===========================================================================

Hi all,

I have exposed the setting of silence detection mode and audio jitter 
delay in ATLSIP and SoftPhoneInterface.

Here are the methods:

DisableSilenceDetection()
- Disables silence detection. Disables CNG as well.

EnableFixedSilenceDetection( ULONG threshold )
- Enables fixed silence detection. Any sound level below the threshold 
is treated as silence (and CN is generated as a result). Don't use too 
high threshold values or you'll only hear comfort noise. Try threshold=3 
as suggested by Whit in another thread.

EnableFixedSilenceDetectionEx( ULONG threshold , ULONG signalDeadband, 
ULONG silenceDeadband  )
- An extended version of the previous method. Don't tinker with this 
unless you know what you're doing. For reference on how signalDeadband 
and silenceDeadband are used, look in OpalSilenceDetector::ReceivedPacket().

EnableAdaptiveSilenceDetection( ULONG adaptivePeriod )
- Enables an adaptive silence detection. Supposedly this enables the 
threshold to *adapt* to the current sound level every adaptivePeriod 
milliseconds. However, its silence detection doesn't seem to be very 
effective (at least in my machine). I'll look into this further to see 
what's wrong. This mode with adaptivePeriod=4800 is the default mode for 
ATLSIP.

EnableAdaptiveSilenceDetectionEx( ULONG adaptivePeriod, ULONG 
signalDeadband, ULONG silenceDeadband  )
- An extended version of the previous method. Don't tinker with this 
unless you know what you're doing. For reference on how signalDeadband 
and silenceDeadband are used, look in OpalSilenceDetector::ReceivedPacket().

SetAudioJitterDelay( ULONG minDelay, ULONG maxDelay )
- Sets audio jitter delay settings.


Regards,
Ilian
