I received a call from this number. No message was left. I love my Android's black list feature. I just add their number to it and I never know when I get a call from them again. There is a log that shows they called, but my phone does not ring or interrupt me. One call from any new solicitor, add number to list with a couple of swipes and voila! Out of sight - Out of mind!
They have often called. It's the Colorado Symphony Orchestra. We bought tickets this year and now they have apparently engaged a paid fundraiser. I doubt they aer covered by the Do Not Call list rules, as CSO is a nonprofit. She was quite polite and agreed to remove my name from her list.
Don't provide your cell phone # to arts organizations when you buy tickets from them, duh. Non-Profits do not have to acknowledge the DO NOT CALL REGISTRY also.
