Digital Voice where BT is not the broadband supplier

I think that I may have asked this before, but cannot find the post.

As you can see from my sig, my broadband is A&A FTTC. My home telephony is BT, currently PSTN via copper.

So what will happen when BT subscribers on our Exchange (Hawarden) are offered - certainly if with BT Broadband, Digital Voice?

Will I and other non BT Internet users be offered either an Analogue Telephone Adaptor (ATA) or a proprietary BT DV phone to use on our non BT Broadband? I assume that if this is the case, then our existing phone number will be offered on DV?

Finally, once on BT's DV can you port the number to a VoIP supplier, thus ceasing the line and the 3rd party broadband associated with it?

Thanks.

Cheers!

Beat the rush Clive, port your BT Wholesale voice number to an independent VOIP provider now … get your required telephony working as you wish …. then your future is suitably robust, whilst being flexible also.

I will be interested to see what the experts on this forum say but I can't see how BT can offer you a DV telephone service if you stay with A&A for your broadband.

As suggested, that would shut down my FTTC - with no where to plug my ATA in!

If FTTP was currently available, then I would get FTTP and then port my number to VoIP which would shut down the FTTC that I now have.

Strangely (?) When I wanted our village hall's NTE moving to the other end of the building together a first time supply of BT Broadband and changing to a Business line from the residential one that we had, whilst retaining our existing number. BT Sales said that they would do this by fitting a new dropwire and setting it up on a NEW phone number and once those jobs done would transfer us back to our original number. I certainly had my doubts, but that is exactly what they did and it all worked.

In other words, I cannot see why BT cannot simply port the phone number without ceasing the line and at same time renumber the line retaining the FTTC. But.......

Cheers!

So long as they could supply either an ATA or digital desk phone which has whatever algorithm their DV requires, I can't see why there should be a problem.

Something in the back of my mind is telling me that BT have different DV solutions for BT Residential lines and BT Business lines. But quite why, I don't know.

To me the difficulty in doing what I and I expect many others want to do, seems to be done to customer retention for voice services?

Cheers!

I thought it ceased a bundled service which I am guessing you don't have.

Maybe you need to call BT to find out what happens in your scenario

The issue is that when DSL services were introduced BT (now the Openreach part) used the telephone number to identify the circuit. Changing the telephone number breaks the association between the number and physical circuit causing the DSL service to be ceased. AFAIK there are process routes to avoid this but it isn't easy, especially if POTS and DSL are from different providers.

Is your A&A FTTC on the same copper line as the POTS service? I know that A&A offered DSL-only long before SOGEA.

If you have one line with both services then you could migrate to A&A VoIP as they have worked out how to poke the Openreach API to migrate the voice service out without loosing broadband, but they only offer it if using their services.

If you have two lines then the BT POTS would be migrated to FTTC (assuming WLR switchoff happens before FTTP becomes available), possibly the 0.5M/0.5M service, and a SH2 provided to act as modem and ATA.

BT Business have at least three different IP voice products, all different from BT Residential Digital Voice.

Probably best to talk to AAISP directly, but what you want to do is available to order as long as you take their VOIP service.
See this page specifically about the subject. It includes:

Many people see using a copper pair (AKA phone line) for actual telephony as somewhat antiquated and would like to move the copper pair to us for broadband but move their number to Voice over IP. Normally moving a number to VoIP kills the phone line and broadband, but we can do this without a break in service. This is called renumber and export.

We can port in numbers without the loss of the broadband and the copper pair service only if the broadband and copper pair are provided by us.
...
...
You have broadband and the copper pair from us already

In this case, please contact sales who can progress the renumber and port manually.
...
...
You have broadband from us already but we don't provide the phone line

In this case we will take over the phone line service and will port the number to our VoIP service.

That final option (on the right hand side of the page as you scroll down) looks to me the way to go .

If there’s no available FTTP in the equation then your FTTC service will become a SOGEA service with voice running ‘over the top’. The question then is who is the provider of that basic SOGEA service…

This would be good to get clarified, but my understanding is that the provider of the actual line (in your case BT) is recognised by Openreach as your “CP” and they would be responsible, by default, for moving you off PSTN (to their DV service). They would end up taking over your broadband provision too.

However your broadband provider (in your case A&A) could also take the lead and migrate you. As per pluralist post, this would need you to instigate for them to take over your voice line provision.

Early days, but like pluralist advice, I’d check with A&A on the details of the process, to make sure there’s no surprises.
