A message button or message reply feature code has been used to call the VM/AA
port.
7. PROGRESS TONE ID
These are the DTMF codes that
progress tones. For example, when a VM/AA port goes off hook to originate or
transfer a call, instead of hearing normal dial tone, it will hear DTMF "BA".
Progress tones can greatly increase the efficiency of a VM/AA system because it is
easier and quicker to detect DTMF than a busy, ringback or DND tone.
Progress tones can identify any of the following.
TONES VALUE
0. DIAL TONE
1. BUSY TONE
2. RNGBACK TONE
3. DND NO MORE
4. HDSET ANSWER
5. SPKER ANSWER
GENERAL RULES
1. 201 is talking to a trunk and presses TRANSFER plus the station number, but the
station is forwarded to VM/AA and VM/AA answers. When this happens, if 201
presses TRANSFER again to return to the trunk, the VM/AA port is not on hold. It is
disconnected.
2. A VM/AA port leaves a message indication for a station. When the station returns
the message, any available port in the VM/AA group should ring, not only the one
that left the message.
3. A VM/AA port leaves a message for a station. When the station returns the
message, the MESSAGE LED is not automatically turned off. If a VM/AA system
turns on the MESSAGE LED, the VM/AA system must turn it off.
4. If DTMF call progress tones are not enabled, the system sends regular call
progress tones (see Item #3).
5. When a VM/AA port calls a station that is in the AUTO ANSWER or VOICE
ANNOUNCE mode, the keyset will be forced to ring.
6. All calls to a VM/AA port or group will ring with C.O. Line ringing cadence, not
intercom ring cadence.
EXAMPLES OF VM/AA OPERATION (IN-BAND DTMF DIGIT STRING)
In the following example, all call and type data is turned on unless otherwise
stated.
X is the separator digit, all-default values are used in these examples and [ ]
means an item is not used.
A DIL 701 calls a VM/AA port or group:
[*] + [701] + [ ] + [ ]
In the above example, if C.O. information is not used:
[ ] + [ ] + [ ] + [ ] (Nothing is used)
DIL 701 calls a call-forwarded station (205):
[#] + [205] + [X] + [701]
In the above example, if forward information is not used:
are sent to the VM/AA port in place of regular
