Caller display units

Hi
I have a caller display 1000 unit, taking the back cover off ready to change batteries, several jumped out and as a consequence, having replaced batteries It no longer shows a display ??/
Any suggetsions please ?
ALSO Does anyone sell caller display units anymore ? BT seem to have discontinued everything ?

Loads on Ebay but make sure the battery contacts are clean in the right way round and note some batteries seem to have a longer outer case than they used to have and make good contact hard,
If any post helps tick the star box on the left
Just cause Im paranoid dont mean they are not out to get me

Caller display only works on some calls

I have a paragon 650 on a bt anytime call plan.
I have only one socket and only the telephone.
When the phone rings the number will only show on some occasions. If I do a 1471 the callers number is listed.
Some times the same callers number will list and on other occasions it does not.
I have put a paragon 500 on the line with the same results(this phone works perfectly OK on another bt anytime call plan line)
any ideas
thanks

If you report it to BT, they will investigate for you. It is most likely a faulty line card in the exchange.
Provided that you report it as a caller display problem, they will arrange for an engineer who has a caller display unit, to check the line in the exchange.
It could simply be that the line gain setting is too low, as the caller display does use a burst of signalling tones, just before the first ring is sent. If you are a long distance from the exchange, then this signal may be too weak.
If this burst is not received properly by your phone, then so number will be displayed.

BT Call Reminder Display Units Clashing ( BT260690...

Hi there. At last i have been able to post this message !! I have recently signed up for the Caller Display service but not the 1571 (i have an ansaphone). I then bought two Display units (Code. BT 260690 ) from the internet.
If i connect 1 unit to 1 phone it works fine with an occasional check for messages after the phone has been used, but if i connect the 2nd unit to a 2nd phone BOTH units are frequently checking for messages and while this is happening my phone line is engaged.
I have spoken to the BT Help Techs and they tell me that i should be able to use multiple units without a problem. However their only suggestion was to fit a Filter on the 2nd phone (which made no difference).
My Broadband is connected to an ADSL V10 Master Socket which does away with the need for seperate filters on the phones.
My system had the new master socket fitted about 6 months ago and the wireing was checked then so there should not be a problem with my set up. BT has offered to send an Engineer at my expence but i thought it might be worth trying the Forum to see if anyone has had a similar problem and may be a solution.
Thanks.
Dave.

Hi. Thanks for your reply.
No i am now back relying on my ADSL V10 Master socket with it's built in filter. Should not require any other filters on the setup. Dave.

Old caller display CD1500

I have an old BT CD1500 unit which has inch high numbers and letters and includes a 70 number directory of names which displays instead of the number, a brilliant bit of kit, mine has been working for many years on an ordinary line, then later with BT Broadband.
I just had BT infinity fibre broadband installed, and the last call displayed was the Openreach Engineer to say he was on the way. The engineer did not check to see it was working before he left as he should have done.
When the CD stopped indicating new calls I rang to complain, but when we realised that the caller id on my cordless phone was still working Openreach told me the CD1500 was obsolete and there was nothing they could do. The CD1500 still showed the time correctly and indicated when the line was busy as normal, just no incoming calls indicated. Very suspicious that the equipment was working perfectly until the engineers came! After some research I uncovered the following vitally useful information.
Early BT caller display equipment usually will NOT work on Cable phone lines as they use a different signalling standard, later equipment is mostly dual standard, but you do need to check before switching providers. Mind you most sales people BT or cable company have no idea of this.
The thing that brought my CD1500 back to life was when I discovered that the unit is polarity conscious. For most modern phone equipment it does not matter which way round the incoming pairs of the phone line are connected although this used not to be true, old BT pay hones and the now obsolete party lines were dependant on the line pair being connected the right way round, but not any longer.As a result most Openreach engineers are lax about ensuring that lines are connected with correct polarity, and this does not usually matter, but it does matter with early caller display equipment like the CD1500.
This was easily fixed and hey presto incoming calls are now displayed as before.
Of course only Openreach engineers are allowed to mess with the line in this way, so unless you are absolutely sure you know what to do then don't, because you won't want to pay Openreach' wickedly exorbitant call out fees to fix any problems you may encounter. They should however agree to send someone out free of charge to swap the wires as they caused the problem in the first case, but you do need to be sure this is the cause of the problem first. It is scandalous that you may be expected to agree to pay to find out if the problem is something as simple and preventable as this.
So if you have elderly BT caller display gear that suddenly stops working especially after engineering attention to your line then the polarity may be the reason.

The CD 1500 is not compatible with broadband, due to the fact that the filters in the equipment, cannot pass the correct signalling conditions. This has been known about since broadband was first implemented. I had a CD 1500, which stopped working when I got broadband, a long time ago.
If you need a stand-alone caller display, then all of the new models will cope with the DTMF data burst which is transmitted along the line, before the first burst of ringing current.

