I have a VVX 601 with the Genband Kandy platfor that is not registering DTMF tones properly, It is not all DTMF IVR's, just certain ones, I have dialed the DTMF test line, and it is registering properly there, but not on all sites. I have played with the parameters, and could not get it to resolve this issue. This is with the 5.7.0.11768 firmware.
