BT Plans Move To IP Telephony, Starting Next Year 228

Posted by timothy from the kin-y'-hyeah-me-now dept.
pure_equanimity writes "The BBC have published an article saying that BT are planning to migrate from a PSTN to an IP network, a move to cost 3bn. They say that broadband will become ubiquitous, with customers having the ability to plug any device in to get access. They also say that current cheap broadband products will more than likely not be viable in five years time. They plan to start rolling out in 2006, and cover the vast majority of customers by 2009."

          25/mth is quite good in the UK actually, but 25 pounds = 45 USD. You could probably get 1.5mbs with a good provider in the US for $35, and in Canada for less than $25 ($20 USD). In Japan and HK, you get 10+mbs for around $20 USD.

          Telewest has just increase it's bandwidth by 50% though (no change in the plan price though). 512->768k, 1.0->1.5m etc. It's great and probably a good deal if you want 1mbs and don't have bulldog in your area.

        Indeed, that's what they say. However, as ip telephony can be expected to use a miniscule fraction of the bandwidth on a broadband connection, and IP telephony service isnt that expensive to set up, they'd have to figure out a way to lock you in, easiest by controlling and raising the price on your broadband as it would be much harder to control and overcharge for IP telephony service.

        Actually, PSTN does stand for Public Switched Telephone Network - the public bit meaning not private (as in PABX - Private Automatic Branch eXchange).

        Packet switching on telephone networks is a relatively new thing (compared to the history of automatic telephone switching). Until 20 years ago, most telephone switching was still done by electromechanical machines (google for Strowger Telephone Exchange) - huge rooms full of physical switches (uniselectors, bidirectional selectors) and relays which moved and clattered as subscribers dialed telephone numbers; the tones (such as ringing, number unobtainable, engaged etc) generated by a motor-driven machine. If you go to the London Science Museum, they have part of one of these exchanges you can play with.
        Trunk calls were routed using analogue frequency division multiplexing rather than packet switching. Signalling between mechanical telephone exchanges was done at voice frequencies (for example, the famous 2600Hz tone - in Britain, the frequency was different and it was known as 2VF - if you listen to some Radio 4 radio plays you'll find the sound engineers still like inserting the 'pip' sound when someone answers a call which you heard when the 2VF signalling wasn't quite fully supressed from reaching the subscriber's phone. These 'pip' sounds probably disappeared from the public network 20 years ago but the sound engys at the BBC seem to like them).

      Did you comprehend the article? This is more about their internal network, rather than the customer equipment.

      They will convert their entire internal network into VOIP, so even if you have an old analog POTS line, your calls will be VOIP'd between exchanges.

      Naturally, once they have a native internal VOIP network, then they're in a better position to offer interesting VOIP services directly to the customer. But a vast majority of customers will still be using analog POTS.

      It's hardly surprising: if they don't do this then they will fall behind in offering the kinds of innovative services that upstart VOIP vendors can offer. It also makes for better service integration and interoperation with future 4G technologies, etc.

    It's worth pointing out that this may not be a done deal.

    In the UK the telecoms industry has until recently been regulated by an organisation called Oftel. They have recently been replaced by a much broader regulator called Ofcom (http://www.ofcom.org.uk/).

    Their job is to try and ensure that the communications industry as a whole remains competitive. Which generally involves keeping BT on a short leash.

    This is the first major announcement from BT since Ofcom came into existence, so they may want attemp

    One of these would be extremely good for the UK and very forward thinking, the other would be investing money in a technology already straining to bursting point...

    And on another note, how cool will it be to have links like <a href="phonecall:phone.mydomain.com">Phone Me!</a> on websites - how long until we have that I wonder?

    I work for BT and have known about this for a few weeks now, seems like a move in the right direction

    Now they just have to start offering good internet and phone products to win customers back ;)

    BT (British Telecom) used to be a public subsiduary of the British post office (I believe). However, despite the fact it is its own company, it is *heavily* regulated by Ofcom, the telecom regulator. Basicly, about 90% of UK broadband providers provide ADSL (Asymectrical DSL - meaning faster Dl that Ul) from BTs network. This wasn't the case but Ofcom forced BT to allow other networks to run on the network at low cost, and also forced BT to allow very cheap rates for commercial isps to offer unlimited 56

    Asterisk [asterisk.org] is a complete PBX in software. It runs on Linux and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in three protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware.

    Asterisk provides Voicemail services with Directory, Call Conferencing, Interactive Voice Response, Call Queuing. It has support for three-way calling, caller ID services, ADSI, SIP and H.

    I think a lot of people including the press are missing the point here. The main thing here is not VoIP or fibre it is that BT are going to be migrating all of their services onto ONE IP network off of there existing PSTN, ATM and IP networks.

    Obviously while this will eventually have implications for end users (BT are talking of a broadband dialtone) the main benefits will be a big cost saving for BT and the ability to quickly deploy new services onto the network.

    This means:
    "Mr Beal hinted, however, that the cheap broadband telephony deals available at the moment may not continue." (from bbc article).
    NOT that broadband itself is going to get more expensive...

    You can simulate a VoIP call and get the MOS voice quality score. So if you want to see how your Wireless setup fares, visit testyourvoip.com [testyourvoip.com].

    Even if you don't care about VoIP, it is a useful test of the latency and bandwidth of your connection. VoIP is pretty sensitive to late packets so this tool highlights connectivity problems.

  • Italy already carries 80% of phone calls as data (Score:4, Informative)

    Telecom Italia already carries 80% of its national backbone telephone calls on an IP based network infrastructure, and something like 40% of their international calls.

    This is the back-end of the service, multiplexing together thousands of calls over high speed (2.5 and 10Gb/second) network links. The network also uses class of service and many other configuration setups to ensure a consistent quality of service for the traffic flow. You can be sure everything will be massively resilient. In addition this traffic won't traverse the public Internet at all, but will be on a private network (though gatewayed to the Internet for connectivity to other services). This will allow BT to guarantee they wont be hit by Internet related issues like congestion, black-hole routing and so on. Dont compare this service to public Internet VoIP, its NOTHING like it.

    Personally I think this is a fantastic move, and will really help the UK take advantage of up and coming technologies over the next decade.

    PS there is already an Internet standard to map IP addresses to public phone numbers, and there is also work on integrating VoIP into the DNS infrastructure!
