FTTP is coming to where I live within the next few months. All well and good but what happens about your physical landline? I wonder if anyone can answer these questions:
1) Are you obliged to have a landline?
2) Do you continue to connect your wireless phone to the Master Socket or some thing else?
3) Is it necessary to change the router?
4) Can you switch to FTTP if in contract with a FTTC service provider?
3) If you have a fixed IP, will it change?
The answers depend on who your current FTTC provider is, and who you will pick as your new FTTP provider (if different).
Regarding the voice service and copper connection to the master socket:
- Some providers only provide FTTP without voice (Talktalk)
- Some providers only provide FTTP with voice via a port on the router (Sky)
- Some providers offer FTTP with or without voice depending on what you order (Zen, BT - although the BT option for FTTP without voice is somewhat hidden)
- BT may choose to provide the voice part through the router ("digital voice") or continue to provide it as analogue service on the copper, at their option. It varies.
Regarding the router:
- Some providers make it complicated to work with your own router (esp. Sky)
- Most providers' digital voice service won't work unless you use their router
If you need to keep your voice number, you may be better off migrating it to a third-party VOIP provider, although you may need to buy either a new VOIP wireless base station or an ATA.
Regarding static IPs: few "consumer" providers offer static IPs anyway. Zen do. Plusnet do, but they don't offer FTTP. If you want this, then look at Zen, or one of the more business-oriented providers, e.g. AAISP, Aquiss, Cerberus, Talktalk Business, BT Business. If you change provider, your static IP will definitely change (it belongs to the provider, you can't take it with you).
The other thing you should consider is speed. Pretty much everyone offers FTTP speeds up to 150M, but if you want faster speeds (300/500/900), your choices become more limited.
