Is it possible to connect landline to router? I have archer ac1200 c6 and RJ45-RJ11 cable. When I connect the landline to the router, I was expecting it would at least power on, but nothing happens (even the screen on the phone is not displaying anything) It is Alcatel T56-CE

My current setup is Fiber Socket - Telekom Modem - TPLink router

I followed the setup from here https://www.tp-link.com/de/support/faq/3659/ for the internet and it is working.

Then I tried to set lan4 to IP-Phone, and lan3 to IPTV, but nothing happens.

Thanks
