Well i was doing some old skool wardialin when i figured i would see what exchanges are around in my area. i checked a website(forgot name) and saw many exchanges without a name, switch type, switch location, they were just there, no one knows who owns em. i was very excited with these findings so i began to dial. first on my list was 716-958. i noticed when i called 716-958-0xxx (x being any random digit) it read my number back. and it does it with every number i scanned so far. but when there is a number besides 0 like 716-958-3xxx it doesnt work. Very odd. next was 716-927. im still not sure about this one, every number i call with this nxx will ring busy. I then checked 716-311 and 716-950 to find that when i dial a number a i get a really loud playback mesage different from the ones i heard telling me the call cannot be completed and to call my operator for help.
can anyone tell me whats going on here?
