The InitializeInBandDtmfDecoder API procedure can be called to initialize in-band DTMF detection
for a phone line. Once in-band DTMF detection is initialized and enabled, the media engine will send
the SipDtmfDigitEvent events to the application whenever ON or OFF DTMF digit transitions are detected.
See the
SetInBandDtmfDecoderEnableState(Int32, Boolean) API procedure for information regarding enabling
in-band DTMF detection for the phone line.
 Note: |
You should not use this form of this API porocedure unless your application requires custom DTMF decoder tuning.
Please see the InitializeInBandDtmfDecoder(Int32) API procedure for initializing an in-band DTMF
decoder with default behavior.
If your application requires specific DTMF decoder tuning, please contact LanScape support for further details
and pricing information.
