Upgraded to ultra fast today and all working except the phone line.

Voice light not on and phone not working even though upgraded to ultra fast and all plugged in as should be.  I have tried to switch on and off.

Previous posts suggest there's sometimes a bit of a delay before the service is fully activated. You may want to give it 24 hours, then restart your Hub again.
