Dialpad not working after Recieving Call?

[gullzway]

I'm having a problem with not being able to press a number on the dialpad after receiving a call. I can use the dialpad just fine to make a call!

Specifically when I use my Google voice number to dial a number, when I get the Return call from Google voice it asks me to Press 1 to accept the call. I press 1 over and over but it doesn't register so the call hangs up.

But if I go back to the dialpad I can easily place a call again??
