Unlike any other Bluetooth headsets, the Plantronics Voyager 510 USB Bluetooth headset is the first to simultaneously support both VoIP softphones on your PC and your Bluetooth mobile phone simultaneously -- negating the need to deregister/re-register your Bluetooth connection with the other device. Plantronics is able to do this using their exclusive Multipoint Technology. Measuring 4.0 x 2.5 x 0.8 inches and weighing 5.6 ounces, the Plantronic Voyager 510 headset is pretty lightweight - after awhile you don't even notice it is there. It is slightly heavier and bulkier than the Click for Amazon price:

Many PCs or even laptops don't have built-in Bluetooth, but fortunately, the Voyager 510 USB includes a plug and play Bluetooth USB adapter that works without the need for any software drivers. This enables mobile professionals to engage in one-step hands-free VoIP calling. If you want the ability to perform remote-end answer/hang-up integration with softphones you'll need to install the PerSonoCall application. The system integrates with enterprise softphone software from leading companies — including Avaya, Cisco, Nortel, Skype, and others — to offer call notification and remote call answering through the headset. It also is compatible with most popular consumer VoIP services, like AOL, MSN, and Yahoo! although it doesn't feature remote call answer with these yet. I tested the ability to remotely answer incoming Skype calls from the 510-USB and it worked without a hitch. On an incoming Skype call from Greg Galitzine I simply pressed the call control button on the 510-USB and the Skype call was accepted. Beauty, eh? Profile of the Plantronics Voyager 510 USB Bluetooth Headset The headset's "smart" technology knows which Bluetooth device you are using and allows you to take calls from any device simply by hitting the button. With the optional Plantronics Bluetooth Deskphone Adapter you can even switch between your office phone and your Bluetooth mobile phone. Thus, you won't need to use a dedicated "landline" phone headset. The 510 headset features a noise-canceling microphone for clearer conversations and the mic boom swivels to position on either ear. The 510 supports adaptive frequency hopping (AFH) which helps avoid interference from WiFi networks. It supports a hefty 6 hours talk time using the built-in Lithium polymer rechargeable battery and up to 100 hours of standby time. Front View of the Voyager 510 USB Bluetooth Headset When you place the headset on the charging base, it automatically turns off the headset and charges it. Fortunately, when you remove the Voyager 510 from the charging base it remembers to turn it back on. Similarly, if you manually shut off the headset (depress power switch for 3s) and then place it on the charger, if you remove the headset from the base, the headset stays off. I wonder if the headset isn't truly "off" when you place the Voyager headset onto the charging base while it is still on? It's probably in a pseudo-sleep mode, but not totally powered off. The difference in charging the battery is probably negligible, so most users will probably keep the headset always turned on even when charging. Plantronics USB 510 charging base connected to 1 USB port. Bluetooth dongle connected to PC's 2nd USB port Button functionality & testing I had some minor difficulties with the power on/off switch which is very small and located just in front of the volume buttons, and it requires a very hard press. When the headset is on your ear, making a hard button press took a little getting used to. In any case, there are basically three buttons on the headset. The first button is simply a +/- volume button, which happens to be the largest of the three making it easy to adjust the volume. The 2nd button on the 510 is the small black button I mentioned which toggles the power button (and mute with a quick depress). The power button requires you hold the button for 3s to toggle the power. Well, they advertise in the manual that it's 3 seconds, but I tested it and it's actually 3s to turn on and just 2-2.5s to turn off. The 3s is a tad long to turn on, but useful I suppose to prevent accidentally turning on or off the headset. Of course, like I said, you have to press the power button pretty hard, so I doubt it would be pressed by accident. It probably has more to do with the time it takes to negotiate a connection with the other Bluetooth devices. The 3rd button on the Voyager is placed where the boom mic meats the ear piece and it is used to call answer or end the call, as well as toggle between your PC Bluetooth connection and your Bluetooth mobile phone. It is also used to activate voice dialing, redial, and other functions. To activate last number redial you simply double click the call control button. You will hear a high tone for each key press. When you hear a further tone, the last number has been redialed. In addition, when receiving an incoming call you can press and hold the call control button to reject a call. You will hear a tone. When you hear a second tone, the call has been rejected and you can release the button. Voice Dialing & Call Transfer to other BT device You can easily perform voice dialing supported by your mobile phone by pressing and holding the call control button for 2 seconds until you hear a second tone. Then you can speak the name of the person you wish to reach. Switching a call from your mobile phone to the headset is pretty straightforward. You simply briefly press the call control button. Switching a call from the headset back to the phone requires a slighly longer button press until you hear a tone indicating the transfer has been complete. I was able to listen to streaming music on the 510-USB, hear beeps in the headset that an incoming call was coming in, and then press the call control to answer the call. Features

