Be sure to turn on the RX PL filter. In usbradio.conf add plfilter=yes

If you haven't already do a asterisk -rvvv and then watch the touchtones being decoded.

The radio was tuned by a professional with tuning equipment according to the AllStar instructions. We can RX well and can TX voice well on all radios. Now the problem. Some radios (Yaesu & Icon) can send any DTMF number combination and works flawlessly. However some other radios like the Wouxun can send any number but the number "3" key successfully. For instance \*81 gives us the time successfully but 3 used in any string doesn't work. I have modified only two usbradio.conf settings:
