   • Using GStreamer  

RECEIVE GSTREAMER COMMANDS FOR HOST:
1. gst-launch-1.0 udpsrc caps="application/x-rtp,clock-rate=(int)48000,payload=(int)96,channels=1" port=5001 ! rtpjitterbuffer latency=15 ! queue ! rtpopusdepay ! opusdec ! audioconvert ! audioresample quality=10 ! jackaudiosink client-name=RECEIVE1 buffer-time=30000
2. gst-launch-1.0 udpsrc caps="application/x-rtp,clock-rate=(int)48000,payload=(int)96,channels=1" port=5002 ! rtpjitterbuffer latency=15 ! queue ! rtpopusdepay ! opusdec ! audioconvert ! audioresample quality=10 ! jackaudiosink client-name=RECEIVE2 buffer-time=30000
3. gst-launch-1.0 udpsrc caps="application/x-rtp,clock-rate=(int)48000,payload=(int)96,channels=1" port=5003 ! rtpjitterbuffer latency=15 ! queue ! rtpopusdepay ! opusdec ! audioconvert ! audioresample quality=10 ! jackaudiosink client-name=RECEIVE3 buffer-time=30000
TRANSMIT GSTREAMER COMMANDS FOR HOST:
1. gst-launch-1.0 jackaudiosrc client-name=TRANSMIT1 provide-clock=true do-timestamp=true ! audio/x-raw,channels=2 ! audiorate ! audioconvert ! audioresample quality=10 ! opusenc bitrate=128000 frame-size=5 ! rtpopuspay ! udpsink host=(ipADDRESSofOP1) port=5004
2. gst-launch-1.0 jackaudiosrc client-name=TRANSMIT2 provide-clock=true do-timestamp=true ! audio/x-raw,channels=2 ! audiorate ! audioconvert ! audioresample quality=10 ! opusenc bitrate=128000 frame-size=5 ! rtpopuspay ! udpsink host=(ipADDRESSofOP2) port=5005
3. gst-launch-1.0 jackaudiosrc client-name=TRANSMIT3 provide-clock=true do-timestamp=true ! audio/x-raw,channels=2 ! audiorate ! audioconvert ! audioresample quality=10 ! opusenc bitrate=128000 frame-size=5 ! rtpopuspay ! udpsink host=(ipADDRESSofOP3) port=5006

remote OPs do the similar as above...but only need one RECEIVE Gstreamer and one TRANSMIT Gstreamer

for their TRANSMIT Gstreamer command line - they use the HOST ip address and HOST unique assigned port...

port forwarding will be used for both HOST and REMOTE OPs
to port forward in their routers, their assigned GSTREAMER RECEIVE ports to the computer they are using...
