If you plug the splitter into the wall jack (without involving the ont) and you see line in use on the phone, there is another phone line on that wire. Are you sure it's completely off on what used to be the dsl line?
Things to test:
- plug the cordless phone directly to the ont.cordless phone should work.
- plug the cordless phone and ont on female ports of the splitter without plugging splitter into anything. corldess phone should still work.
- make sure home wiring has no phone connected and is disconnected from old phone line and plug the splitter (with ont and cordless phone on the female ports still connected). it should still work.
-disconnect the cordless phone and plug it into one of the phone outlets in the house.
If it does not work at any step. do the same with the corded phone.
Although our house has phone wiring throughout, what we did is leave the cordless phone base near the ONT in the basement and use cordless handsets with chargers in the house (uniden 5.8 GHz multi handset phone system) and it works well.
