Hi @RayChen . It has been mentioned before in Community that you can have two NBN connections with FTTP. The FTTP NBN box has 4 UNI-D ports. Don't know how the VOIP phone function works with multiple connections.
Look at this article:

There might be restrictions on max speed with more than 1 connection.
When applying for the second connection, you would need to stress that you are applying for a second connection, otherwise the second provider might just churn your existing connection to them.
