Well I actually had to create an extension that opens the other end of the loopback device I am piping the audio into. I made an extension and it can be called up. I’m basically using alsa as a end point. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I guess for now it could be used to play noaa weather or any other frequency you want to sit it on. Rtl_fm has some cool features like you can add a few frequencies and rtl_fm will scan through them while its running. There could be an issue with squelch though, if there is a lot of noise it could keep the node keyed up and the squelch feature in the rtl_fm is quirky, it doesn’t cut the noise floor out weird. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Now that I have confirmed a working setup that audio can come into ASL from the SDR and learned a little more about this beast Asterisk I can figure out next steps. It wont be this way lol, we would need a Alsa type driver we can call from rtp.conf. Mike KB8JNM mentioned look into usrp. From some brief looks at it and I found that you can split the rxchannel and txchannel in rtp.conf. so what if I txchannel = UsbRadio/usb46596 and rxchannel = <span style='color:#24292E;background:white'>USRP/127.0.0.1:34001:32001. I don’t know much about usrp so I will have to see how I can pipe the audio of the SDR into that channel.
