I just tried this and it works GREAT! I used to see DTMF falsing on almost every transmission ... maybe 50 milliseconds or so when watching from the CLI at radio debug level 1. After the change, I see nothing, even when I lean on the mic and intentionally over deviate. I'm not noticing any delayed decoding of DTMF either. Thanks!

My experience always has been that the standard install is WAY too sensitive to DTMF false decodes. There may be an easier way to do this (I hope to find), but, one way is to remove the RADIO_RELAX compiler flag in /usr/src/astsrc/asterisk/menuselect.makeopts it should read only: MENUSELECT_CFLAGS=LOADABLE_MODULES
Then cd astsrc And ./configure Make Make install
There is a menu for changing compiler flags in recent releases - you have to make the menuselect program when you do the install (I think)

Hi,
I have been noticing an interesting problem. Audio drops on my repeater and link sporadically for maybe 500ms now and then as a conversation is taking place. If I watch debugging data from CLI it usually coincides with DTMF being sensed in certain voices. Is there a way to increase the time it takes for the system to recognize DTMF? Or is there something else going on.
Thanks for any pointers...
Chris
