Voice Mail Integration Digits

Installers can choose the DTMF digits that the FX II 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. Installers must be versed in the voice mail’s requirements before they can assign DTMF

integration digits in the FX II. 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 = 2 Disconnect = 2

Follow Extension ID—When the voice mail system receives a forwarded call from a ring no-answer

(RNA) or busy station, the FX II sends to the voice mail system the extension number of the

forwarded call followed by this DTMF digit (n). The FX II 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 FX II sends 101n to the voice mail

system within 500 ms of the answer time.

Intercom/Answer Confirmation

—The FX II 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 FX II sends this digit within 500 ms of the time it detects the voice mail system’s

off-hook or hookflash condition. The FX II 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 FX II 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 voice mail system has

available in its programming. If the FX II auto attendant transfer on busy feature is active, the FX II

will not send the DTMF 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 FX II sends this DTMF 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 FX II 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 FX II 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 FX II and the installer must program the FX II line

for abandon hold release and disconnect supervision. At default, the FX II sends the DTMF tone for
