Also yes you can simply plug the RJ11 output of a VOIP router into a wall jack to
feed the light up the house phones.

That's only true if you want to use a certain implementation of VOIP.
Implementations that ride over an internet connection using a PC (like
Skype, Google Talk, and many others) don't need such a thing (or use
something like a USB dongle).
I assume in this case you asked the question about replacing your standard
phone line with a VOIP service? If you are getting your Internet service
over cable, then you need some way of taking the phone traffic, digitzing it
and converting it to TCP/IP packets and then doing the sending/receiving
over the cable. The VOIP router would do that.
