Digital Voice Phone Registration 'Order' to SH2 Router - Call Blocking - Different Models

[Brian12]

 In a situation with multiple handset phones of 'differing models'   -   'Advanced' Answerphone ; 'Essential' Phone ; 'Advanced with Alexa',   with regard to 'Call Blocking.'

In order to get the most protection, would it be better to link them to the SH2 router in the order of best 'filter phone' first etc. ?  and will that best 'filter phone' work to protect the other phones ?

Or doesn't Digital Voice work in that way ?

Thank You

Hi @Brian12 

You can only register Digital Voice handsets with the SH2, other handsets would need to be connected via the phone socket on the back of the SH2 or I think DV adapters.

If Call Blocking is your priority then it would make sense just to only use the handset that offers the most protection, or  use BT's own Call Protection service which would be simpler I think.
