Setting The Voice Mail Integration Digits
Description:
You can choose the DTMF digits that the DXP Plus sends to a voice mail system. A voice mail
system uses these DTMF digits to determine system and station status so that it can properly
process a call. You must be versed in your voice mail’s requirements before you can assign
DTMF integration digits in the DXP Plus. The system defaults the voice mail parameters to
match the Comdial voice mail system. Certain applications in countries with dialing plans
different than the United States may require different integration digits. The default digits are
shown in the following list and discussed below:
Follow Extension ID = 2 Intercom/Answer Confirmation = 1
Busy = 2
Do Not Disturb = 3
Incoming Intercom Answer = 9 Disconnect = A
Follow Extension ID - When the voice mail system receives a forwarded call from a ring
no-answer (RNA) or busy station, the DXP Plus sends to the voice mail system the extension
number of the forwarded call followed by this DTMF digit (n). The DXP Plus sends this digit
within 500 ms of the time the voice mail system answers the call. For example, if extension 101
is forwarded to voice mail and voice mail answers a forward RNA or busy forwarded call, the
DXF’ Plus sends 1Oln to the voice mail system within 500 ms of the answer time.
Intercom/Answer Confirmation - The DXP Pkus sends this DTMF digit to the voice mail
system to confirm that an intercom path (without dial tone) is available for the voice mail
system’s call transfer or dialing use. The DXP Plus sends this digit within 500 ms of the time it
detects the voice mail system’s off-hook or hookflash condition. The DXP Plus ah
immediately sends this digit to the voice mail system when a station answers a voice mail
transferred call. This action can alert the voice mail system to disconnect and leave the parties
connected.
Busy - If the voice mail system transfers a call to a station that is busy on a call, the DXP Plus
sends this DTh4F digit to the voice system. When the voice mail system receives this digit, it
can abandon the transfer, reconnect to the call, and offer the caller whatever options the the
voice mai system has available in its programming. If the DXP Plus auto attendant transfer on
busy feature is active, the DXP Plus will not send the DTh4F digit to the voice mail system thus
allowing the system to transfer a second call to the station.
DND - If the voice mail system transfers a call to a station that is in the do not disturb (DND)
mode, the DXP Plus sends this DTh4F digit to the voice system. Receiving this digit allows the
voice mail system to distinguish between a busy and a DND condition and offer the caller the
appropriate choices.
Incoming Intercom Answer - The DXP Plus sends this DTMF digit to the voice mail system
when a station user makes an intercom call to the voice mail system. This action allows the
voice mail system to distinguish between internal and external calls and offer the caller
appropriate prompts and dialing options.
Disconnect - When an outside line or intercom party hangs up, the DXP Plus sends this DTMF
digit to the voice mail system to command an immediate disconnect. For outside calls, the
central office (CO) must provide disconnect supervision to the DXP Pkus and you must program
the DXP Plus line for abandon hold release and disconnect supervision (see Section 8. I for
details). At default, the DXP Plus sends the DTMF tone for the A character as the disconnect
digit. Since a caller cannot dial an A from a telephone. This feature eliminates callers from
causing an accidental disconnect by dialing this digit on their telephone’s dial pad.
