I keep getting this number calling my phone. I tend to ignore it...and they never leave a voicemail. Once my 4 year old answered it and I took it away from him and no one spoke on the other end.
Obviously a spoofed number, given the 555 prefix. Called my wife's cell during dinner. Then, not ten seconds later, my own cell rang, but with a different calling number: 240-874-5523. I think someone must have been going down a list of names and addresses.
