Object
column
r/w
Unsigned32
Defines the minimum duration a DTMF must last to be detected. A DTMF
whose duration is less than the configured value is not detected.
A higher value may help prevent false DTMF detection. However,
increasing the minimum duration can impact jitter if
voiceIfDtmfTransport is configured for out-of-band DTMF.
This value is expressed in milliseconds.
This variable's semantics are different depending on protocol and/or
hardware platforms. Please refer to the documentation
