    What ho one and all,

    The road I live in has recently had optical fibre installed and can now be connected to every house, should they want it.

    I kinda want it but .......?

    My wife is Japanese and frequently makes calls 'home.' At the moment, we use one of the various CPS (carrier pre-selection) numbers and the calls only cost 3p per minute.

    If I sign up to FTTP, BT more of less, remove the cable and I can have VOIP, which apparently, is better. But they cannot tell me the cost per minute of calls to Japan with 'digital voice.' And I am unable to find out if the CPS number will work and offer inexpensive calls.

    I have spoken with the CPS company and they are not certain either; basically, try it and see! But if it does not work, I cannot return to copper cable.

    My question to the forum, do CPS (carrier pre-selection) numbers work with VOIP?

    Thanks and toodle pip

    Rex,

    AFAIK, copper cable is going to disappear in the not too distant future. I have VOIP and it has proven cheaper calling Switzerland on it than with the BT landline though I could not say about Japan.
  1.  
    We make all those calls for free on WhatsApp or Zoom, does that work for you? Can choose video or audio-only.

    Having fibre or copper makes no difference to your call, the CPS will be unable to tell which one you are using, and your analogue call is converted to VoIP when it gets to the cabinet in your street anyway.

    Copper cable is (sadly) not going away, they will switch to VOIP over the internet connection which they are already delivering down your copper cable, if you don't yet have a fibre connection.

    Gentlemen,

    Thanks for the comments. Not sure I even understand the nature of my question but I guess the reason that the CPS we use are so cheap for a call to Japan is that they also use VOIP to route the call.

    My in-laws in Japan are not up-to-speed with WhatsApp or Zoom (and nor do we.)

    The bigger issue is that to use anything that needs the computer, means that the receiving computer has to be on or one has to make a time for the call. That is less convenient than a phone which rings with an incoming call. So I would like to keep the phone line but certainly don't want to pay the BT charge.

    BT offer International Freedom for £8.99 per month which give 600 minutes. At the moment, we only spend around £4 per month.

    Anyone know what BTs plans are for those with copper based equipment such as phones, card machine, security alarm dialler etc. When they decommission the copper based system are they going to replace all the kit relying on it??

    Whatsapp is a (smart) phone based system and skype can also be on a phone which as it is always on will ring with an incoming call.

    Yes, the old PTSN network is due to be decommissioned then.

    Suppliers are hiding this fact behind the question "Do you have mobile phone reception in case of a power cut". If you answer yes, they automatically move you to VOIP without actually telling you that is the impact of that question.

    Posted By: philedgeAnyone know what BTs plans are for those with copper based equipment such as phones, card machine, security alarm dialler etc.
    The plan is that you and the supplier come up with a different solution. Yes, really, that is the plan...

    Major issue for personal alarms for the vulnerable. Key point is that currently, when the power goes off in your house, the PSTN phone still works. Once VOIP is in, it doesn't.

    I still have a PSTN landline, but all of my Broadband and LAN kit is on a couple of small UPSs good for about 4 hours in the event of a power cut.

    Posted By: RexI have spoken with the CPS company and they are not certain either; basically, try it and see! But if it does not work, I cannot return to copper cable.
    Well if they cannot tell you, then their business model is about to go up in smoke. I'd be persistent and not talk to a drone, but ask for a supervisor or their technical department.

    My suspicion is that it will still work.

    Once your call hits the exchange, and goes through the PSTN equipment, I am reasonably sure it is then routed by VOIP until it hits (potentially) PSTN equipment at the final exchange.

    True but it is in effect the same thing as copper will not function as it was originally intended so it is effectively no longer there.

    If you are in the situation that I am where there is fibre to the cabinet my house is connected to but this is over two miles away so fibre broadband does not work then once they switch off the copper based system a landline based internet and phone will not work. I am however classed as being connected to superfast so the Scottish Government can hit its target.

