Wifi Voip Phone

The call control protocol of the WF01 is based on SIP V2 (Session Initiation Protocol version 2, RFC 3261) open standard, which is interoperable with major SIP-based call servers, IP-PBXs, and other standard SIP-based client devices. The WF01_V2 is compliant with the IEEE 802.11b standard and interoperates with any existing 802.11b or 802.11g wireless AP and gateway. It may be used as a cordless handset for residential users or for business users in an office environment. The small form factor of the handset is easy to transport and allows users to place VoIP phone calls in public 802.11-based environment.

Modem with one ethernet port, have two units to plug in?

I have a Motorola SURFboard SB5101U cable modem. It has one Ethernet port and one USB ("square" type) port. I have an Apple Airport Express wireless plugged into the Ethernet port.  Here's the problem.  I want to use "MagicJack Plus" (VoiP) without plugging it into the computer (THE difference from the "regular" MagicJack, that it (the Plus) can be plugged directly into the modem, bypassing the computer, so the computer doesn't have to be left on 24/7 for your phone service).  My question is, can a simple Ethernet (pigtail) splitter be used to plug both the MagicJack Plus and the Apple Airport Express wireless into the modem?  I know this can be "Physically" but is the "signal" degraded in any way to the two units?

Is it possible to add voice effects to outgoing VOIP calls?

The subject line pretty much says it all... I'm intrigued by the idea of prank calling my friends by processing my voice through audio effects (i.e. - using VST/AU plugins). I'm not even sure if this is possible, but it seems like there must be a way. I think illformed's Glitch plugin ( http://illformed.org/plugins/glitch/ ) would be perfect for something like this. Any tips on how to hook this up? FYI: I normally make VOIP calls via my MacBook Pro, and I have Audio Hijack and a plethora of software effects installed already. However, I'm open to any and all suggestions - even if they can't be done with my existing setup. Thanks!

Audio over rj11

I was wondering if I can have a audio input on a rj11 so I can run audio off my house's phone lines. We have VOIP now and don't use the phone lines, so can I still do that?

How does one hack the school firewall to access UDP ports for a VOIP telephone?

I bought a magicJack for internet telephone service. It works great at home and since the device is small and portable, I thought I could bring it to school and have a telephone in my room while there, too. However, the device cannot access magicJack's servers so it doesn't work. MagicJack says it uses a given range of UDP ports. Apparently the district computer Nazis have blocked access and they aren't going to open them for me. Can I open them myself?

Resources: Add Value.

I like to learn stuff from someone who can do what I want to do and will answer my questions. I don't like extraneous material cluttering the path to my goal. The greatest achievements are made through cooperation. We all stand on the shoulders of those who cooperated to achieve the point where we should start. And the greatest achiever will lift us there, so we can lift the next achiever. We disserve ourselves, our ancestors, and our progeny when we hoard our results and pretend to be smarter than the next achiever, when rather than showing where we left off and where he should start, we instead slow our collective progress by placing the next achiever at our feet, and requiring that he review the mistakes we have already made and learned from. Time is too short. In a cooperative efficient society, no one reinvents the wheel.

How do I get my Google Voice number to make free calls w/out a VoIP or a SIP?

As I just found out, not all of my calls incoming or outgoing are always free with Google Voice as I was led to believe. I read somewhere by simply adding my GV to my friends & family on my calling plan, my incoming calls will all be free. In order for my outgoing calls to be free, I need to somehow get my carrier to "recognize" my GV number as being the number that is dialing out as opposed to the masked numbers it uses when dialing. How do I accomplish this?

Phone Headset

I would swear I saw an Instructable on this somewhere, but now I can't find it. I have an old corded telephone that I want to rewire. I just want to take the actual handheld part and attach it to a standard 2.5mm stereo output, such that I could either plug it into a cell phone and have a giant cool headset, or use it with my speaker/mic splitter to do VoIP-type work on the computer. Do phone cords have standard colored wires? Am I just going to have to figure it out myself? The headset has a standard 4-contact CAT-1 phone jack, and I want to take one end off a phone cord and replace it with a 2.5mm plug.

