Description:At high-level protocols (like PRI) there is some knowelege about current in-band tone from signalling messages (ALERTING means there is ringing, etc.). Also, PRI have ANSWER signal which informs remote party is answered and voice you will listen is remote person's voice/TAD, not voice information message from network/etc.

This patch is intended to provide ability to disable some sort of call progress messages to not disturb call processing with faked messages when current conditions is well-known.


Disclaimer is on file.

This patch just DSP part, use the features this patch provides at channel code.

How about leaving them all positive and just defining DSP_FEATURE_CALL_PROGRESS to be the bitwise or of all the call progress features?
