I've ordered Infinity and as a result the BBT has been switched off instantly! Even though the install date is over two week's time.
Anyway, I never use the Landline number (it's there to provide the broadband & we used to get nuisance calls) always the BBT number.
Is it possible to 'port' the BBT number to the landline number?
Do you use BBT on any other devices, eg running Softphone on a PC, or Sipdriod on an Andriod phone. If that is the case, you can have the BBT restored.
Which version of the home hub do you have at the moment. If its a version 1.0, then it can still be used as a slave to provide BBT?
