Porting worked fine.
Handed in the form last Friday at Carlton to port from old copper cable landline, into the Flow modem.
Got an email by Tuesday from Portingxs. I did their part, and the landline died.
Problem - it didnt come up on the Flow box, then Wednesday was holidays. Needed me to go to Carlton where they resolved the issue. Seems the number went into no-mans-land.
Now working fine.
