Just sharing our story with EE/BT so far:
I moved my mum from a working PSTN/FTTC Plus.net connection over to the new fiber connectivity. We started the process in January but Openreach failed to turn up twice and then turned up at a bad time unannounced. Eventually we got there in May.
The setup inside the house seemed to go fairly smoothly. It wasn't until a few days after we realised that Calling Line Identity wasn't working.
The setup: A BT Paragon 500 phone into the back of the EE Smarthub Plus 7 (physically to the BT socket on the hub). A BT 4500 DECT base unit connected via an EE supplied Wifi adapter, with 3 hand units.
We noticed that 9/10 incoming calls would just show as "incoming call", no number. But, just occasionally the number will show, so it's not 100% failure.
Outgoing calls seem to work just fine, and incoming audio calls work, most of the time. However I have seen where I answered the call on one dect phone, and the other phones kept ringing. The main issue though is the CLI.
I'm exhausted talking to BT. I've spent hours on the phone with them repeating the same tests, the same arguments. At least 6 calls now, usually 1-2 hours per call. It takes that long to finally be put through to "New IT Tech".. who then go to a team called the "offline team", who you can't talk to at all and don't listen to the facts.
We've reset the hub, we've factory rebooted it, they've taken CLI features off of the account and added them back on.
During all of this, the support people have told me privately that the new Digital Phone system has multiple issues, in its management systems and in the backend of it. One even offered to cancel our contract and move us to an "older" system, which would mean replacing the hub and changing contract.. but all to get away from the "new system".
Yesterday, despite telling me there's nothing wrong with the hub - they're now sending me a new hub. Except, I don't live there and so its a 400 mile round trip to go an replace/setup a hub, that probably won't fix their issue.
And the repeated claim from some of the support teams: "It's your phones... they're too old". Weird, because up until the move, both phones worked perfectly fine on PSTN CLI. I've has some of the engineerings agree with me that it's not the phones, but some insist it absolutely is. And they really don't like when I argue back that, even if it IS the phones, these are BT phones, working to standards that BT implemented, and claims to support in Digitial Phone.
I've now hit a wall with BT support. if the new hub doesn't fix the issue, I don't know where this goes.
What's interesting.. one of the engineers, kindly, sent us a Battery backup, and in that package is a wifi-based phone. And, on that, the CLI shows correctly for every incoming call at the same time the other phones don't. So if that phone can show it, but the phones working via adapters/plugging into the back don't, to me, that would indiciate the issue is with the hub, or more directly, the hub software. That also helps confirm that it's not an EE/BT network issue, as the CLI must be getting to the hub for the wifi phone to work.
But the BT Support engineers are adament that the hub software is bug free and works 100% of the time.
They also insist that I'll have to replace the phones, at our own cost, never mind the fact that the phones work fine and it seems clear it's the new system at fault. They actually argued with me yesterday that both phones, two different models must of failed, at exactly the same time, with exactly the same CLI symptom, coincidentially at the same time as we moved to the new hub and setup.. it couldn't possibly be the fault of the hub. I'm flabergasted bt that response and conclusion, with no evidence to support it. We ended up ending the call as both I and the support agent weren't getting anywhere and they kept insisting they couldn't do any more (perhaps pass up to the team that the hub has a bug?)
I guess I now have to wait and see for when the new hub arrives and test with that, and try to find a friend/neighbour still with a PSTN connection so I can prove the old phones work just fine.
I'm bitterly disappointed with the whole experince so far.
For the forum: If anyone knows if there's a list of what phones are/not supported, that'd be useful. We were told originally that 99.9% of all phones will work just fine.

@adrianmarsh Is it not possible for you to use the BT4500 big button phones connected to the DECT side on the EE 7 Plus hub for the call's and then the Voicemail side taken care with the Base on the DVA, is there a listen play feature or does it need a handset to listen for the left message?
Sounds like that would be the best scenario but may just be a little confusing operational wise, wonder if a standalone digital voice recorder that has listen to play with a speaker in it is an option. Boy are those expensive to get as a standalone unit, have linked a unit below not sure if anything on the DVA / EE Hub ATA interface is going to be a 100% get through every time you would just have to try see.

What are you calling DECT side? Is it an DECT ATA remote from the router or the DECT base station incorporated in the router?
BT4500 handsets connect by DECT to their DECT base station which in turn is wired into back of router or to a remote ATA. The BT4500 base station itself has its own handset as well its own ability to play its own VMs. No need any fancy voice recorders.

@XRaySpeX The BT4500 phone capable off GAP was connected direct to the EE Hub internal Dect base bypassing the phones own base station. That was also done by a user in a previous post, but the downside the RAW BT4500 does NOT have all the features needed.

@JimM11 : That's fine! A DECT slave handset may switch between bases at its will.

@adrianmarsh You don't happen to have an old ADSL filter lying around, would be worth trying it in between the output off the Hub or the DVA and the BT4500 Base station.

Consider the possibility that the problem lies with the cable connecting the router to your DECT base.
Try re-seating the plug in its socket under the base, or, if you have got one, try a different cable.
It's unlikely that the age of your phone is the problem. I've got a similar setup to yours with a 25-year-old BT DECT phone base and three handsets that work as they should.

@Jones01 That is what @adrianmarsh is trying to find out a system that connects via the ATA on either the Hub or the DVA and consistently display's the CLI too the phones connected, just now the BT4500 with Answering machine is just not cutting the mustard, has tested both the Hub ATA, the DVA ATA and was all working fine phone wise connected to the OR Master socket on the PSTN direct connection before his move to DV. The Digital Phone that EE has given him is showing 100% off the time the Number displayed but the BT4500 is not.
Is A&A still supplying your voice?

@adrianmarsh You mention two types off phones the Paragon 500 and the BT4500, they both appear to support CLI on them is one better than the other or equally struggle/don't display the calling number when incomming?

XraySpex,
If that were 100% true - I shouldn't be having any problem with the BT4500 bought in 2015 and a Paragon 500, much older).
Okay - so its a DECT converter.. but it doesn't seem to be the issue - its the same result if the BT4500 base is plumbed into the BT port on the EE hub.. CLI randomly and mostly fails.
What I'm looking for now, is a phone matching my mums needs, thats "Digital Phone" confirmed. The research I've found so far only seems to point to two BT models.. the Essential and the Premium. However, even on the tech specs page it's not clear if they work 100% with Digital Phone... so I'm wondering if folks here have known-working models I could look up.
Thanks!

@adrianmarsh You mentioned earlier in the post EE had a list off what was recommended, did you get that from them?
