+16472306677, 1-647-230-6677 did show up twice on my call display as a long distance number. I am in the GTA and all other local 647 area numbers display as local numbers without the 1 prefix. Called back 647-230-6677 rather then 1-647-230-6677 and got a message that they are unable to receive my call. Very suspicious!
My cell's number starts with 647.230 as well - received four calls from 647.230.6677 during the last week. Called back twice and also got a message that the person who 647.230.6677 belongs to is unable to receive my call