How can I get Linux on a T-Mobile phone?

     I have an old T-Mobile Dash cell phone.  I want to run some form of Linux (or another open-source OS) rather than Windows Mobile.  I want to be able to do open-source voIP, text, etc.  I also want to be able to use T-Mobile's supposedly excellent international coverage (I'm going to England).  The phone can connect to a computer and has a microSD slot.  Any recommendations are welcome.  Thanks! P.S.  I heard that I could partition off part of the microSD to use as extra RAM.  How do I do this? I'm also thinking of toughening it up to survive drops, falls, water, etc.  Any recommendations as to what to do for that are appreciated.

Network connected telephone answering machine

I was hoping that SOMEONE made a telephone answering machine with a network connection so that it would do its thing like any other digital answering machine but the messages could be managed over my network. So I did a google search and it seems others have also been interested in such a thing - albeit the most recent queries being at least a year old. The answers were - "I already have that on Vonage" - sorry - don't want voip!! And various programs that would let your computer, with voice modem, do that including linux programs. Well - I don't have a full blown computer on all the time and am not likely to. And so I thought - how about a small computer - but don't have one - couldn't think of one ... And then I thought ..... Raspberry PI!!?? So small and low power that it could even be put in an old answering machine case and low power draw. Does anyone think its enough computer to do this?  Anyone up to inventing one?

Government Trojans !!!

What do you all think of this practice ? Coming soon to a pc near you....government trojans.A government Trojan is spyware installed on a computer or network by a law enforcement agency for the purpose of capturing information relevant to a criminal investigation. Depending on the program, government Trojan horses may intercept email or VoIP traffic, scan hard drives for relevant digital media or even record conversations and videoconferences. As this type of software captures data and then sends it back to a central server for processing and analysis without a user's knowledge, it is generally classified as a back door Trojan horse virus. Governments have approached implementing Trojan horses in different ways. Swiss government agencies have been reported to be working with Internet service providers (ISPs) to record speech on an infected PC's microphone, as opposed to of intercepting encrypted voice packets. German agencies have sought authority to plant Trojan horses on the hard drives of suspected criminals using email that would install keyloggers, record webcams and microphones and scan infected hard drives for for documents, diagrams and photography. These email messages would be tailored to each unique target, similar to the method used in spear phishing attacks.More about Government Trojans.

Brainstorming - Teamspeak PTT Bluetooth Device

Gurus of the Tech World, First off, I'm browsed through a lot of great idea and I've got to say, you all are geniuses.  Hopefully, someone can help steer me in the right direction.  I have made a few Windows Phone apps, made a few HTML websites and some networking fundamentals, but I've never really made a device... much less soldered a board. With that said, I want my first project to be a Bluetooth Push-to-Talk (PTT) button for Teamspeak.  I have a Bluetooth headset with a microphone for Teamspeak (VOIP PC Application) so I can hear people speaking while being away from the computer but I do not have a way to communicate back using the Push-to-Talk method. So, what I want to do is make a small Bluetooth device, maybe powered by a 9V, with a single PTT button, and maybe an ON/OFF switch to save power.  My thought is to program it so that it send a keystroke to my computer for the duration that the PTT button is pressed (CTRL would be ideal).  This is something that I want to make, using as much of my brain as possible and the least amount of prefabricated merchandise ("omg, just buy a bluetooth dongle and plug it into a button. ta-da"). I'm sure that this is something you guru's can do blindfolded, but, please, point me in the right direction... and use baby words. Thanks! Stryker2k2 (@stryker2k2)

