Good afternoon! I know how important your voicemail messages are important to you and I want to help with your concern! Do you recall when this began happening? I recommend pulling the battery from the phone, while powered on, and leaving out for about 20 seconds then reboot and reattempt access to your voicemail. Does the dialpad freeze when dialing out a normal call too? Or when you are trying to use other touchtone automated services? Another suggestion I have it checking the DTMF tones under Settings> Call Settings> DTMF Tones>Select 'LONG' from the options. This will provide a longer tone to the automated system so it picks up easier. Please keep me posted.
