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.
