
• The VM/AA system must be connected to single line circuits on any SLI card.
• Each port is equipped with a dedicated DTMF receiver for detecting DTMF signalling
from the VM/AA.
• These ports also provide an instant break in loop current when the calling party
hangs up. This is called a disconnect signal.
Software Provisions
• Screened Or Unscreened Transfer
There are no special codes needed to transfer a call. Simply hookflash, receive
transfer dial tone and dial the destination.
• Direct In Lines
Any C.O. call can be assigned to ring at an individual station or a station hunt group
assigned to the VM/AA.
• Calls or Recalls to the Operator
Dialling 0 will always result in a ringback signal. If the operator is busy, the call con-
tinues to ring in queue to the operator.
• Message Waiting
A VM/AA port can leave a message at any station or group of stations. The message
waiting indication can be set or cancelled at any station or station group with or with-
out the stations ringing.