Using a Rhino FXS Analog Chanel bank to actuate a relay

Ok so i've got a VOIP system that's connected to a Rhino FXS Chanel bank  that's used to control our overhead paging system. From the Rhino we go to a Volcom analog adapter to a Volcom Stacker unit (echo cancelation). Every once in a while this system will "lock up" and just throw static over the paging system (and even more rarely someone will put the overhead paging system on hold which pumps our hold music over the intercom system)...to combat this i've got the Rhino, the adapter, and the stacker pluged into a surge protector so that when the "abnormal condition occurs" we just flip the switch on the surge protector and it drops the whole system. then we turn it back on and all is well.This works great but the system is in a remote location in the facility so it takes a bit of walking to get to it. What i'd like to do is try to hook up a NC relay between the surge protector and the wall and have an open channel on the Rhino actuate the relay to basically turn the power off to the system any time you dial a specific extension.According to the datasheet the Rhino itself has a line current limit from 18ma to 45ma and it emits standard telephone line voltage....i can also configure the ring cadence...so i can probably set the ring duration long enough to actuate the relay before it cuts the system off (which would then return the relay back to closed)i'm having trouble finding out what the actual output voltage on the analog line and a general lack of schematics to try to make this workso...if anyone wants to have a little fun attempting to design a relay that can be actuated by a telephone...please reply