Caller display partial failure again

On 3 April 2014 I reported that my caller id had not been working since 24 March 2014 (last incoming number displayed on my phone).
After checks I realised that caller display did work on an ordinary directly connected handset but not on my Siemens Gigaset S795 cordless/answerphone system. I assumed it was faulty and bought a new base station which also failed to work.
On 23 ‎April ‎2014 I reopened the fault . As reported the system had worked perfectly for years before this. *#234# confirms CLID is active.
The new unit still does not work even when connected directly to the master socket with baseplate removed (i.e. no other phones or broadband filters connected).
However, the new phone works perfectly when connected to my next door neighbour's phone line.
Incoming calls just display 'external' but otherwise I can make and receive calls normally. My broadband is unaffected.
I have to assume that something has changed in the quality or strength of the incoming caller display signal.
Would you please look into this since when I checked the progress of the last reoprt earlier it was marked as sorted before I reactivated it suggest any further steps I may take to resolve this matter.

How can I connect my MBA 11" 2012 to my Imac 21.5" mid 2010 as a display unit. Connected using a mini display port cable and this did not work. Any guidance welcome. Thanks. John

I bought a belkin mini display unit cable( new) and connected the thunderbolt port in the MBA ( 11" , mid 2012) to the Imac mini display unit port using this cable. Pressed the CMD & F2 keys on the Imac keyboard as required but this did not work. Should I try with another cable ? Should i try with a thunderbolt cable ( recommended by appple support ) -- but they too were not sure about this. Is the Mid 2010 21.5" Imac not able to function as an display unit? Any guidance would help and will be much appreciated.

Welcome to Apple Support Communities
Only the 27-inch iMac and Mid 2011 and newer iMacs can be used as an external screen, so you can't use your Mac as an external screen. See > http://support.apple.com/kb/PH11302

Registering for Caller Display. Do I need to?

Quick history:
Mod on this forum arranges new deal for me for combined Infinity/Call package.
I agree to new deal on condition that I get everything on my account as it was.
New contract starts (Broadband/Calls/Line Rental) on 10th of September 2013.
My Call Package includes BT Privacy, etc. at no extra cost. See pic below...
A few days later news breaks that BT intend to start charging for the same calling features.
I write to the Mod asking if I will have to start paying the fee for these services. He doesn't reply. Eventually I get a reply (obviously automated) telling me the info is on the website, and links to same.
I write back asking for a proper reply to my question; this time I get a reply from 'Yunus', but it doesn't answer the question, (he only confirms that line rental will go up 6.4%), so I try other means.
I use the price increase checker linked to on the other thread here; it tells me the Infinity/Calls Package will go up, but there is no mention of any changes to my Calling Features prices.
I try Live Chat; holy sh!t, these people are useless! Are they paid to just tell you want to hear?
First guy tells me 'no increase' in any of my prices';
second guy says line rental going up, Infinity going up, but caller features package will not go up as they were included free in the package I signed up for with the Mod here
third, it's a girl; she says everything will go up, and if I choose to leave I need to pay a full year's charges for cancelling.
Plainly, they are not all correct.
All I want to know is, what is going up? When? Do I have to sign up/pre-register for this free year's Caller Display thing? Won't that mean my contracts for BB/Calls, and Line Rental will have different end dates?
I have read the big long thread about the rises, so do not require a repeat of the answers given there as most of them contradict each other anyway, just like Live Chat.
It would be helpful to get a reply from a Mod (preferably the one who signed me up to this new contract in the first place) and not from any of the BT 'groupies'.
Thanks.
Incidentally, I've not had any letter or e-mail informing me of the price rises at all.

Been there, done that!
Also spoke to Live Chat - pretty useless!
My questions were:
What else will go up?
Will I start being charged for caller display, etc. when they are clearly included free as part of the package I agreed to sign up for with your colleague?
Do I have to sign up/pre-register to get it for free when BT do start charging?
Will this mean my Line Rental and BB/Calls contracts will have different end dates?

