OK, OK, we are using the terms incorrectly per the USOC standard, however, this is "common usage".  The articles in the following links may help to understand the differences between an RJ11 and RJ12 (or 14 or 25) connector, or not!

However, in the interest of simplicity, Midon Design has chosen to refer to the connectors used on our products as RJ11 for a 4 pin device and RJ12 as a 6 pin device.

Readers will note that there are differences of opinion as to what to call the 6 pin socket, however, outside of the telephone industry, technically none of the connectors should be referred to by the RJ designation.  Practically, this is not the case.
