Punchdowns are probably 50%-75% the cause of all troubles in these types of installations. I very much dislike them. Even for dial tone they are problematic. Wirewrap never seemed to fail.
If they were brand new when installed , punched correctly and nobody ever ever ever touched one single wire on the block ever again, they are fine. But that never happens, techs get the wrong wires when troubleshooting, they tug and pull on stuff to figure out where they are and they re-punch wires during troubles and installs. The piggy-back jacks are nice and quick but you still have a fricking punchdown behind them. I have used them for dial tone on PBX s but not for data.

I'm about to convert this wiring to Ethernet for VoIP. Can I take the easy way out, remove the jumpers, and install the piggy-back jacks, or should I really pull it all and punch it back down on a proper patch panel? Don't want to cut corners, but if re-punching the whole lot can be avoided, it would help cut the customer cost.
