RJ45 is the standard used for computer networks. It is also used by many Home Automation devices. RJ11 is the standard used for residential phones lines. RJ11 connectors are smaller than RJ45 jacks and work when plugged into RJ45 jacks. Most RJ11 connectors have only four wires. Most RJ45 connectors have eight wires. RJ11 usually only supports two telephone lines. The most common used wiring standards are: T568A for RJ45 and 6x4 Quad for RJ11. The following is a graphic display of both connectors and how they can be used to work together ...

Hehe, just tried it in a RJ45 point. It does fit but didn't bother checking the connections as not fully looked into the wireing of the RJ11 cable i was testing with (it was for a modem).

Suppose, if the wireing is the same as UTP then it should do as it fitted snug.
