Setting The Voice Mail Integration Digits
You can choose the DTMF digits that the DXP 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. 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
sends to the voice mail system the extension number of the forwarded
call followed by this DTMF digit (n). The DXP 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 DXP sends 101n
to the voice mail system within 500 ms of the answer time.
Intercom/Answer Confirmation - The DXP 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 sends this digit within 500 ms of the time it detects the
voice mail system’s off-hook or hookflash condition. The DXP also
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 sends this DTMF 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 mail system has available in its programming. If the DXP’s
auto-attendant-transfer-on-busy feature is active, the DXP will not
send the DTMF digit to the voice mail system, therefore allowing the
system to transfer a second call to the station.
