Hi John, some hint. I troubleshot same issue my analog line thru Audiocodes MP114 + Elastix 1.6 before. Incoming user's dtmf selection on IVR had almost 30% chance messed up/gone wrong. I used tethereal -i any -R "rtpevent.end_of_event == ture" on Elastix unix box to see what really Audio codes sent to Elastix I found out some times I capture 4 lines and some times 3 lines (when i got chance i can send you the screenshot so you know what i am talking), when user key in 1 digit. When I caputre 4 lines, things goes wrong and Elastix think it is two digits and transfer to wrong extension. i manage to reduce the DTMF duration in audiocodes to 100ms. it works well ever since.
