When I am in voice mail and someone calls my keypad is no longer active. I can no longer push any buttons to operate through voicemail. For example the number 7 deletes messages...Before someone calls this feature works great. If I am in voice mail and someone calls I can longer use the 7 key to delete in fact I can't use any function keys to manipulate anything in voice mail.
How acn I solve this issue? I am in and out of vocie mail all day. If someone calls while I am in I have to hang up and dial back in to be able to use my keypad and function in voice mail!!!
