I have just signed up with NBN. I was hoping to get my phone number ported over, and noticed that the modem already has this number configured. Unfortunately due to a misunderstanding my number was disconnected before the porting could happen so TPG have assigned me a new number. Shortly after this I got an email saying everything is done. However my new number still does not work, and obviously neither does the old one. I noticed my modem still says the old number, how do I change it over? I tried rebooting it but no change.