    My “landline” number is actually on a VoIP service (https://www.sipgatebasic.co.uk/) which gives me a normal local-area [¹] number which I use either from my computer or from old-fashioned telephones using an ATA (analog telephone adapter). It'd also be possible to use a dedicated VoIP telephone which makes some sense in many businesses but possibly not domestically.

    <blockquote><cite>Posted By: Rex</cite>My wife is Japanese and frequently makes calls 'home.' At the moment, we use one of the various CPS (carrier pre-selection) numbers and the calls only cost 3p per minute.</blockquote>You can do better than that: Sipgate's rate for calls to Japanese landlines is 1.9 p/min and 9.9 p/min to Japanese mobiles.

    <blockquote>The bigger issue is that to use anything that needs the computer, means that the receiving computer has to be on or one has to make a time for the call.</blockquote>Not necessarily, VoIP providers like Sipgate and Skype allow calls from a computer to normal phones.

    [¹] Could have had any area code in the country but chose to have the one covering the area where I'm renting and where I'm building.

    Posted By: borpinKey point is that currently, when the power goes off in your house, the PSTN phone still works. Once VOIP is in, it doesn't.

    My PSTN 'land line' is a normal telephone with a land line number that is connected to a box (pluged into the mains that goes to an ariel in the loft. Inside the box there is a stripped down mobile phone with its own battery connected to an ariel in the loft. With this mickey mouse system I get a land line phone that survives power cuts. The system was put in as a way to give rural properties a land line.


    Posted By: Ed DaviesThe bigger issue is that to use anything that needs the computer, means that the receiving computer has to be on or one has to make a time for the call.Not necessarily, VoIP providers like Sipgate and Skype allow calls from a computer to normal phones.

    Skype does as you say and drops on to the local network in the area of the called number so the caller gets charged at the local area rate of the called number. (AFAIK)
  5.  
    Skype etc also allow free internet calls to anywhere in the world, direct to the recipient's smartphone handset, over the recipient's home internet connection. The forthcoming change is that all 'landline' call services will be delivered in the same way, they will just be dressed up to look like they used to, with a separate handset etc.

    There is no longer any reason or justification for international calls to be charged any differently than local calls, IE free. They are just internet traffic, you don't expect to pay extra for 'international' emails or 'long distance' web pages. You already paid for these when you paid for an internet connection.

    The only reason why companies still have the nerve to charge for international calls, is that many people still seem surprisingly willing to pay up!

    Edit: we ditched our landline subscription a few years ago as we realised we don't need it and the broadband was hopelessly slow for the price. We haven't missed it at all. Now we just use the bundled call time on our mobiles, or WhatsApp etc for free calls over an unlimited 4G internet connection which is much cheaper than 'line rental'. If there were a faster internet connection available such as FTTP, we'd pay for that. If there is a power cut we can still use mobiles, charged if necessary from the car's battery.

    I'm guessing you are correct as the call to Japan only cost 3p per minute.

    "Pretty sure Rex still uses a Nokia 9110" Not correct!! now on a Samsung Galaxy J5, which is only around 7 years old!

    Thanks for the input. Don't understand most of the terminology and am fairly certain that our CPS will still work ut only time will tell.

    Given that we have two DECT phone and two regular phones plugged into wall sockets, would the regular phones still work with VOIP? Or will they need to be upgraded? Will the wall sockets still work?

    We need as many options as possible. There are quite frequent power cuts - anything from a few seconds to a few hours, regular cuts in the internet service - batteries at the mast across the valley failed again, and the newish high speed broadband line has been out of action for months after trees fell on it.
    We do have a slow MPUW (Mobile Phone to Up the Wood), but you have to search each time to find the hot spot.

    The landline phone is about the only thing that is 100% reliable (with occasional crackly moods).

    I received this from a local biz, who are alarmed:

    "Having done some research, we cannot identify a viable plan for our telephone needs when the big switch-off happens in 2025 (for more details, see https://business.bt.com/insights/digital-transformation/uk-pstn-switch-off/).
    Are we the only ones, or are there others who will have the same problem?

