MF tone detection is now supported. Previously, only MF tone generation was supported.
• Increased granularity for DX_MAXSIL and DX_MAXNOSIL termination conditions
(DV_TPT structure)
The range of valid values for DX_MAXSIL and DX_MAXNOSIL is now 10 ms to 250
seconds (1 to 25000 in 10 ms units). There are no further restrictions within this range.
Previous range of time was 1 second to 30 seconds, with step values.

This feature enables streaming to a network interface in real time which is essential in
applications such as text-to-speech and IP gateways. Several new functions have been added to
the Voice library.

The dx_SetRecordNotifyBeepTone( ) function has been added to the Voice library.
