One of 3 calls I got today within a 1-2 hr span, all from #s across US I don't recognize. And all 3 have similar reports on them (looks like someone sold my number for telemarketing / scams! Grrrr!)
I too got a call from this number, on my cell phone, whose number is unlisted and unplublished. Very few people have this number. I did not answer the call.
I doubt your number was "sold for telemarketing/scams" - many scammers use autodialers to dial all possible numbers in an (area code) + (exchange) hoping someone gullible will answer. Anyone can call your number, accidentally or on purpose. What is special about your number is the association of your name with the number. The low-budget scammers won't have name information.
There is also the possibility this number ( 903-200-1587 ) is spoofed. There is a lot of that going on too.
