Your problem is 1.2.X. It has a poor DTMF. I broke my head for a few weeks on the same issue. (My issue was Polycom + Asterisk 1.2.X + provider X. The interesting thing is that the Polycom + asterisk worked fine. The issue I had was just when I was calling out through a specific provider.) Any other phone worked. The following patch worked for me: http://www.h6315.com/dtmf.patch

I would like to add that for some reason the patch did not work on all systems that I tried to apply it to. (I am not a coder so I was not able to trouble shoot the reason further.)
