Better than two cans and a taut string!
If you're constantly battling with your phone or fax placement; always at the end of the coiled cord tether or sick of the long walks between your desk and your equipment - don't get mad, get even! A 10m RJ12 male to male telephone line extension is just the injection of copper wire the tech doctor ordered.
Suitbale for all modern telephony devices and newer homes with RJ12 wall sockets. Don't put up with the poor placement of phone sockets in your home, rental property or unit! A few dollars invested on a cable will make life easy and you can take it with you if you move!
