Ok, next question. :-) We just deployed a beagleboard with URI as a mountaintop repeater. It's mostly working great. One problem we just discovered is with the phone patch: dtmf digits are frequently getting doubled. E.g., "510" as an area code will show up as "5510" or "5110", causing the call to fail. It happens about 30-50% of the call attempts and on different radios (Kenwood and Yaesu HTs, ditto for mobile rigs). I used susb tune to adjust the rx audio level for 3 kHz, so I don't believe it's something like bad audio volumes being fed into the URI. Any ideas for places I should look or things I should tune? Thanks very much! Phil, N6TCT