Long Range Off the Grid WiFi Repeater

Hello Everyone,  I've got quite the project that I am undertaking and I am looking for a bit of advice. This will be my very 1st forray into long-distance wifi, as well as off-grid power resources, so Im biting off quite a bit at once! I have a friend who has been helping me with the research who has a much firmer understanding of both electricity and hardware, but he will be out of town for the next week and I would like to get a bit of progress on this while he is gone. SO, I shall consult the hive mind known as the internet. Alright, this project consists of creating an uplink between a remote shed, and a home in a nearby city, with a broadband connection. The rub, there is 10,000 ft mountain range in between the two. We have a site were we can put a repeater node at approx. 10,000 ft elevation, that has wonderful line-of-sight to both locations. However, this site is very remote, and will have to run off the grid obviously. The distances are as follows: Home to repeater: 3.96 miles (thats with Google Earth following the contours of the          mountain/valley, not sure how to make it just do a straight angled shot, so thats a rough estimate) Repeater to Remote shed: 2.68 miles (same issue) Background environment info: shed has generator + 60w solar array with 3-4 deep discharge lead RV batteries at 7400 feet. Has spring fed running water, which could be utilized for power as well, as obviously its always running. Repeater location is at 10k, as stated. Moderate to high winds very likely (data from peaks of similar altitude in the general area show gusts ranging from 40-60 mp/h, temperature ranges of  averaging 7 to 90+ for a the later part of July and August (F). Obviously, its very possible to get soemething below this, though the lowest Ive ever seen at the shed has been -15 (f), I would say most winters we could get a few nights that see temps below 0, but not often. Equipment Ideas: So to pull this off, we have come up with two ideas for the network equipment, which I shall discuss 1st, then I will show you what we have come up with for power.  - Network    - Repeater Node: rb433 wireless access point ($99.00) http://www.routerboard.com/pricelist.php?showProduct=43         with 2 r52h mini PCI wifi chips ($59.00 x2) http://www.routerboard.com/pricelist.php?showProduct=69         2 8-18 inch satelite dishs converted for long-range WIFI use (20.00 x2) http://www.engadget.com/2005/11/15/how-to-build-a-wifi-biquad-dish-antenna/ OR instead of a rb433, we could use 2 WRT54G Linksys routers like this. (I also have 2 BEF 801.11b routers that are legacy to the WRT54G. I would like to use this if possible! http://hackaday.com/2005/08/23/how-to-greyhat-wifi-repeater/ Now, I know that this later choice would increase power use by about double. From what I have been able to find, the WRT's would at anywhere from 4.2w to 8w of power. Anyways, I like this later choice because it would be significantly cheaper for the equipment, but do you have any other ideas? I know that the RB433 would work great, but its rather expensive all said and done after I throw up the power as well. Plus, if it takes a lighting strike, its out of commission, and 2 cheap linksys routers are much cheaper to replace! Anyways any input here would be great! - Power  so power to the repeater node is the real challenge. We crunched the numbers and came up with something almost exactly the same as below: From the datasheets, a routerboard will draw between 6-10W. So design for 10W. Over 24 hours you will need 10Wx24h = 240 Watt.Hours of power. For 7 days, you need 7x240Wh = 1680 Watt.Hours. A single, large deep cycle 110Ah 12V battery gives you about 1320 Watt.Hours of power, almost meeting the requirement. Now, to look at the solar panels: A good rule of thumb is to install 6 times the wattage that is drawn by the device. This is because only about 8 hours a day in sunny weather gives you maximum power output from a solar panel. So the other 16 hours you need to draw from the battery. (So already you need 3 times the wattage drawn by the device to break even each day) To generate 1 full day of extra battery power per sunny day, you need another 3 times the wattage. This is how we arrive at 6 times. 6 x 10W = 60W. So at a minimum I would recommend 60W of solar panels. That qoute comes from http://diywifilink.wordpress.com/ and http://mybroadband.co.za/vb/showthread.php?179547-Advice-needed-Setting-up-wifi-repeater-11km which is a project from a guy in South Africa almost exactly the same as the one that we are working on. The numbers came out to be about the same (Though they were a bit different when we calculated for the WRT54G option.) so, 60w of power generation to keep a decent charge on a battery. Now, we have a 60w panel at the shed, which is rather large to take up to 10,000 ft and place on the side of a mountain, and given the consistent wind element up there, we are hoping to do a hybrid system of both solar and wind. This is where things get tricky. A perfect balance, or even a more wind heavy balance would be great, such as 30-40w wind 20-30w solar. That keeps the panel size down, and uses a power source that runs 24/7. A Faroun Savonius wind turbine seems like the best system, but the controller to prevent overcharging etc is where I get nice and lost, having breached into very unknown territory. https://www.instructables.com/id/Faroun-Savonius-Wind-Turbine/ http://www.fieldlines.com/board/index.php/topic,129060.html This looked at 1st like a good, cheap system to use a controller board for the wind, but my question is would the controller board that comes with these solar panels (see below) work for both. That below is the setup that we use more or less at the shed, with some mods, such as a better alternator. http://www.costco.com/Browse/Product.aspx?Prodid=11298029&search;=solar&Mo;=5&cm;_re=1_en-_-Top_Left_Nav-_-Top_search⟨=en-US&Nr;=P_CatalogName:BC&Sp;=S&N;=4001192&whse;=BC&Dx;=mode+matchallpartial&Ntk;=Text_Search&Dr;=P_CatalogName:BC&Ne;=4000000&D;=solar&Ntt;=solar&No;=3&Ntx;=mode+matchallpartial&s;=1&topnav;=&Nty;=1&s;=1 So, can a small, 30-50w wind turbine and generator be built, with a small solar array to power this thing? I dont care if we have some down time, this is primarily going to be used as a system to get a weather station with web cam to send in hourly photos during the peak hours. I can have the system at the shed shutdown automatically  using some cron jobs in linux during the evening to conserve power. When there are people at the shed, we would like to be able to get a good enough wifi connection to use a wifi device (such as an android phone or ipod) to use as a voip phone in essential communication. The teenagers aren't going to be chatting with their friends for hours, but we would like to be able to put a short call through in case something goes wrong, or we just need to get ahold of someone at the shed or in the city. Next the equipment at the shed should be comparable to the repeater node,  sans 1 antenna and just some low power embedded system. We would like to get a webcam and weather station hooked up on this end, but that can wait for upgrades later if needed, if power doesnt allow it. like I said, a simple water turbine could be used (something similar to the wind turbine perhaps?) and even another wind turbine could be built to add extra power dedicated to running any system at the shed, though I dont think the wind is quite regular enough to be viable here, but if its cheap, we could throw it on anyways. equipment at the home in the city is simple, just use an extra laptop or desktop we have laying around to be server/router, hook up antenna to this, broadcast connection, run the weatherstation/webcam web server off of this. So, thats the plan, but load of input is needed to try to come up with this. We hope to try to keep this sub $1000.00, but the budget could go higher. This is DIY at its finest! Thanks in advance for you help!
