Hi asus support,
I'm on Maxis Home Fibre and using ASUS RT-AC68U as the replacement router. I'm following the setup guide as provided in the video below:

The setup was working fine for both phone & internet but recently, the phone is not working. Only the internet is working.

Called Maxis technician and they revert back everything to their original setup (without the Asus router) and it work fine for phone & internet.

How do I get both the phone & internet working with the ASUS router ?
