We have spoken many times on this forum about the flexibility of separating out broadband and voice services when migrating to FTTP but does anyone know what actually happens if you're with say Plusnet or Talk Talk with both a broadband and voice service and you want to migrate to a FTTP services with them? do they provide FTTP and cease both the FTTC and voice services?
I appreciate not everyone is interested in having a voice service but some people are and I'm curious to understand what happens with providers who support voice on FTTC but don't support voice on FTTP and what happens for those customers who are in contract and want to migrate to FTTP and still want to retain a voice service.
With Plusnet FTTP - which has soft-launched for existing (FTTC or ADSL) customers only -if you take the FTTP service, your voice line and FTTC broadband will cease. There's no pathway to extract your landline voice number and port it out to another provider.
There's speculation that Plusnet may launch a 'digital voice' service in the future, but nothing solid. I think TalkTalk have a 'digital voice' solution currently being tested.
If you're an FTTC or ADSL customer with an ISP that doesn't support voice services on FTTP (or at least doesn't yet), then if you want to keep your landline number the easiest and most seamless way of doing so is to upgrade to FTTP with a provider that offers a 'digital voice' service.
Otherwise get FTTP installed as a new and seperate order (rather than an upgrade of your FTTC/ADSL line), then once up and running port your landline number to a VoIP provider which in turn will cease the FTTC/ADSL service as well. (At present this isn't possible with Plusnet, as FTTP is only available as an upgrade to existing customers.)
If you do the above, then care needs to be taken to ensure that the FTTP order is treated as a standalone order, rather than an upgrade of the existing FTTC/ADSL line - I think at least some providers assume it's an upgrade unless told otherwise.
