Unwanted calls. Don't know the caller.

Left no message

Received a call from this number. After several seconds a message comes on: "Due to an unexpected volume" and then it cuts off. I waited to see if anything else was coming, but then the line went dead. Are they fishing for live numbers so they can sell them to other tele-frickin-marketers?

Had the same experience ,"Due to an unexpected volume " and then the line went dead at 6:55PM March 06/08.

"Due to an unexpected volume" was heard when I answered the phone and then line went dead.
