BT FTTP ( without a voice service) could be ordered in addition to the existing set up , obviously more expensive than everything delivered over one FTTP connection, but telephony over the copper pair is closing, getting FTTP to replace your FTTC ( rather than FTTP and FTTC together) affords BT the opportunity to move you off PSTN now…as a way of ensuring no loss of phone number or broadband you may need to keep both FTTP and FTTC for a short period…or simply cancel the FTTP and hope your current setup remains, but in the knowledge that by 2025 traditional telephony will be history.
DV is BT’s optional proprietary telephony service , it’s not compulsory , it requires you you use the equipment supplied , don’t want to use BT SH2 , that’s OK for broadband , but you cannot use DV, so no point in getting FTTP with DV, FTTP without telephony is a little cheaper as well.
It may be a little late to do this now but porting the number to regular VoIP provider would allow it to be accessible without including the SH2 in your set up , but will still make the copper pair redundant, assuming you keep FTTP.
Interfacing your VoIP service ( either DV or a third party VoIP provider ) into your internal extension sockets is not your providers responsibility, it can be done , they even provide some equipment free to enable most consumers to do away with wired sockets , obviously some situations may not be as straightforward as replacing wired sockets with cordless DECT phones.
In the short term , if it’s essential that the SH2 isn’t incorporated into your network, you probably need to cancel your FTTP ( if it’s not too late ) and consider carefully the way to proceed, FWIW, it also appears that if you port your landline number to a VoIP provider , that will cease your FTTC that would need to be reordered with a new number ( that you don’t use ) or get FTTP without any phone service .
If you were starting from scratch, you order FTTP without telephony as a stand-alone service in addition to your FTTC , you migrate your non telephony onto this , you then port your number to a VoIP provider , this has the consequence of closing your FTTC service , you are then responsible for making the VoIP service accessible from your existing setup….don’t mind paying more than necessary, keep the FTTC as it is as well as the FTTP , but in the knowledge that at some point in the near future and by end of 2025 at the latest your phone will no longer plug into a copper master socket but a router of some sort.
