Who called from 2151110000

Yeah I just got it too. No caller id, no message.

No ID, no message left

Just called a bit ago, Name Unavailable, no message.

received call from 215-111-0000, Pennsylvania was caller id, I did not answer, left no message, caller calls again and again and again, annoying, never leaves message, caller calls up till 8:30 PM way to late to make solicitation calls

I just got one and I picked it up on the first ring there were some electric clicks in the background then a computerized girl said "goodbye".
