Rather than the Silent feature on your phone use the Do Not Disturb setting. Can be programmed to allow family and work calls to ring through but not ring for the spammers while you are sleeping.
Here's the Apple version, I am sure other platforms have a similar feature.

Interesting. Thank you.
my problem for about the last year has been the NRA. ive asked nicely and ive been mean. but they will not stop. it went from a call each day to 3-4 calls from different numbers every day. even on weekends.
I let my membership lapse for a long time for this reason. I rejoined with a Life of Duty membership and have not had the daily mail or phone call issues with it for some reason.
