My home phone is now working with digital voice, connected to my new hub, but, Caller display does not work.
I have a list of contacts on my phone , but none of them are displayed when anyone calls. They are all listed as No Number.
Its not enabled by default, you have to add the feature yourself via the Manage BT Digital Voice option within MyBT.
