Something I am looking for that is related but not quite the same as this is I have a remote General Coverage radio receiver and it has a full control VB.NET app that runs on an XP VM (Windows has to be good for something :-) at the remote location. That VB.NET app talks to the radio by way of a COM port on the host. I can either RDP into the XP VM or the VB.NET can be remote controlled by another copy using something like DCOM (I assume) (I am no M$ programmer). For remote audio streaming, I have connected it to a linux box sound card's Line In and using ICECAST/Darkice, I can easily stream it to wherever using MP3.
But, I also do a lot of VOIP with Asterisk/Trixbox and I know some sort of real time audio using RTP/RSTP much be possible. But, I am not sure what is the best way to accomplish this with a Linux server at the remote end. I have to have Linux in the mix somewhere here too! :-) I have toyed some with Apple's Darwin Streaming Server (DSS) which is supposed to feed with RTSP/RTP. The reason I need real time audio is that remotely controlling the VFO of a radio is a real pisser if you have to wait 5-10 secs for the signal's audio to reach you. It would be like tuning across the FM dial with a 10 second lag. Believe me, it is maddening. I have to change freq and and wait, change and wait, and so on. I know some people stream audio from scanners, etc, using things like Teamspeak, but I want to have the audio served/managed locally. I know with ham radio things like IRLP (?) and Echolink and Hamsphere using some form of RTP. And, VOIP too. Ideally what I need is a real time audio client/server soluton with the server on linux and the clients on windows or linux.
