That's very interesting, Nathan.
Now that makes three of us, two using the Digium cards and one using a Sangoma.
It very much looks like something FreeSwitch is doing, perhaps the DTMF detection is far too sensitive? Are DTMF tones for an ISDN line inband or do they come in on the D-channel?
Michael - any ideas what we can all do?

I'm having the exact issue you're describing, with the same card. However, what's interesting to me is that if I fire up Asterisk instead of freeswitch, the phantom DTMF problem disappears entirely.
So it's *something* inside Freeswitch, at least for me. Would be interesting if you're able to do a similar test.
