Hi Peter,

Yes the tones are valid themselves but I'm sure my customers aren't randomly pressing A-D on the phone which doesn't even have them on it!

I'm also seeing other tones as well including the numeric values all where are falsely detected.

It is 100% safe to assume that Joe Q Consumer is not dialing DTMF A, B, C, or D. This is definitely an issue somewhere in FreeTDM.
