Just got a call on home office phone.  Did not leave a message

Last call came in at 943 A CDT, Caller ID showed "Unknown Name". We have had repeated calls, 2-3 daily, since June 28th from this number. The phone doesn't ring since we have the number in our Call Blocker unit, but it still appears on our landline phone Caller ID display. Even before they were blocked, they never left a message. As long as they keep calling our number and get blocked it is just one less call someone else gets.

Just got a call.  Finally decided to dial the number back, and it was from March of Dimes, so I hung up before a human voice could answer.  I, personally, never support a charity that pays a large % of it's donations towards these call centers.
