I hate the phone companies in my area, so I got internet phone service. It requries me to plug a device into the a ethernet and a phone line into my phone or wall (to get it used throughout the house). We just build our house and those jacks can run either ethernet or phone, but there is only one outlet per

We just build our house and those jacks can run either ethernet or phone, but there is only one outlet per room.

Long story short, I wonder if there was way to use them both in one jack or get a router that can routh both ethernet and phone line, or something of that nature

First we find out the difference between RJ-11 and RJ-45 cables.
RJ-45 jacks used in networking,to connect computers or other network elements to each other.It is an Ethernet cable.
RJ-11 is the cable connector that is being used in telephone sets.-It is a Phone cable.
So we cannot connect in a router.

Bottom line — you have at least 4 pairs available in every room.
You can split your cable into two RJ-11 jacks and one 'RJ-45' Ethernet jack.
You can use two pairs for Ethernet.
You can use one pair for your telephone service
You can use one pair for DSL, if you have DSL.

jeriuana:
your question doesn't really make sense ….. i think you have DSL internet service (uses the phone line). If you only have one telephone jack, but you need to connect two things (your router and the phone), you need a splitter. One side to router, one side to phone. put a DSL filter on the phone side. Then you can connect ethernet cables from the router to your computer or whatever.
?:
No. If you have DSL which uses RJ-11 connection you MUST then feed everything by wireless or from the LAN ports separately.
Johnathan:
Why?

If you need wifi throughout the house, then just buy a wireless extender. You need the box with the phone line as that is your cable modem most likely. The box with the ethernet is your router – which gives you wifi.

alvin:
Yes it is possible
Robert:
Unless you link both a DSL and a Broadband router, no, it is not.

I found this on Amazon https://www.amazon.com/RJ45-RJ11-Cable-S… So you can share. The question is, can you get one that isn't an anemic 100 base T? Further looking found this link http://www.dual-comm.com/DC102.htm

Keep looking as this proves what you need does exist.
