said by mstaszew:The only issue I had was trusting the connectors I bought that said stripping the wire was unnecessary... well... that was wrong. I tried once without stripping and no dial tone. The crimp must not have cut through the insulation. I cut off the connectors and twisted wires together to test... dial tone. Stripped wire and then used the connectors... dial tone. Modem works, etc.
That is a fairly common occurrence. It is often caused by using IDC connectors/splices that are designed for use on stranded wire with vinyl insulation on solid wire with a newer more resilient insulation.