    Do you currently have a landline system with an ‘internal exchange’ where you can put calls through to other extensions and perhaps have several different phone numbers within the same system?
    • Landlines will stop working in 2025;
    • Mobile signal (if you have it) will only work with a single number mobile;
    • A VoIP solution such as 3CX using wireless broadband (like Cloud Wireless, if you can get it) gives really poor quality audio for voice – we have trialled it extensively and it won’t be anywhere near good enough for our needs; VoIP vendors do not recommend VoIP over wireless broadband services.
    Basically we will have to get a physical fibre broadband cable to Sheldon before the switch off.
    • The Teign Valley is not even on the OpenReach map for the 2026 fibre rollout – we are in a ‘not spot’ and can’t currently see this is going to arrive in time for a community solution (see see https://www.openreach.com/fibre-broadband/where-when-building-ultrafast-full-fibre-broadband)
    o We are however aware that fibre is present in some areas of/around Christow, but full details remain unclear.
    • Other companies are building other networks, but none approached so far have indicated any plans to be active in our area.
    • We have a quote for £20,000+ to get fibre to Sheldon (a) it is subject to survey and (b) we can’t share it with anyone else. Just FYI that cost covers a 3 year contract.
    So if you have a telephone system similar to ours, how do you think you will solve the problem for your organisation?
    Do you have different critical services to those we’ve identified that you can foresee being severely impacted or stopped altogether?

    We are probably about to go with the £20K contract given that this is a business-critical issue and some solutions can take a couple of years to implement.
    But we don’t want to go it alone if there are others in need of a solution and there is potentially one we could share.
    We are likely to sign to pursue the £20K contract at the end of February unless something unexpected turns up sooner than that.

    We have raised these concerns to our district councillor, and also at county council and MP level."
  6.  
    They sound a bit confused Tom, they seem to have been told that they will have to purchase a fibre connection to replace their copper line, which they have incorrectly been told will stop working.

    As you correctly posted a few days ago, the copper lines will keep working, just with the voice signal modulated in a different format. You could offer to put them straight, and save them £20k?



    When there's a power cut across an area, the power stays on for copper lines because there is a battery bank in the green roadside cabinet. I haven't found any info about how big those batteries are or how long they last*, they seemed to have ridden out multi-day power cuts after Storm Arwen better than the mobile network did. They will presumably be kept to power the VoIP equipment in the cabinets so I don't understand why they won't continue to energise the copper lines, perhaps the VoIP equipment draws more power. You apparently can get home VoIP routers with battery backup ups for 1h of calls, or you could plug the router into any battery ups.

    https://shop.bt.com/content/uni2/documentation/fv54/cyberpower_bbu_sh2_(2).pdf

    *Edit: some forums suggest there are 48V lead acid batteries in the base of the street cabinets giving 4h-24h of power down the copper lines, depending on usage. Some suggestions that Openreach will drive round the cabinets replacing/recharging the batteries, if the power is off for longer.

    I could be wrong so sorry if this is the case but my understanding is the in 2025 the copper system going to the cabinet will be switched off. AFAIK the only working copper after this will be from the cabinet to the property. This is fine though limited as long as you are not too far away. Once you get more than a mile or so away which is a lot more people than most are aware of then copper will no longer function for internet. If you have no internet capability then you will also not have a landline phone as it is all going to be changed to VOIP which requires broadband capabilities.

    Like I said I could be wrong but that is what the last open reach engineer I spoke to told me.

    I'm certainly not an expert either!

    AiUI the common VoIP protocols require either an 0.07 or 0.09 Mb/s internet capacity. We were previously on a 3-mile copper line which delivered around 1Mb/s, so fine for VoIP (but useless for anything else!).

    BT have a Universal Service Obligation to provide everyone at least 10MB/s, which they might do using 4G in rural areas, other 4G providers are cheaper. Fixed home installations with rooftop antennas can pick up a 4G signal even where smartphones can't find one. I suppose people could access their VOIP line that way, if the copper line is inadequate.

