A Cell Socket for Other Phones?

Posted by Cliff on from the interesting-twists-of-technology dept.

edstromp asks: "So I just heard about this neat device that lets you plug your cellphone into your home phone(s): CellSocket by Global Garden Group is one, but it only works on Nokia 5100's and 6100's. I am trying to convince my wife that we don't need a land line anymore (we both have cellphones), and I really think this would be the ticket. When you are home you can drop your cell into the cradle, and then all your home phone's will ring instead of your cell when someone calls your cell phone. Has anyone used one, and does anyone know if there are similar devices for other cellphones?"

  1. Why not just go the whole VoIP deal. by Neck_of_the_Woods · · Score: 5, Informative

    We are using VoIP service from Vonage. We don't have a land line at all anymore and can have a area code anywhere in the world if we want. Currently we have in New York and Florida so that we can get local calls from all of our family, and all our toll calls are local as well. IE we pay 40 bucks in the north east and get unlimited toll and long distance with our family having just local calls to us. They send e-mail for your voice messages, and are I hear about to compress your voicemails into mp3 for email. You get to see all you incoming and outgoing call on the web. Everyting was just what we where looking for. Christ I sound like a commercial...

    We are planning on going to Cali or Col. for a contract job and just need to pack up our Cisco adapter and plug it in there. It does not care what network your on as long as it gets a dhcp address from somewhere.

    Only words of caution that I have is that is done not work well behind a software router. Any of the cheap hardware routers for broadband work fine so far. Hell I have even taken the thing down to florida and used it on a dialup network so I could make free calls for 2 weeks while I was down there.

    Anyway, not to sound like a comercial but it is a very cool way to save some money on your phone bill.

      Sounds kinda neat. It's not for me because I use DSL, so I have to have local telephone service anyway, but it's an interesting idea. How's the quality? Is there a noticeable echo or lag? Does it sound like a regular land line or more like a digital cell phone call? Have you ever had any problems with calls dropping or failing to go through?

      Thanks for any elaboration you can provide.

      Quality to land lines is the same, no one I call can tell the difference.

      I had a lot of droped calls at first going though a software proxy(ISA). Once I striped it out of the picture everything worked great. I have used it though a linksys, dlink, cisco, and one other little no name brand dsl router I can't remember at a friends house.

      We love it, although the only drawback is if your broadband goes down so does your phone. Alas that has not happend in over 8 months of use.

      Just to catch a couple of other questions I see coming. It has about a 33k stream from what I can tell and does not mess with anything else on your network. I could tell you the ports but that would just take the fun out of it. You can use a poor man's router set up if you like.

      What else...you really can't tell any differnce in this and a land line. Dial tone, call waiting, call blocking, called id...we use it with our normal phone. Any phone that plugs into a wall will work with it. I can't think of anyting else, if you have a question about it post it here I will try to answer it to the best of my knowledge from using the service.

      Unfortunatly they do not cover the areacodes I am in (Aparently only two citys in Ohio, nether of which are mine)

      I emailed to ask if they had plans to support my areacode soon or not, so hopefully Ill get a good reply from that soon.

      Do you know of any other companys that provide this same service?
      I would love to use something like this to replace my landline, but needs to have POPs in atleast my areacode heh others for family and friends are just a perk.

      This would have more to do with the way your company network is set up. This is one of those questions that you would find in a certification book with the answer "This questions and answer session does not cover the scoop required to answer this question".

      Short answer is if it was my network, no because it would end up being blocked...and you would end up going out a proxy..which would hose it up most of the time.

      Just set the thing to forward to your phone at your desk.

      I had this for about 2 months. It worked well initially, but ATT Broadband decided that they would block all SIP (5060/udp) traffic to Vonage.com's network. I was able to get SIP traffic through to other places on the net, but not to Vonage. I verified this with a sniffer outside of my firewall to make sure the packets were going out, and then a Vonage tech verified he wasn't receiving them on his side.

      For awhile ATT was NAT'ing the traffic, but *only* the SIP traffic. Regular tcp connections and traffic on other UDP ports were not NAT'd. But eventually, they blocked it completely. I called them and finally got someone to fix it, but two weeks later, it stopped working again and I cancelled the phone service because I didn't want to spend 3 hours on the phone with ATT every 2 weeks.

