JVoIP - GStreamer integration  
	Implement any kind of VoIP audio streaming
	JVoIP: https://www.mizu-voip.com/Software/SIPSDK/JavaSIPSDK.aspx
	GStreamer: https://gstreamer.freedesktop.org/
	
Workflow:	
	1. Launch GStreamer to listen on a specific port
	2. Use the JVoIP Media notification events to capture audio packets from SIP and forward it to GStreamer listener port
	3. Generate audio stream from GStreamer and send it to JVoIP with the API_StreamSoundBuff function
	
	
GStreamer launch command line examples: 
	gst-launch-1.0 -q tcpserversrc host=127.0.0.1 port=65432 ! rawaudioparse num-channels=1 pcm-format=s16le sample-rate=16000 ! audioconvert ! audioresample ! autoaudiosink

	gst-launch-1.0 -q audiotestsrc freq=440 wave=sine ! audio/x-raw, pcm-format=s16le, rate=8000,channels=1 ! tcpserversink host=127.0.0.1 port=65433

	gst-launch-1.0 -q pulsesrc ! audioconvert ! audioresample ! audio/x-raw, pcm-format=s16le, rate=16000, channels=1 ! tcpserversink host=127.0.0.1 port=65433

	gst-launch-1.0.exe -e audiotestsrc wave=sine freq=440 num-buffers=800 ! audio/x-raw, format=S16LE, channels=1, rate=8000 ! wavenc ! filesink location=sine_wave.wav

	C:\apps\gstreamer\bin\gst-launch-1.0.exe -q audiotestsrc freq=440 wave=sine ! audio/x-raw, pcm-format=s16le, rate=8000,channels=1 ! filesink location="test.wav"

	gst-launch-1.0 -v alsasrc ! wavenc ! 

	C:\gstreamer\1.0\msvc_x86_64\bin\gst-launch-1.0.exe -q audiotestsrc freq=440 wave=sine ! audio/x-raw, pcm-format=s16le, rate=8000,channels=1 ! tcpserversink host=127.0.0.1 port=65433
