Hi, @TINA72, it's not something we can do from our side.
Is there no dial tone whatsoever, or are you having trouble making/receiving calls?
We can talk through a bit of troubleshooting from our side. First things first, we'll need to confirm that the base of the home phone handset has been plugged into voice port 1 or 2 on the back of your Optus modem.
You'll need the grey phone cable with the white tipped connectors.
If everything has been set up correctly on your side, it could very well be an issue on our end. It could be a matter of us pushing the order through to completion. There's normally a slight delay between the activation of the broadband side of the order and the activation of your home phone service.
You can message our activation team here. Select, personal → Home phone, Broadband & NBN → Track my order.
