If you're in the US you receive about 3 spoofed "spam" calls a day telling you the IRS is sending the cops after you, that you need to pay for Mandarin classes (in Mandarin), and "Vacation Opportunities"... so the idea that spoofing a telephone number is difficult or rare is obviously untrue. The idea that an automated read out of an address (especially any number) makes capture difficult is a little strange. If nothing else, hire Mechanical Turk for 5 cents. What the value of the information is (and whether it's below cost) I don't know, but the fact that you have Comcast shows that you have a fair bit of disposable income ... so whether it's another spam call to a known good number in a targeted location or just to check if you're home before you're robbed... I'd say it might be worth at least pennies.
