The leave behind option was offered in situations where VOIP was not possible at the time, @DJI_MINI_2_SE - not so much because people preferred it, but because VOIP was not available.
The problem, now that Talktalk has to get all these people switched over to a VOIP inclusive product, is that they can't keep up with demand.....of course people rushed to apply to avoid the £12 extra per month [and that's before calls after all or the boost]!
If copper leave behind is the only option at the time of ordering, then the line is likely to still be inclusive in the package fee as now - you'd need to check that detail for them, and, as always, speak to an agent directly through phone / Chat.
Don't do a single click order through My Account etc as these don't detail the nuances of the package. You'd want to check TV charges; voicemail charges; supersafe etc, so all the fine tuning of what is or is not included.
Remember also that there can be mid contract admin charges etc, if not a set up fee.
Think carefully about the speeds they would really need - the simplest router comes with Full Fibre65, so, if they don't need faster than that, they can simply plug the landline into the socket at the back of the router. That's more straightforward than the Digital Voice Adapter and Eero etc.
But it only allows one plugged in phone. Their traditional extensions won't work, but digital phone sets will.
But the big but is suitability with panic buttons, or other alarm systems in their home. For the elderly, it's worth hanging onto their FTTC for as long as possible to give all the technology for all the safety gadgetry, time to catch up with the consequences of VOIP, and VOIP to catch up with the needs of the elderly.
