Frequently asked questions

What's the difference between RJ-11 and RJ-45?

RJ-11 is the smaller phone connector; RJ-45 is the wider 8-position connector used for Ethernet. An RJ-11 plug sits loosely in an RJ-45 jack but won't work there.

Why does my fax only work with the supplied cord?

Some fax devices need a 2-wire phone cord, and a 4-wire cord from another phone can stop them detecting the line.
