Called us, left no message. Smells like a telemarketer.

Called, rang three times and my spouse slammed the phone down.  This WAS a verizon wireless phone number but is now not in service, disconnected or changes.

Called today. Didn't pick up. They didn't leave msg.
CID said "CALIFORNIA"

 They called and I answered the phone.  I hung on the line to try to find out who was selling what, but never heard a person come to the line.  They hung up after 1 1/2 minutes.  Did hear some background noises so it appeared someone was there.  CallerID simply said Cell Phone CA.
