Who called from 3072233029

No name comes up--music played--no person--no message.  When I called back it rang once and went blank.
It was from Laramie--a  Verizon business land line.

This number calls me several times per day lately. Music is playing when I answer.

Did you figure out who it was? We are having the same problem right now!

same thing here. call ends when i pick up. rings once when i call back. two days in a row now

Called me twice this morning. Left a VM second time: Michael Buble's Moondance. Called back, rang once, 90 seconds of silence, followed by an automated voice saying "No representatives are available to take your call: Extension 0-0-0-9 is unavailable. Leave a message: *beep*"
