I'm helping out a church with some technology issues. As of last week they had a threshold with two cables running across it: a phone cord and an ethernet cable.

Last week I re-ran the ethernet cable (with MUCH difficulty) and it looks much better now. However, the phone cord runs a different path and cannot be run the same way. There really aren't any options to run this cord through the walls or any other direction across the room, and they need it to get from the phone jack to their copier so they can use it as a fax.

I'm worried about using those powerline phone jacks because this church has old wiring and I don't think it would work well. Are there any other options?
