OK, it does NOT appear in the recordings.
Here is a spectrum analysis of the call when it happened: -

OK, call recording has been setup – waiting for it to happen now.
Interestingly, before I issue the “record_session” application (and of course the “RECORD_*” variables) I had to execute “ring_ready” then “pre_answer” otherwise the caller gets silence (changing the order of those two commands results in silence).
I find it odd that just doing a pre_answer wouldn't be sufficient. A pre_answer will send a 183 w/SDP whereas ring_ready simply sends a 180. In any case, I'm glad you got your recordings. I also find it curious that only the "letter" DTMFs are being detected. Let us know if you actually hear those tones in the audio stream.
