BT Caller Display 30 not showing caller-id after Digital Voice upgrade

Taffia — Mon, 02 Dec 2024 18:09:02 GMT

Just been switched to Digital Voice and my Caller Display 30 (Yes I know it is a bit ancient) no longer shows the callers number. Shows nothing at all. I rely on it !!!.

It is plugged into the green phone port of the Smart Hub 2 and a not quite so ancient BT relate 80 phone is plugged into the Caller Display 30.

When I phone my home number from my mobile (on the ASDA/Vodaphone network) my home phone rings but no caller id shows. The same happens if I dial 17070 and choose option 1.

Do I need to do something to enable Called Id in MyBt ?. If so what ?. I cannot see any Caller Id options in MyBt.

PS I always thought that any existing internal extension wiring would still work if it is simply disconnected from the BT master socket and merely connected to the Smart Hub 2 Green phone socket but the Openreach engineer was adamant that only a single analogue phone could be plugged into the green analogue port. Which answer is correct ?

There should be a Digital Voice section under MyBT > Your Products & Caller Display should be in there. If it shows as already enabled, disable it & log off for a few minutes. Then log back on & re-enable it.

All I can see is Call Protect, Call Barring, Voicemail essentials and Call Barring, and the last two show [add now] the other two show [manage]

Nothing else.

I have since discovered that despite having enabled automatically previously, with Digital Voice it is now necessary to order it (even though it is free !!!) and wait 24 hours to get it back.

Utterly wierd requirement.

Are you sure you're looking in Digital Voice & not the old Landline?

I think you may find that the BT Caller Display 30 is incompatible with the current phone network, in fact it did not work on certain exchange types.

I think it may have to do with it needing a line polarity change, prior to the incoming CLI data burst, whereas the modern phones simply look for the data stream, which is sent just before the first ring. That allows blocking phones to supress any ringing if the number is blocked.

The line polarity reversal is a hangover from the old Strowger mechanical exchanges, and was replicated on crossbar and electronic exchanges.

BT Digital Voice does not have this feature, as its no longer needed.

Well, having 'ordered' caller-id (in order to get it back), I can now confirm that my ancient Caller Display 30 now shows the incoming number. At least, that means the ringback number from option 1 of 17070, and my ASDA mobile number now appears.

Openreach guy (NOT Kelly) spent ages rewiring my diy phone (pins 2 and 5 only) and data extensions because I had moved the previous Smart Hub 9 mtrs away from the original BT master socket and he then made up a flying lead plugged into the Smart hub 2 green socket that goes into the back of the new NTE 5C at its new remote location next to the Hub and then re-used the cat5e that I had used to extend the data from the original master socket to take the output from the Green Socket back to where it connects to my internal extension so that I can carry on having the caller Display 30 and BT relate 80 phone in my upstairs 3rd bedroom/office.

I assumed that the green socket could power all the original internal extensions but OR guy said no, only one phone was possible (but it drives the Caller Display 30 daisy-chained to the BT relate 80). The phone output on the new NTE 5C box does not work, so to have a downstairs phone I will apparently need a BT digital home phone that uses DECT to connect to the Smart Hub 2 (correct?). Does anyone know what make of 3rd party DECT phones that can do this and also have all the functionality of the BT digital phone.

There are no third party DECT phones that connect to the BT hub via DECT with full functionality.

The green socket will power more than one extension phone. Alternatively, you can use a Digital Voice adapter which is effectively a portable phone socket that you can plug any phone into.

All explained in the FAQ

Every time I try and reply, EDGE crashes before I get a chance to type any text !!??

From what I have read here and elsewhere, the digital voice adapter which plugs into any power socket seems to have intrinsic design flaws and is best avoided.

I always thought that the green socket could have a string of existing internal phone sockets connected to it (pins 2 & 5), but the OR guy claims that this could affect broadband speed.

Who is correct ?.

I am happy with what I now have and Caller Id now seems to be working. I just wish the lady who provisioned my Digital Voice upgrade, despite asking questions about my age and any telecare devices, had also asked me if still wanted caller-id and done it as part of the package.

Even your DV FAQ fails to mention that it may be necessary to 'order' it again, even though it is free.

I'm not entirely sure what the REN value of the green socket using, but I'm confident it will support more than one phone.

Whilst not exactly the same as multiple analogue phones, my green socket is currently supporting an analogue phone on one extension socket and a Panasonic DECT base station in another.

I think the problems with the adapters are in relation to not providing the necessary ring wire for older phones. I have no personal experience of using an adapter, but I have neighbours that do without problem.

@Taffia

I believe you can still order a DVA free of charge, so nothing to lose in trying one.

Although unless your phone has a rotary dial, the REN isn't likely to be an issue as @licquorice said.

Odd caller-id behaviour continues.

After working fine on my upstairs extension (plugged into the SH2 green socket downstairs via the OR provided flying lead) since Jan 3rd, the phone on my upstairs extension no longer rings, even though the caller-id 30 box shows the number. I tried 17070 option 1, and there is no ringing, just the 0800-xxx-xxxx number. As soon as I pick up the phone I hear "Ringback complete".

BT have sent me an EE-branded DVA but that didn't work either until I googled problems with it and quite a few people have the same problem which is fixed by plugging a microfilter into the DVA and the phone into microfilter. Now it rings but when I insert the Caller-id 30 unit between microfilter and phone it shows "Invalid" instead of the incoming number.

If the DVA is anywhere near the SH2 there is pronounced buzzing overlaid on the dialling tone.

At this point I tought I would consider getting a BT DV handset but the option to view and buy DV phones on the BT/EE website does nothing. Have they given up selling these things ?.

BT advanced digital home phone (the only one with a Caller-id display)

"Sorry this product is no longer available

We’re really sorry but we’ve sold out of this product and are unable to obtain more stock. In most cases this is usually because the manufacturer has discontinued the product. We don’t want you to miss out though so here’s some of our best selling products which are similar to what you are looking for. Take a look and you could just find the perfect item. Just a small point to note - they might not have the exact features as the product you initially wanted so please be sure to check the features before you buy."

Yesterday, just clicking on the icon to shop for DV phones did nothing. At least I got further this time.

Are there any 3rd party equivalents with all the same functionality ?

Unfortunately not, BT Digital Voice is proprietary.

Having looked at some of the one-star comments for the BT advanced digital home phone on the EE/BT website, maybe it is a good job that it is out of stock 😞

Hopefully they are rushing through development of a replacement that is an improvement.

The basic DV handset has caller display.

Correct, I have one.
As mentioned elsewhere my DECT phones connected to the hub show 2 missed calls when there is only 1.