    We mostly have Apple phones (and tablets) and so do our families, so we use those to keep in touch via Facetime. The phones use our wi-fi signal so there's no cost and no need for any 'computers' to be on. The phones are on pay-to-go so we don't use them much outside the house. For friends with Android phones we use WhatsApp. We still have a landline which we use with a CSP. It's useful for family emergency calls because we turn the mobile phones off at night. (some relatives don't understand time differences!)

    Come 2025 I think our Dect handsets will work on VOIP as well, and our router also supports Dect phones over VOIP. I haven't checked all the details yet.

    PS Openreach were here a couple of weeks ago, asking how our phone cable entered the building and told me it would be replaced with a fibre using the same entrance (i.e. underground duct). Not quite sure when or if that will happen unless I ask for it.

    I am/was at the end of a 2mile copper line and was lucky to get 0.5MB/s. The problem is that when you were getting your 1MB that would have been copper line all the way. But as of 2025 the copper to the cabinet will be switched off and copper is only compatible with fibre over a much shorter distance compared to copper all the way. My understanding is 2 miles basically means no broadband and no VOIP capabilities.

    BT have a Universal Service Obligation but the Scottish Government has defined this as connection to cabinet so they could hit their own target (which they have missed the first part of). I am now on a wireless network which gives me a minimum of 60MB/s for under £35 per month with no contract. If I go away for 3 months I can stop the service and start it again when I get back. Wouldn't touch BT with a barge pole these days.

    The complexity of the answer is way beyond me.

    I don't mind having VOiP (if it works) but the various call packages are more expensive than I am currently paying. I have Anytime with John Lewis for around £6 per month and with that, can call oversea with 18866 and the month bill is around £3 per month.

    BT and Vodafone both offer VOiP but to get the JBL prices, will cost me around £13 with Vodafone. Why would I pay more?

    The 18866 web site says that BT block the carrier number but Vodafone told me that 18866 would work.

    Confused? You better believe it!

    "I am now on a wireless network which gives me a minimum of 60MB/s for under £35 per month with no contract. " Can you elucidate please?

    You think you're confused, so am I by what you've written :bigsmile:

    You can use 18866 with any phone provider as far as I know, so I don't know why you make a connection to JL? We use one of its sister products - 18185 - which seems to be slightly cheaper for us.

    The 18866 web site says that BT block the carrier number
    I believe that may be true although I have no direct experience. You can always use the freephone access number instead I think, though the tariff might be slightly different. (it seems strange that BT can block access to a competitor????)

    There's an article at https://uk.pcmag.com/internet-telephony-voip/132588/finally-ditch-that-landline-the-best-voip-home-phone-services?p=1 that lists some providers although there are others such as sipgate that have already been mentioned.

    We pay £14.60 /month for 4G internet and that includes unlimited calls, emails, web pages, iPlayer and all other kinds of internet traffic.

    Its amazing that these companies manage to make the market so non transparent and charge one customer twice as much as the next. Ripe for a shakeup.

    You may be right but as I understand it, one can only use the 18866 cheap rates from a registered phone. It makes sense because otherwise, who would 18866 invoice?

    I am paying more than that, but it is landline with John Lewis Broadband, who get it from Plusnet who are part of BT. What would I do to get 4g and from whom?

    I contacted 18866 with a technical request and this was their reply:

    "You would not need to use Carrier Preselection, nor would you need any VoIP service from your FTTP provider (unless you wished to) you would just require some VoIP device to connect to our service, you could then make all your National & International calls via ourselves. However I must point out that we do not support short code dialling, so no 101, 111 nor 999 service, however if you have a mobile these services are usually provided on their network."

    May be it is age related but I still don't understand. If I keep my copper land line but take FTTP for the internet, I know where I stand but will have to pay extra just to keep the landline.

    But if I accept FTTP with VoIP, still not sure about the cost of international phone calls via 18866 (if it is even possible?)
