voicemail cannot be disabled but you can setup Extended Absense, which basically do the same:
dial into your voicemail and log in with your PIN.
In the main menu, press 3 (manage greetings),
then 4 (manage extended absence greeting),
then 2 (record a new extended absence greeeting) and record a message that indicates to your caller you are not accepting messages.
Then press 4 to turn on extended absence
Finally, press 5 to dissallow anyone to leave you a message. Problem solved!
To return to receving inbound messages, should you wish to at a later date:
dial into your voicemail and log in with your PIN.
In the main menu, press 3 (manage greetings),
then 4 (manage extended absence greeting),
then 4 to turn off your extended absence greeting
After doing this, your previous personal greeting goes back into effect automatically, and callers can leave you messages again.
