FTTC + voice calling (SOGEA + voice) would allow customers to do away with their landline if they wish, but also still make calls via a voice service over their internet connection (and keep their old number, ideally).
Not sure if this would save Cuckoo much money, vs paying line rental.
But if it did, maybe this saving could be passed onto customers, which would make Cuckoo internet both a better deal for customers (due to no contract), and allow prices to be lowered a bit, making them even more competitive with large ISPs. Presumably, this would also allow for much cheaper calls, vs calls made over landlines.
One thing I don’t know is, would this require a new Cuckoo router to add support for making and receiving voice calls? Would engineer visits be required?
All premises are planned to be upgraded to either SOGEA (FTTC) or FTTP for voice calls, by 2025 (2023 in areas prioritized by Openreach for FTTP), when BT intends to stop offering traditional landline services, so adding an option like this now would be quite forward thinking.
One example of SOGEA + Voice is discussed on this website:
It would be interesting to hear Cuckoo’s thoughts on this.
