Who called from 7345489858

Called my business line. No one on the line when I answered. Called the number back and got "all circuits are busy now" recording.

As usual, a one-way botherer. They can bother you with several calls per day, but you can't reach them.

Called a few times, no message left, no one on the line.

No one responds when you answer and then after several seconds, they hang up.  Probably harvesting contact names so other telemarketers can ask for you by name.

I just got a missed call from them. Blocking them.
