This is a number used for some scam "online pharmacy"-location Rutherford, NJ...they had been calling continuously from another 201-340-number, but I blocked them (*60). They ignore polite requests to remove my number from their lists and quit calling, so I have changed tactics.

This time, I answered and let the Who's "Who Are You" blast into the mic. Then I blocked their number and called em back a half dozen times and blasted more Who into the mic. On the 7th call back, I spoke and told them to quit calling. A heavily accented voice on the other end requested "you quit calling me muther f***** ".  My reply, "f*** u" and called em back a few more times with more Who blasting into the mic. Presumably, they will get the message this time!  A poster on another site reported success using an AIR HORN on them!
I agree 110% with Rick's sentiment...

its a phone call people you have WAYYYYYY to much time on your hands, enjoy life.... if the phone rings we ARE in the 21st century heres a tip... DON't F'IN ANSWER (that's what I do... instead of wasting my own time playing music into the "Mic" THEY get paid to take the calls you DON'T so who's the A******e???) And Rick your probably some pimply faced 13 year old, anyone that threatens the life because they got a phone call should PROB be in a mental hospital.... I get calls all day for random stuff.... WHO CARES, If I don't know the number I don't answer, I WILL NOT waste my time calling them back repeatedly to play music in the phone... God us Americans have become so ignorant.... enjoy your welfare, since you have so much time on your hands you can do that...

I get 2 or 3 calls a day from this number  and no one leaves a message or will answer when I say hello

Have had a few calls from this number, leaves no message and has hung up on me without uttering a sound. Going to block this number.

Same thing. Calls  about every other day, no messages. Annoying.
