4. Define the following parameters:
Maximum Digits in In-Band DTMF Strings
The number of digits in the In-Band
DTMF Strings will be different depending on the PBX models. This parameter will
limit the maximum number of digits that can be received by IM1200. Digits exceeding
this number will be ignored.
Maximum Time to Wait For First Digit This parameter sets the maximum time to
wait for the first digit of the In-Band DTMF String sent by the PBX to arrive when a
call is answered. If no digit is received at the end of this time, the call will be taken to
the channel’s main AA menu greeting.
Maximum Time Between Digits This parameter defines the timeout between digits
in the In-Band DTMF String sent by the PBX. If no further digit is received after this
timeout, IM1200 will stop the waiting and use the string received thus far to determine
the status of the extension.
To Define the In-Band DTMF Protocol
5. Choose
System Parameters > In-Band DTMF Protocol.
6. Click Edit tab, an In-Band Protocol Details dialog box appears.
7. Select the row of the string you want to edit.