Caller display not worked since June 2014

On 26/06/14 I reported a fault (VOL-**********) that the caller display function had stopped working following a thunderstorm in the area. According to the fault status this fault is showing as being corrected and closed on 02/07/14 when in fact the fault still exists. I tested the line using the BT test socket with a new BT2000 phone and this displayed ‘incoming call’ therefore my internal wiring is not part of the problem. I have also dialled the test code *#234# to check if the caller display service is available and confirmed that it is. I then tested the new BT2000 phone on the neighbour’s telephone line and this showed the caller ID for incoming calls, as did my other telephone as well; therefore none of the telephone handsets are at fault. Three times BT have informed me that the fault has been fixed and yet I still have no caller display. Reading through the forums it would appear that other people have encountered similar issues and that the problem is at the exchange, “An Openreach engineer discovered that the RS232 burst transferring the CLI number up the line was too weak and he then went down to the exchange to investigate. He then discovered that the fault lay in the ADSL device which lies between the analogue exchange equipment and the outgoing line”.
I’m surprised to see that BT are taking so long to trace a fault in their system last raised 5/8/2014 (VOL012-**********) and that they haven’t sent an engineer to the property or to the exchange to check the problem.
My patience is wearing thin over this problem with my Caller Display not working as it started in mid June. I’m also becoming less enthusiastic about BT and find it harder to recommend them to others.
My last message from BT, tells me that it should be back to normal on the 8 August. However, it is still not working. Their message that my phone should be back to normal now and if it isn’t report this to BT, is ridiculous. If an engineer had investigated what was causing the fault and found it, then he would have fixed it. However, either an engineer has not investigated the fault or BT is not competent in fixing their own service faults and makes these statements with crossed fingers?

An engineer called yesterday and told me that he had been asked to test the line for a voice fault not a Caller Display fault. However, his testing revealed there is no line fault, CLI signal is strong and he was happy that the new BT2000 phone (bought after the lightning strike) is working properly. (This phone had also been tested on a neighbour’s phone line where it displayed the callers number). He also found that this same BT2000 phone on my line was not displaying the Caller’s number (CLI), but couldn’t offer any reason why.
I conjectured with him that these tests must bring the problem down to a corrupted CLI signal which does not allow the phone to understand the phone number being sent.
When the lightning struck the phone line back in June, it blew the telephone connection in the back of the Sky Box with a flash and bang (telephone cable now removed from the Sky box). It shorted the Openreach Faceplate (now replaced) so that the phones and broadband stopped working and it caused the phone to light up and react as it does when a call comes through.
Now isn’t it possible that the lightning also travelled along the copper wire to the green cabinet just outside the house and damaged something there which is corrupting the CLI signal, but which does not not show up when the voice line is tested? If not, then there must be a problem further back in the infrastructure, possibly in the Exchange, that is causing a corrupted signal to be sent to my phone?
He told me that another team would have to investigate the Caller Display fault as he was instructed to look into a voice issue and as a field engineer he was not able to investigate any problem that might be in the Exchange. I don’t know whether this Exchange Team would be able to investigate a problem in the Cabinet if nothing is found in the Exchange or can that only be done by a field engineer? He told me to contact BT again as he’d done all that he had been instructed to do and they would have to instigate a fault team to further investigate the problem.
When all this is considered we have the basic problem that BT are unable to provide me with a Privacy and Caller Display Service that I have been paying for, because of a fault in their infrastructure. How much longer is it going to take before they correct the problem that’s been going on since June 2014?

Caller display won't work since i've swooped to BT

I have a PANASONIC cordless trio phone set, caller display worked fine untill we swooped to BT Broardband and Phone package. I have checked the phone line without the filter still no display can anyone help.
Solved!
Go to Solution.

Hi Cobra,
It is possible the caller display facility hasn't followed you across from your previous service providor.
You can check this by dialling *#234# this will tell you if the service is active (caller identity will be displayed) or not (caller identity will not be displayed).
If not active try dialling *234# to activate, if the message says 'this service is not available' (or something along these lines) the the facitliy is not rented on your account and you will have to call BT to arrange or log on to BT.com to order through the net.
The fault teams on 0800800151 can order this or you can call the sales teams directly on 0800800150.
hope that clears it up for you :-)

Another Caller Display Problem

My caller display stopped working today at 14.00hrs and dispite reporting it several times and getting a text saying its now fixed, its not working.
I have no filters and a filtered face plate, on infinity broadband and tried 2 new bt phones and they both display the same as the old ones NO Caller ID is Displayed.
I took my old phones to a mmate and they both show caller display, so sispect its another one of those weak signal faults ?
Can a mod here take a look at it for me ringing India is winding me up
Solved!
Go to Solution.

No filters as I put in my first post a filtered face plate.
The phone is plugged into it direct, but it started working again on its own dispite a call from India saying problem is with my equiptment! which its not.
BT are a shambles and its ok when everything works and I'm lucky mine never turned into a 6/8 multi call to 151 like others here.
What caused it to stop working ? thery dont know, how it got fixed they dont know, other than to say after it started working again the faults in my property.

