This is an interesting problem. I never hear this on any of my nodes. Could it be that there is too much audio driving the URI? Not sure, but does the URI RX level drive the DTMF detection? If so, you might be too hot.. Might be worth trying to adjust that down as a test to see what happens? -----Original Message----- From: app_rpt-users-bounces@ohnosec.org [mailto:app_rpt-users-bounces@ohnosec.org] On Behalf Of Tim Sawyer Sent: Sunday, December 18, 2011 11:25 PM To: Ken Cc: App_rpt-users@ohnosec.org Subject: Re: [App_rpt-users] DTMF voice falsing I tried removing RADIO_RELAX but touch tone decoding was way too slow for my taste. Jim mentioned that the parameters could be adjusted to perhaps find a happy medium between radio_relax and phone mode. The parameters are in /usr/src/astsrc/asterisk/main/dsp.c under the RADIO_RELAX compiler directive. Not being a C programmer and knowing even less about the DSP routines, I couldn't make much sense of the values. But maybe others could check it out and explain the parameters to the rest of us. :-) -- Tim :wq On Dec 18, 2011, at 8:05 PM, Ken wrote:
In my case, the DTMF commands work fine with this setting.
The only time I have trouble is when there is some multipath distortion ... driving to the next traffic light is usually enough to fix that ;-)

But can you still reliably function the system? -- Tim :wq

Ken,
Your suggestion made a huge difference!
Thank you.

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
