I'm having a wierd problem. Somewhere around 1-2% of the time, the first DTMF digit dialed gets dropped. This is occurring during a SpeechBackground application call. If the caller reenters the digits when given a second chance, all is OK. Any suggestions how to debug this intermittent problem?

I play a lot of my speechbackground messages with beep in front (speechbackground(beep&foo)) so my user doesn't start hitting DTMF until the message starts playing.

[asterisk-users] Losing first DTMF digit (with ASR)
I have seen simalar issues with some audiocodes gear. I adjusted the early media options on the pri in the audiocodes gateway and that fixed my issues. We have also seen this when calls come in from Level 3 toll free some times their gatways screw with things. We found adding an manual answer and then a few seconds before the prompts solve the issue. Somthing about how Level 3 injects rfc dtmf and some packet time stamp issues.
