No busy signal for incoming callers when I’m on the phone

[MnB]

Are you able to enable our busy tone for when incoming callers phone us but we’re on another call? At the moment it just rings out for them,
We are on NBN Cable 50.

Hi @MnB, 

We'll request for your call waiting feature to be disabled. Can you please send your TPG landline number via private message?

Regards,

Angeli