Caller Display no longer working

I have had Caller Display since our exchange was updated to System X - must be 20 years (it used to be called CLI when I worked for BT) and it has always worked perfectly.
A few weeks ago, it stopped working and seems to be beyond BT's capability to fix it. I have scanned the forum and have tried everything suggested but nothing seems to make any difference.
I have a separate 50 number caller display, which I had from the beginning and a modern BT Hudson cordless phone. The caller display doesn't register and the phones just say 'external call'. Dialling *#234# gives announcement 'callers identity will be displayed'.
I have tried connecting the display and a different phone, directly to the NTE, under the faceplate, and using different makes of filter.
BT have made several attempts to reset the facility and have taken it out of service and reinstated it. Nothing has made any difference, although on one occasion a couple of numbers did briefly display and then it stopped working again.
Finally, I got cross and insisted that they sent engineer to sort it. When he arrived, he had no idea what to do about it and said that he wouid hand it back to the exchange. Later that day I received a text to say it was fixed but it wasn't.
After all this I began to wonder whether both my devices had coincidentially gone faulty together, so yesterday I took the display to a friends house where it worked perfectly!
I have reported the fault again but have no confidence that it will be rectified. If anyone has anything else I could try I would be most grateful. CLI is a really useful facility and I miss it greatly!
Maybe the only solution is to go to Virgin which, as a loyal BT person, I would hate to do?

Martin Hi
It does sound that you have done all the relevent tests to prove where the fault is.
I assume you have tried it without a Home Hub / Router connected? I have known these to mask the CLI.

Full screen incoming caller display 2730 classic

Is there a way of making the phone display the incoming caller display larger, when your driving and using Bluetooth its almost imposable to read the number or name of caller
I know the font size can be changed for other applications but this one is a must as it could be quit dangerous to try and read who is calling when driving
A full screen would be better

Is there a basic nokia phone that just makes and receives calls, text, and with Bluetooth with extra large fonts so the phone can be read, mostly for incoming calls
My 10 year old 6310i was good but the bluetooth let it down

Caller Display Problems

Hello, I recently rejoined BT for home telephone and broadband having been with talk talk and O2. I have had a bit of a mare with the Infinity and phone install but it is done now. I have contacted BT about caller display that was included with my package. They stated it would be active on Monday 27th Feb. It was not. Contacted them again and they said it would be active on 28th. It was not and again, I contacted them yesterday and despite assurances caller display is still not active.
I have done the *#234# test which says caller ID will be displayed. I have some rather expensive Gigaset SL78H digital handsets. Caller display worked with O2 and Talk Talk but it will not work with BT. Is this handset compatible with the caller display servie provided by BT? It worked with my previous phone line providers.
The phone is plugged into the master socket via a network. I have removed the ADSL filters as I was advised to do but to no avail. I am at my wits end now.
Thank You for any help.
Neil

I have just joined this forum out of sheer frustration at our Caller Display still not working after almost three weeks, numerous phone calls, online chats etc., from advisors insisting it would be up and running again in 12/24 hours or whatever. Yesterday, someone even said I should go and buy a new phone! to try out the equipment again before they send out an engineer. Bought a new phone, keyed in some numbers, got them to phone the land line and it still came up Unavailable. I even took a phone call from BT on the new phone so it proves that the new one works. All the phone calls I have had with BT advisors have been from people overseas I think, and I don't think they can grasp the fact that the Caller Privacy ID is still on i.e. our landline number does not come up on other people's phones and all our directory entries are listed in our phone and we can use them to dial out. Dialling out and receiving phone calls is still ok. They are now saying an engineer will have to come out but I know for a fact it is nothing to do with our phone itself. I don't want a bill of £130.00 if he finds nothing wrong with it. I am at the end of my tether.
All this would have been avoided I think if we still had BT shops in the local high street.
Any ideas anyone?

Caller Display/BT Answer 1571 charges

Unbeknownst to me, Caller Display and BT Answer 1571 have been free since 2005 yet BT have been charging me £3.50/month (slighlty less before price increases) so I have been paying unnessarily for 9 years! I queried this with them and they said £1.75 of it was for BT Answer 1571 which I don't recall ever signing up to and does not appear anywhere on my bill. All that appears on my bill is £3.50 for Caller Display. How was I supposed to know I had 1571 and had been paying for it?!?
It is a really deceitful way of getting money out of their customers because I presumably didn't specifically tell them I would now like it free instead of paying for it.
I signed up to Caller Display about 17 years ago when it was chargeble but would have expected them to drop the charge in 2005 when it became free for everyone else, silly me.
BTW I have now cancelled it and signed up to BT Privacy for 12 months so am now getting it free. This doesn't help me recoup the £100's I lost though!
Hope this post at least helps someone else pick up on it.

They started charging for this service for all customers at the start of this year,
