I still have 2000+' of XCW to use up! I got lucky on the last one, the Mitel SX-50 had a much larger field and I moved to 2 66 blocks at the beginning of the field so most all of the jumpers were rip off from the Mitel and move to the Yeastar.

I only lost a couple of extensions.

I also have some 2-pair and 3-pair and some Cat-3 (looks more like zero) jumper wire.
