Help me diagnose a CAT5e UTP cabling gremlin

I have two RJ45 outlets in one wall plate, labelled B-01 and B-02. An analog phone that worked for several years when connected via B-01 failed spontaneously; a quick test shows that it now works reliably via B-02 but cannot be persuaded to work via B-01. And yet, a PC with a gigabit Ethernet connection still works via either, and the TDR cable fault tester in the local network switch returns identical results for both. What am I missing?

Telephone over Cat5: Is it possible without voip?

I'm setting up some telephone lines, and well, I really don't want to lay more wires than I have to. So this is the deal, I've got five telephone lines, and three telephone (rj11) jacks. We've just installed wifi, and so a number of unused ethernet cables. Is it possible to buy an adaptor that will allow me to use a cat5 cable to send plain old telephone over them? [more inside]
