Hi Folks! everyone I know has the same issue with unwanted spam calls. for those who must answer the phone, they are life's bother. for many individuals, there is no reason not to make such calls simply disappear. Blocking a number is fruitless and useless - the spammers spoof their Caller ID for (nearly) every call. Do Not Disturb mode has changed over time, in the latest I had it set to allow only calls from My Contacts. Oddly enough, altho phone calls come through from Contacts, no alerts for text messages from Contacts comes through. Why Apple decided I might want them to be able to call me but not text me is one of those great corporate mysteries.... Next, downloaded and set the default ring tone to Silence, set a ring tone for each Contact - which lets me ignore spam calls. then had to turn Vibrate OFF because, unlike Text alerts which can't be turned on for Contacts, Vibrate cannot be turned OFF for non-Contacts. similar suggestion here: Do Not Disturb mode as a call blocker What would make my day is an app which screens calls and unless the number in in My Contacts: it doesn't ring doesn't display doesn't alert / does not do Reminders does not appear / gets auto-deleted in Missed Calls allows non-Contact caller to leave a voice mail. anyone with a legitimate need to contact me will leave a voice mail; and some without a legitimate.....oh well... but other than that I don't want to know about or have to deal with deleting multiple/many spam "missed" calls a day. the Missed Call list is apparently finite - it will fill up. and the Delete All function, altho quick and easy, deletes the records of all inbound/outbound calls - some of which I might want to keep. anyone aware of an app that does this? is it possible for 3rd party apps to address/manage that level of the iPhone system? who wants to write an app for that?
