Thinking about this some more, why couldn't you just split the audio from the RX and TX into two usb sound fobs.. One would handle analog though the normal app_rpt methods, and one would handle P25 though these new apps. The analog side wouldnt do anything with the P25 data when it came though, as there would be no PL on it to activate the regular RX app. Seems like it might work.

I see a rx-to-asterisk app here, but not a corresponding asterisk-to-tx app. I saw a repeater app but didnt appear to support asterisk. Am I missing something or does it not exist? Thanks!
