Yes, I have read where engineers have fitted the wrong ONT then had to change it.

How do you find out which brand specific supplies the customer.

Can it be accessed by the public.?

That could be difficult even if they wanted to make it public.

An exchange can have 2 different OLT manufacturer in it providing FTTP.

A street could be connected to a Huawei OLT while the next street down on a more recent deployment could be on a Nokia OLT.
In that scenario 2 people ordering on the same day from 1 Street away would both get different ONT's.

Mmmmmm very interesting.

Hi Tim

I can read your mind you're worrying if your nearly completed FTTP infrastructure will be connected to an older ECI OLT which would prevent you from being able to order the full 1 Gbps package. Its extremely unlikely, it more likely to be Huawei or Nokia so you should be fine.

Phone duties will pass to ISP-supplied equipment. Openreach don’t want to be in the business of handling telephone calls.

Edit: Also if you look at the services available there are definite incentives to moving this into the router - just looking at BT's Digital Voice you have HD voice, the ability to make multiple calls at the same time, call rejection at a network level.

Any idea what codec they're using for DV? Otherwise it reads very much just like another hosted VoIP service.

Is it entirely possible for the fttc side to be covered huawei and the fttp head-end by nokia?

Sorry Zarjaz, i'm asking these type of questions not annoy but those ones that pop in one's head and is afraid to ask 😁

I have no idea. I know that it provides actual HD quality when calling a BT/EE mobile, and somehow manages to put an 'HD' logo on screen when I call it from my works' SIP trunk - though I would imagine this is just what happens if the call is identified as VoIP end-to-end as there are no HD codecs enabled on our SIP trunk.

I would suspect not.

Its a shame they didn't stay using the FVA port, they could of just stuck hardware at the required exchange that converts over to the required protocol they wanted.
That way they wouldn't be wasting that bit of ONT hardware.

In reply to a post by Zarjaz:

Based on the simple fact that both current ONT’s I have seen installed, the Huawei and the Nokia, no longer have FVA ports on them.

Well we are still on that port, BT have told me that they will keep us on there until the absolute very last possible moment and that they will notify me months before hand.

I am taking that as a pinch of salt due to BT have said one thing in the past and did something completely different.

TBH I am hoping by that time BT will offer more options to provide the (Digital Voice) phone service, due to I am not a fan on being forced to use their SH2.

But we have a little while yet, so it might all turn out good by then.

That could well be a possible scenario.

You know me well dect.

I'm expecting solo ata and or handset base stations to have network access (wired or wifi) to appear .. The bigger problem will be how the less techy section of joe public will be catered for

Can't find anything from BT to suggest what they use, but I expect they'll use a combination of codecs to support regular/standard bandwidth POTS using G.711u/a and probably a combo of G.722, G.729 and quite possibly Opus also for wideband codecs / "HD" voice calls.

I know for example that Sipgate use G.729 and G.726 for wideband codec support. The Cisco phone on my desk supports G.729 and G.722 amongst some others, so calls connect at "HD" using G.729 here.

BT Business already offer a pre-configured VOIP (IP) dect handset for Digital Voice, you simply plug its base station into any router to use the service - zero configuration req'd.This is the kit which BT sent me (free), I imagine their Residential sibing will also start offering something similar for those that want to use Digital Voice with their own routers:

I did ask BTB for the SIP login credentials as the Yealink handset is locked down but they weren't willing to give out this info. But not a big deal, as I can make/receive landline calls using the BT Cloud Voice app on my smartphone.
