How do I know when change from FTTC to FTTP is complete?

davec13 — Tue, 23 Jun 2026 20:23:41 GMT

I have just been upgraded to FTTP, but my old copper phone cable from the BT pole is still in place and has been joined by a fibre cable. I intend to keep my old phone number and use a voip service from A&A or Voipfone, but I understand that I must not attempt to contract this service until the migration is complete and the phone number is in limbo or I may inadvertently terminate my new broadband service.

My question is, how do I know when the migration is complete? My broadband service is working on the new fibre connection, and my old phone service provided on the copper BT cable is still working 2 days after the fibre installation - there is still a dial tone, and I can successfully dial my number from my mobile!

Can I contract for my voip service now, or do I need to wait until the old phone service stops working??|

That sounds surprising, mine ended the same afternoon the ONT was commissioned - perhaps they have forgotten you?

I'd suggest it is complete when you can no longer dial your landline phone. Or when 17070 indicates a different number on your landline to yours. My phone line continued 'working' electrically for about a month after that.

Thanks @pvmb for your very speedy reply. I didn't know about the 17070 test service and I have just tried it - still my old number!

I did wonder if part of the problem is that the fibre installation was done in 2 separate visits. The ONT and fibe connection to the external junction box was installed last Friday, and the new cable from the pole to the junction box was installed this Monday (by a different engineer).

I'd be interested to know how you got on with this as I am about to have the very same situation.

One point with my setup is the phone service is directly from BT with FTTC provided by Plusnet - this was back from the days where Plusnet would provide service on a line where they did not provide the voice service.

I'm still waiting to find out whether my transition to FTTP is complete! The fibre installation took place on 2 days, Friday 19/6 (internal) and Monday 22/6 (external fibre cable). The broadband fibre connection worked from the afternoon of Monday 22/6, and the landline phone service on the old copper cable is still working. I logged a call with Plusnet reporting this situation, and I apparently need a visit from Openreach to complete the order!? I have no idea why this is necessary - surely they can test the fibre connection remotely to confirm that it is operational. This visit is scheduled for next Friday 24/7, but has already been postponed once from 15/7.

As my phone number is still working, I can only assume that the number has not yet been suspended and that I will still have 30 days to reclaim it when that happens.

I will post an update when (if?) this odyssey is finally complete.

Interesting that it should be so involved just to close the work out.

Out of interest was your phone service also with Plusnet?

@davec13 Is the router plugged into the phone master socket or the ONT?

Re: How do I know when change from FTTC to FTTP is complete?

davec13 — Sun, 19 Jul 2026 12:28:17 GMT

Phone service is from Plusnet and router is plugged into ONT.

Something seems wrong tthere, @davec13 - if the router is plugged into the ONT and working, the master socket and associated services should be disabled - you cannot have both working together.

Re: How do I know when change from FTTC to FTTP is complete?

davec13 — Sun, 19 Jul 2026 12:53:41 GMT

Apparently you can! The phone is plugged into the BT master socket - there is no connection to the VDSL data socket. The Hub 2 router is plugged into the ONT. Both phone and router are working.

That sounds a little strange, to put it mildly.

@Dan_the_Van / @Townman / @MisterW - any comments? 😕

"That sounds a little strange, to put it mildly."

As I said previously, he has been overlooked - someone has forgotten to do something? Assuming the landline IS still on the original phone number.

In my case the phone line continued 'working' for about a month after FF commissioned, but on a dummy, non account related exchange number. So no dial in and no dial out to chargeable numbers. Then it went completely dead.

The operative word there being 'should' . It looks like the WLR service hasn't been ceased. The completion of the FTTP order should automatically trigger the cease order on the WLR.

However, this

probably means that the FTTP order hasn't formally completed for some reason (even though its working!) and so not triggered the WLR cease.

Just to confirm, the landline is still working correctly and we can make and receive calls. The line test call referred to earlier in this thread returns the correct number..

You normally have 30 days from a cease to keep a number.

I would speak to aaisp pronto - instead of waiting for the line to go dead and also your number

Looking at this the other way, you have a working full fibre broadband service and want to migrate your landline number from the copper line (which it is still active on) to VoIP.

I would ignore the strange fact that the landline is still live on the copper and start the landline migtration.

It doesn't seem likely that porting the (copper) lindline will impact the full fibre broadband service.

RealAleMadrid — Mon, 20 Jul 2026 10:40:22 GMT

@markhawkin As something has gone wrong with this FTTP order, in that the existing PSTN service has not been ceased I would be extremely cautious and not proceed with the phone number migration until the line is ceased.

I believe porting the number in the current state could result in the Plusnet Broadband account being cancelled, including the FTTP connection.

@davec13 Have you contacted customer support for any clue as to what has happened, as you already have a working FTTP service the further visit from Openreach makes no sense at all.🤔

SixCopperKs — Mon, 20 Jul 2026 10:47:57 GMT

As the FTTP was apparently completed and working four weeks ago (!) this would make me nervous. But if the landline number is still working and ringing and making calls on the old copper line, then it certainly feels like the landline number is not in immediate danger of being orphaned and lost to the 30-day limit. It’s still charging its calls somewhere!

Personally, I’d talk to PlusNet tech support right away to get a confirmation that the new broadband-only contract is working as far as PlusNet can see. And maybe see if Friday’s forthcoming Openreach appointment for the OP will finally wrap up loose ends.

But I would agree with you @markhawkin that getting on with migrating the number should not affect anything. Perhaps, at worst, it will cancel a service that PlusNet already thinks it’s closed.

My experience with AAISP was that when I triggered a migration, their supplier still took a few days to complete the move on to A&A’s systems but did it promptly on the date they chose. I think I would push for migration after talking to PlusNet about the current contract.

@RealAleMadrid

You could be right but reactivation of a working FTTP connection SHOULD be reasonably simple.

My greatest concern at this point would be saving the landline number hence the suggestion of starting the port.

Re: How do I know when change from FTTC to FTTP is complete?

MisterW — Mon, 20 Jul 2026 11:21:15 GMT

I'm with @RealAleMadrid here, the FTTP order clearly hasn't fully completed. As such, the Plusnet account will still be linked to the previous FTTC service. Attempting to port the phone number will very likely close the Plusnet account.

Yes, restarting the FTTP service shouldn't normally take very long , but with it currently in this 'limbo' state , I wouldn't be so sure. In any case it would need a new Plusnet account.
