Hybrid Fixed and Mobile Telephony 75

Iorek writes "Both Ericsson and BT have launched telephony products that erode the barriers between mobile phones and landlines. Ericsson's One Phone is a PBX system that can treat any mobile phone as an extension of the corporate phone network, while the BT Fusion handset behaves like a conventional fixed line cordless phone when it's near its base station (Bluetooth connection), and connects to the Vodafone network once it's out of range."

    So? Panasonic made phones like that as early as 1998.

        Well, I think the reason is because Cellular is a technology, not a brand name, and a lot of people don't understand that. The biggest advantage Cellular technology has is the ability to seamlessly route traffic between towers, so that if someone moves from Cell A to Cell B, that the users never notice.

        WiMax and other technologies don't dynamically route. So if you're downloading or calling someone, and you move out of WiMax area A, to WiMax area B, how do you disclose your new IP address to the caller? Ho

So if you're downloading or calling someone, and you move out of WiMax area A, to WiMax area B, how do you disclose your new IP address to the caller? How do you tell someone left the range of WiMax A? IP technology assumes a fixed IP address; VoIP rely on that fixed IP address to route the phonecalls to your Vonage or other phone.

      Bluetooth is more appropriate in many areas because bluetooth profiles are easier to support and implement than IP networking.

I could seriously use this at work, but, of course, they won't offer it to businesses since they think (perhaps rightfully so) that the business could get by with fewer lines. I think that these Ericsson and BT phones would be useful.

The only thing stopping this is the relative closedness of the Skype protocols. With a little effort and SIP knowledge you can already replicate most of this behavior. I'm sure Skype's next move will be a pay-for PBX of this sort. Meanwhile, let's get

      The digit '1' is not a toll indicator in the North American Numbering Plan. Its misinterpretation as a toll indicator is a historical artifact of the way that many telephone switching systems were setup in the relay era. When you dialed '1', your local step-by-step central office handed off the call to a toll switch, which could route and connect long distance calls. In the modern world, it tells the switch to expect another 10 digits. It does not indicate a toll call. A 11-digit number can be a local call and a 7-digit or 10-digit number can be a toll call. Programming all 11 digits into a dialer ensures that the call will be completed, whether it's local or long distance.
      • Perhaps not in the North America Numbering Plan, but it still is with many providers. With a land line from Bellsouth in my home town if I dial 1 + area code before I dial a local number I will be charged for a long distance call even if I am only calling next door. In fact this was the entire point of the parent post. Dialing a 1 might not mean long distance in the standard, but that isn't stopping providers from handling it in that way.
        • You need to complain to Bellsouth. There were similar problems here with Verizon when 10-digit dialing was introduced. These were quickly fixed. Bellsouth's billing software should be insensitive to whether the subscriber dialed 10 or 11 digits.
      • Here in Colorado, all switches expect ten digits and all calls are 10-digit calls. We have one of those abomniations called an "overlay"... the 303 and 720 area-codes are the same physical area. The whiney cell companies complained that Qwest wouldn't give them 303 numbers and that people wouldn't call new cell carrier's numbers if they had to dial what appeeared to the uneducated to be a long-distance call.

        I am always weirded out when I travel now that people can actually still make seven digit calls in
        • I also live in an overlay area. The first area code expansion was done with a split, subsequent expansions have been overlays. I think the overlay was less disruptive than the split.

          It used to be possible to dial local numbers in three different area codes (DC, MD. VA) with just seven digits. All of the exchanges in the metro DC area were unique. That was before cell phones and pagers exhausted the available phone numbers.

    BT has sunk millions of pounds into coming up with a solution which might have been really cool two years ago, but now looks dated.

    Quite apart from the Motorola V560 which is beginning to look like a bit of a relic, the system itself has lots of rough edges, is extremely restrictive and looks like a product in search of a market, not the other way around.

    Here's a different take on the BT Fusion / Motorola V560 / Bluephone [mobilegazette.com] thing. Not pretty.

    • "So.. if you like Motorolas, use BT Mobile or Vodafone and want BT Broadband AND you are close enough to an ADSL-capable exchange then you are in luck."

      That's more or less me. The mobile doesn't make me want to scream "Oh God YES I must have one", but also doesn't look too bad. I have a Vodafone phone, and have ADSL through my BT line. I'm not sure if the article actually means I'd need ADSL from BT Openworld, that might be a nuisance, but...

    Most cell phone companies have pretty good coverage. But, the #1 place I hear people complain about not having coverage is their home. Coverage is great on highways, in downtown areas, but once you enter a suburban residential area, coverage becomes questionable.
