Someone called from this number. The number did not display, but the phone "spoke" the number and when I picked it up, there was no voice on the other line - although it looked like the line was open. Then while I was looking up the number, another call came in - this time the phone reported "private number".
I immediately asked who was calling and the voice (thick Indian accent) said it was Dan Johnson from Alarm Security (or a similar name). Funnily, a few days ago a Dan Johnson called from another company.
I said as much and the caller said no. I said yes it's true and the caller said "sorry" and hung up.
