Hey guys, glad I'm not alone. Timing sucks, when I posted the first message, I had some time to burn and debug, but then one thing lead to another and then, pow, no more time this weekend. I'll try to set up shop this evening, but I think it's something to do with something that's changed in the code. My friend can connect via IAX2 to the same box and his DTMFs are read perfectly.
