Repeatedly been getting calls from this number.  No one on the other end....silence.  Then after 10 seconds, a hang-up with fast busy signal.  Calling the number back results in either a fast busy signal, or a recorded British accent message saying, "the number you have called is temporarily unavailable...please try your call later", then hang-up and fast busy signal.

There's got to be some way to trace these calls and get to the phone spam person or group that is originating them!

Phone rings and this number pops up several times a day. (I no longer answer.) The caller is listed as "Professional MC". I did dial the number once and a female voice with a British accent said, "The number you have called is temporarily unavailable."

same story, no idea of caller, would block if att would let me

Called me several times, but voice mail answered
