Maybe 'BT were the only ISP to offer FVA'
Is morphing into
And FTTP can be ordered without POTS and will have a VOIP interface on optical modem ONT.
There seems to be some confusion.
This is how it is currently and how it has always been on FTTP.
FVA
is VOIP via the ATA port.
A bog standard run of the mill telephone is connected to the telephone port on the ONT and voice is provided via VOIP.
Currently you can order;
FTTP with data only (no voice service at all)
FTTP with FVA (VOIP via ATA port on ONT)
FTTP with voice via POTS
Stopping POTS in copper only areas isn't going to happen for years. What is the alternative for voice?
Stopping POTS in FTTP/copper mixed areas isn't going to happen either.
Many many ISP's (Talktalk, Sky, Plusnet) don't even sell FTTP so stopping POTS would effectively preventing them selling voice services in areas with FTTP.
Obviously there is no POTS in FTTP only areas.
Taking all the above in to account under what circumstances could they put a stop sale on POTS?
