Perhaps more seriously, there is also a risk that the phone number will be lost between the voice service being ceased by BT, and it being "ported" by IDNet (it isn't really being ported, because by that stage it will already be terminated)

If this matters to you, then stop the FTTP line migration *now*. Get IDNet to do a same day port of both data and voice: or much better, migrate the voice to a standalone VOIP provider, and you'll never have to deal with this problem again in the future.

Doing it this way has the opposite risk: you may be without FTTP service for a number of days, between the VOIP port-out (which could terminate the BT FTTP service) and IDNet reactivating the line.

I say "could" because BT *do* supply data-only FTTP as a service, so it's *possible* that porting out the phone number will leave the FTTP data running - but I wouldn't bet on it.

Seems to me like the OP knew what they were letting themselves in for though....

Just IDnet being clueless.

I knew there could be issues - I've had a good read online before committing!

I'm not going to put this wholly on IDNet - There comms has been much better than any mainstream company throughout!

After a quick phone call with them i had hardware shipped next day and i am up and running with a temporary number!

If they had quoted me 16th for FTTP and 28th for VOIP I would have told them to get stuffed.

these were sent in two separate emails - given a good length of time apart - i assumed both FTTP and Phone would have transferred on the same day!

Thanks for the replies - In the end the FTTP transferred seamlessly and i have a working phone - I'm just waiting for the number to port over!

Had a similar problem about a year ago. There was no easy way to port my existing landline number but I needed to keep it for continuity of contact with several people as it was the only number they had. It was a bit convoluted, but there was way a with BT of porting my phone number to a VOIP provider and keep my Fibre connection. As has been said, if you terminate the phone number as a way of porting,, the whole account is terminated including the data connection and then the chances of keeping your original phone number are drastically diminished. So the only solution to secure retention of my existing landline number was to port my number to a VOIP provider (Sipgate) and then on the day of transfer, having been notified that the number had been ported and checked on my mobile by calling it, I re-signed with BT on a Data only deal. The old connection kept active for about a week and then stopped. I had made arrangements to use a temporary Internet connection at home using a Dlink SIM modem which kept us going until BT reconnected on the new contract. Not sure why it took 2 weeks to re-connect a working Data connection - there was no re-wiring or any work required to make the connection just exchange and billing switching. Anyway, the outcome was I retained my landline number with a degree of certainty I would keep the same number. It just seems to make a straightforward job very difficult rather than just port the number and keep the Data connect on a Broadband only deal. It certainly isn't cheaper on the Broadband only deal.

Did they manage to reclaim your original number in the end?
