CallerID has been masked as only "I"

Multiple calls at random times all hours of the day with no message left.

Calls all hours no message left.

Numerous calls all day from "I".    Leaves no message.

After these [***] called me 3 times today while I was trying to sleep I added them to my blocked calls list. *60 has saved me a lot of grief. Now there are 12 [***] offs on the list and there's room for me.  When THAT doesn't work I simply have the incoming call forwarded to either their own number or something like a funeral home or pest comtrol business OR I forward it to a fax number.  That annoying fax tone should give them a hint that I don't want to be bothered.

My elder person said this was a police person begging for a donation. She hung up on them.
