Starts speaking before the answering machine is done with the announcements and identifies as AMSG (reported by other call recipients as standing for Asset Management Service Group).  The rest of the message is:

"…press 1 to be transferred to a representative.  If you are not available at the moment, please return this call immediately.  The number is (855) 323-8822.  Again, this is a very important matter. We must speak with you immediately. Thank you."

I have received the exact same recorded message from different numbers with the following caller IDs: Jonesboro, GA; Jackson, MS; and Vocalocity, Inc.

I also received a call with the same phone number with caller ID of UNKNOWN, which left no message.

Less than two hours before this call, I received a call from my own number and caller ID.  I'm sure it was from these guys, spoofing my own number, as well as numbers all over the country.

Please note that I know from an extensive credit report AND background check, which I requested at a U.S. government office, that there are no collectible debts pending against me.  I always ignore all of these calls.
