Grand Central dropping DTMF tones?

I’m setting up grand central and I have it recognizing that the 1 key is pressed and it passes along the call to my system.

Except, that when I press any number at the IVR, it is ignored. I tried transfering the call directly so I could try pressing the buttons and see if I could hear them myself, but no go. I’m not using gizmo, I’m having GC transfer directly to my PSTN line.

I also noticed that if you press any number keys about 5 times GC will disconnect the call. Are these issues new? Can anyone give me some advice?
