Using ASUS modem router with vodafone fibre and home phone plan

Hi all,

I have bought a ASUS DSLAC52U modem router for home network.

I am currently under Vodafone fibre and home phone plan.

I have got the internet working, but not able to have the home phone to work.

How to make the home phone work with the new router? ASUS router does not have a specific port for the phone cable, only DSL port can be used. Thank you!
