What are you doing with these digits on the freeswitch side, what is it thinking is passed, and do you see anything in debug logs.  You also could uncomment the #define DEBUG_2833  from switch_rtp.c for more info.

Thanks for your reply,

Wireshark shows all of the digits coming through cleanly, in the case below (also on pastebin)  its 0951*72789, freeswitch does not seem to be processing one or more of the rtp events.  Is there some specific debugging I should turn on that might give me some more info on why freeswitch is not processing some of these events?

Cisco gateways can detect DTMF at random if you have kids screaming or loud noises in the background... very unreliable.

Sorry, I should have made that more clear, this is using 2833.  As I mentioned tcpdump shows all the digits coming through as DTMF events on the RTP stream (and all the correct DTMF digits are coming through).
