[arm-allstar] DTMF problem

[Doug Crompton]

Wade,

 It is very unusual for DTMF to not show something in the client even if it is wrong. 

asterisk -rvvv

This is what you should see as you hit each tone -

This was done with a Baofeng UV5R with feedback turned off and it has always worked perfectly. See below.

I find it very strange you are seeing nothing. Have you tried other radios? Levels and pre/deemphasis are prime problems. Levels should not be that critical in most cases though.

Are you sure you have node radio RX audio to Allstar? You are seeing proper levels in item 2 of simpleusb-tune-menu ?  5-6khz peaks?  If you hit a DTMF key on the input radio can you hear the tone on the node radio speaker?

Baofeng radios can be a problem because if you don't mute the tones to the speaker they are picked up both through a direct route and thru the mic which often causes failure to decode. 

See this -
