Is that different from the landline service they offer directly from the ONT? My Openreach ONT has a telephone jack as well as the RJ45. I've never actually used the telephone jack, but I'd imagine I would get a voip-backed fake dial tone if I did?

I used to have BT Broadband FTTP in a previous house, which had a bidirectional fibre into a box of some sort, which was battery powered, and went into another box which emerged as a telephone jack, and an RJ45.

This was 2016. The battery box was there to provide power and service for a landline in a power cut.

My router plugged into that RJ45 with a pppoe client, username "[e-mail]" and looks like any old password ("BTSux" for example)
