I use Google Hangouts and Google Voice for all of my calling and texting. No one has my real phone number. For example, if my cell phone's real number is 212-555-1212, the only number that people see is one of my GV or GH numbers (e.g. 212-555-2323 or 212-555-3434). Previously, on an earlier version of Lollipop, one could set all calls to the cell phone number to auto-reject (not just specific calls) using the native Phone app. This would prevent me from receiving any unsolicited calls since those calls all would be to the cell phone's real number and not my GV or GH numbers. This option is no longer available in either my wife's phone (running Lollipop 5.1.1) or my phone (running Marshmallow 6.0.1). Does anyone know how if this specific feature is available in Marshmallow? If not, can anyone recommend a third-party app which can do this?
