It will work fine.  Just be sure to use one pair for mic and mic return
(pin1 and pin 7) and one pair for PTT and ground (pin 2 and pin 8).
The other pins can be any wires but using twisted pairs for mic/mic
return and PTT/Ground will provide the best balancing to reduce any
hum/RFI issues with the unshielded cable.

If you can find shielded CAT5, connect the shield to the connector
*SHELL* only on both ends (do not connect it to either mic return
(pin 7) or ground (pin 8).
