Talktalk haven't even trialled VOIP yet and still don't have hardware with a VOIP port.
I'd be amazed if they launched a VOIP product before 2022.
I'll eat my hat if it's released by August.
Well that's 2021 over with. I don't need to eat my hat then
On a more serious note Talktalk (consumer/residential) finally started trialling their VOIP product earlier this month.
The trial is only open to existing FTTC customers who upgrade to FTTP.
They won't allow existing FTTP customers on to the trial at present.
