Hung up when I picked up

Rang about a half a ring, no message. Looked the number up, seems to have belonged to a law office in Pittsburg at one time.

calls once a day while I'm at work, no message.

Called and asked for my wife by name. Told them she wasn't home, told them I was her husband, asked if I could help and they abruptly said they would call back later and hung up. My wife had a minor car accident and was rear ended, no injuries.  She just reported it to the insurance company the day before they called.  Did a Google search of the number and it appears to belong to a law office - apparently a bunch of ambulance chasers.  

Political Campaign number.  Call it and you can be added to do not call list.