      I would assume they blocked it because of their own competing service. Vonage does have customers using ATTBI, so it does work for some people. But if you're in Minneapolis, chances are you may have some problems.

      It's not for me because I use DSL, so I have to have local telephone service anyway...

      When my DSL was set up I had that as a question, and the ISP said that they specifically set up my service so that would be a non-issue. While I must have wires to the CLEC, I don't have to have any phone service at all. They said that they rig it that way now because they had expected problems where people would kill (or lose) phone service, but blame the ISP for lost connectivity. Since the ISP/CLEC relationship is sometimes shaky at best, they said it saves lots of phone calls. They've had a fair number of customers go all-cellular, or switch local carriers and worry about lost DSL in the interim.

      If your DSL company doesn't do it and you're willing to hop, shop around for someone who's willing to do it.

      My ISP (Soltec) is a little more expensive than others, but the service is incredible; they're willing to remotely administer my Speedstream (5861) router*, but also willing to let me take over if I want. The tech who helped set me up is a former student of mine when I taught high-school, so there was no jerking around.

      * a cool piece of equipment if ever there was one!

      Same here, this is why my cell phone has been my only phone for the past 4 years. I've had two telemarketers call, both from companies I have services from (Credit card and TV service). Before they even got far into the call, I interrupted them with "Do you know this is a cell phone?" Their response was to apologize and promptly hang up. Telemarketing to cell phones is against the law in the US.

      To answer the question of the poster, Vox.Link was another product that worked with the same Nokia phones, plus some Motorola and Ericsson phones. Their website is www.vox2.com, though right now I can't resolve the IP.

    Just for your information -- unless you can lock the phone into analog operation, don't even try hooking a modem to this thing. I wouldn't even recommend using a fax on it. The audio compression used in digital cellular and PCS will ruin your throughput.

    1. Re:FYI - don't do net by TheSHAD0W · · Score: 2

      Digital cellular and PCS use a voice-grade compression, which squeezes your conversation down to about 4kbps, in each direction. Your 14.4kbps, 9.6kbps or even 4.8kbps fax connection will not handle the compression at all well, and in the case of data transmission, even at 2400bps or less you're going to see data corruption.

      With analog cellular, on the other hand, you've got two actual analog radio channels dedicated to the conversation, and while noise would be a concern, a modem signal with error correction can squeeze through it.

      Yes, fax devices and modems must be linked directly to the digital feed. Without a modem, PCS can got at 9.6 or more without problems. In such a case a computer deals with the phone as if it was a fake modem and the phone recodes the info as frames to go over the net which get converted back to analog at the provider's end.

      Useless with this thing because the digital connection can only be made through the base of the unit (where this unit connects).

  6. Hey, I worked on one of these! by Matt_Bennett · · Score: 2

    I worked on one of these- when I worked for Andrew corporation, I did some hardware and coding for the Extensis (mentioned below). Trying to get it to act like a landline was pretty tough- there is no really set way to determine when the call should actually go through- I ended up with a complex state machine based on a bunch of inputs, like how many numbers dialed, pause between the digits, and what number was dialed. (911 gets you right through, for example) The biggest downside I see is that 911 doesn't give the operator your address instantly in case of an emergency (yet, at least). Also, you're going to be pretty limited in the number of telephones that the device can power- You're probably not going to get one of these cradles that will drive the normal phone company max load of 5B (about 5 normal old telephones with mechanical ringers)

    You can't use a digital phone for any sort of modem, but otherwise, it should work great. The first generation I worked on was for a motorola Star-Tac type phone. These are pretty complex little devices.

    Motorola actually had this back in the early 90's. Basically, they just built in the internals of a cordless phone into a standard cell phone. The prototypes I saw looked exactly like the original "flip phone", except the case was black instead of grey.

    You'd set up a base station at home that looks and functions exactly like any portable wireless phone base, and when you are at home, your "cell phone" would just be another extension of your home phone line.

    The same Motorola facility also had a way-cool "microcell" attached to the local office PBX, so your cell phone would work just like your desk phone when on the local Motorola campus.
