Appears to be a spoofed number, robo-called on a tie-line, one of over 30 numbers pegged to a notorious scam gang. Blocked.

Guy uses a wide range of similar numbers from 703-382-6417, 6418, 6419, and upwards,  and has been calling regularly.  He says, "Hello this is Joe. This call is being recorded.  Can you hear me?"  Don't want to say yes, as it may trap you into a sale.  The latest caller ID is 703-382-6425.  The called ID displays Springfield, and I'm assuming it's VA because it's close to my location.  He has been calling for months now, and I recognize his voice right away.

Reported the many numbers to the FCC.
