ioctl(ixj, PHONE_DTMF_OOB, int oob)
Return Value
None.
Parameters
If the parameter is TRUE then the DTMF will only be sent Out Of Band. If the parameter is FALSE the DTMF will be sent both Out Of Band and in the audio channel if record is active.
Remarks
Causes the record channel to be muted during DTMF detection. This prevents the DTMF tones from being sent in the audio channel to a remote system, so they can be sent Out Of Band.
