[App_rpt-users] DTMF Commands not processed?

Should i be able to see dtmf digits received by a URI device in the CLI?
I'm having trouble getting app_rpt to respond to commands over the air?

I only see carrier detect related messages with asterisk -rvvvvvvvvv when i
key a radio.

[Oct  6 13:35:10] NOTICE[23041]: chan_usbradio.c:2845 usbradio_read:
rxcarrierdetect = 1, chan Radio/usb
[Oct  6 13:35:15] NOTICE[23041]: chan_usbradio.c:2845 usbradio_read:
rxcarrierdetect = 0, chan Radio/usb

I've already ran setup commands for rxnoise and rxvoice, etc... tx audio
sounds good along with PTT.

Here's my usbradio.conf. I'm using speaker output of a radio for now.

thanks for any suggestions.
