Digital voice

[Burmey]

Does the digital phone physically have to be connected to the smart hub 2 or is it done wirelessly?
What advantages does the Alexa advanced BT phone have over the essential phones aside from the address book being bigger? 
How do I connect an answer phone system?

DV connect using DECT not wifi

better screen, alexa , help for hard of hearing

It is a DECT phone which connects to the Smarthub2 without the use of wires.

As regards your question regarding the differences between the phone, if you do an Internet search for BT Digital Phones you will find information and specifications for each phone.

Thanks. So not even the base station for the phone needs to be next to the hub? 
I’ve looked at the differences on,uni and I can’t see much between them. Thought there might be a game changing difference but it appears not if Alexa isn’t needed . 
If I have one of the advanced BT phones can I mix and match with the essential ones?

No, the Hub IS the base station, there is no separate base station.

yes mix and max

not sure what you mean by 'base station'  the SH2 is the dect base station  the phones only have charging stations.  if you use other old dect phones then their base station needs to be connected to socket on back of hub or use a DV adapter
