Hi I dislike receiving calls from withheld numbers. My ideal application would be one that allows me to record a message (for example, "You have chosen to block your number, so I have chosen to block your call - please redial and present your number") and play this to anyone who calls from a withheld numbers. I don't want to be notified of calls. Does an application exist for this? I can't find anything in the App Store. Does anyone know if one is under development?
