My current house has all the phone line wiring done up nicely (RJ11 socket in the wall, etc), upstairs and downstairs.

Since I'm terminating my streamyx and upgrading to unifi soon, I wonder if I can re-use the same telephone lines for the same phones in my house?

Is it possible to plug in the phone cable from the BTU to the phone jack in the wall, and then all the phones in my house will work?

thanks.

yes, they will pull fiber for me. then the fiber will go to the BTU. but my question is, my BTU is going to be upstairs. i have a phone jack in my wall. can i connect the BTU to the phone jack in my wall and my downstairs phones will have line as well?

Ah ok, got it. Thanks!

Yes, from btu (voip) to phone jack, phone jack connect to dect phone downstairs.

rockylabu: yes, my house is already wired. so i'll give it a try!

thanks for the reply guys.
