RTSP Talk back function through BICommand

[SteveSteveSteve]

Hi,

I have RTSP talk back (two way audio) working through Blue Iris, but it requires me to manually press the microphone button.

I would like to play sound files through my camera using the talk back feature. Is it possible to either:

1) Play sound files through the camera speakers using BICommand?
2) If not, then just open/close the audio channel (i.e., same function as pressing/unpressing the microphone button in BI), through BICommand?

Either will work...

Thanks,
Steve
