Other websites list this number as "suspected spam." I have received calls from a similar phone number (901-300-7417) which has been reported here at 800 notes as a bogus telemarketer.
Recorded message saying that I'd just won a free cruise to the Bahamas. Immediately hung up after that. Caller ID labeled as Memphis, TN but I'm sure they're just spoofing the number.
I keep getting calls every other day from this (901) 300-7420 number and they won't stop doing it. I ignore the call every time and they've called about 8 times already. Also, they never call me at the right time either. They'll either call late at night or early in the morning.
