Oh, that was just something I found, a couple months old.

Since I might want to run digital phones that far and the loop limit is about 1200-1300ft (Samsung 7200) what is the best way to get the longest possible length?

Instead of CAT3 25-pair, maybe Cat6 multi-runs or ? - wait- more twists mean more distance?

If you were trying to get the longest possible distance out of a voice cable feed for digital phones, what would you use?

Paging audio definitely won't make it that far so we can tap into a phone speaker.
