HTC One touch tones don't work on calls

[mromane]

I just purchased a new HTC One this weekend. While trying to get on a conference call this morning, my concall service couldn't recognize the access code. If I was lucky, they would recognize 1 or 2 of the 6 digit code. Even when trying to let the system know that the entry was incorrect, it couldn't recognize me simply pressing 2.

Do you think the phone simply needs to be replaced or is it a software issue?

Thanks for your help!!!
