Hi all, been trying to follow guide to get VOIP working at the ONT/BTU and get rid of the Archer c5v since i have a custom router and AP

This is my current Archer setup. VOIP is working properly with the custom router


I've followed the steps to get VOIP setup on the HG8240H


And also setup vlan/WAN



I managed to get WAN connected. But VOIP is returning error


I think the voip server is looking for some signature from the Archer - whether it is MAC address, or model or something which i havent figure out.

Anybody that has managed to get this working? Help!!!

(sorry for duplicate)

I use the password given by customer service which is account number + last 4 digit phone no
