We had fibre to cabinet and took fibre to property when contract came up for renewal ( my DH didn’t actually take the time to understand why he was signing up for, but that’s another subject and I took over management. )
It has been a PITA as the old router was on the top floor, custom wired unseen throughout the house when we were renovating , which we could no longer use. The new router is now downstairs . The old router gave solid fast coverage throughout but we’ve had to buy a disc extender fo the new feed to get my DH’s PC to work upstairs. ( You can get these on subscription but I calculated it to be more expensive above very short term) The broadband speed records as fast but I notice a slight delay.
Anyway, to get back to the Voice. The fibre comes into the house low down via new cabling from the telephone pole opposite - it comes in at a different point from the copper wire telephone line. We assumed the Openreach engineer would take out the old copper wire from the pole to the house. He left it and said vaguely it would stop working at some point. so we’ve got two lines coming into the front of a small Victorian terrace, at different points.
The landline is still working, in and out on the copper wire. We tried to get it working via the new router by plugging in the DECT compliant base telephone as per instructions but to no avail. It’s not the biggest problem for us, we have a short term need for landline which should be solved soon. We also now have an unused telephone extender for the digital voice that is redundant at the moment. So we have the odd position of fibre broadband and copper wire telephone coming into the house.
I did ask the engineer what would eventually happen theoretically about houses in the street that I knew didn’t have broadband currently and didn’t want it but relied on landline and he said they would be supplied with a digital landline version. Who knows what exactly that would mean 🤷🏼♀️