• Multipoint Technology allows you to seamlessly switch between two Bluetooth devices
• Noise-canceling microphone for superior sound quality
• Up to 6 hours talk time and up to 100 hours standby time
• One-touch call answer/end, last number redial and voice activated dialing
• Compatible with Bluetooth devices supporting the headset or hands-free profile
• Noise-canceling microphone and wind-reduction technology for brilliant sound both indoors and out;
• Lightweight, foldable design for all-day comfort and easy storage;
• Boom swivels for use on either ear;
• 33-foot roaming distance. feet away from voice-enabled Bluetooth devices

Pros - Lightweight - Flexible and foldable to stow in pocket - Cool charging base - Excellent Sound Quality - Comes with 3 different sized ear pieces for the best fit - Includes a small portable USB Bluetooth "dongle" to Bluetooth-enable any PC/laptop - Range performance was good - better than other BT headsets I have tested Cons - Too dependent on the time a button is depressed for some functionality - another button to take the load of one of the features might be good - Power switch is small and hard to depress - USB Bluetooth dongle doesn't have a key ring to put in on your keychain - Can switch from listening to PC audio (music or Skype call) to an incoming mobile phone call, however if you switch from the mobile phone to your PC (music or Skype call), it ends the mobile phone call. I wish there was a way to switch to the PC (put caller on hold) without disconnecting the mobile phone call. Conclusion The Plantronics Voyager 510 USB is one of the best if not the best Bluetooth headset you can buy, period. Its ability to register with both your PC's audio software applications (including VoIP) and your Bluetooth-enabled phone is a key differentiating factor. The audio quality was very good and the headset itself is very flexible making it very comfortable to wear. I didn't have any issues with the headset losing the Bluetooth connection (cutting out) at all and the range is very good. I highly recommend the Voyager 510 USB. The Click for Amazon price:

WiMAX-enabled VoIP phone showcased at Mobile World Congress

www.youthsprouts.blogspot.com Ridiculous quantities of 3G handsets weren't the only things showed off at this year's Mobile World Congress -- oh no, NetIndex, Kaga Electronics and Runcom shook up the norm a bit with their WiMAX-enabled portable VoIP phone. Reportedly, the trio joined forces to develop a VoIP handset that utilized a 802.16e module, and aside from "realizing all-IP voice communication," it also sports a web browser and integrated WiFi for times when a plain ole hotspot will do. Sadly, we've no idea where this thing will go after it leaves Barcelona (nor what it looks like), but here's to hoping it makes a commercial debut -- and can decide on a single logo -- in the not-too-distant future. __

HOW VOIP WORKS? AN EASY WAY

www.youthsprouts.blogspot.com

1.) Get a good, fast and reliable Internet connection To use VoIP, you need at least broadband Internet connection, sad to say that dial-up will just frustrate you. There are lots of Internet Service Providers (ISP) today who offer high speed Internet connection via broadband (DSL) or dedicated Internet (ISDN) connection.

2.) Make VoIP calls The next step is to decide what type of VoIP calls you would like to use, there are couple of scenarios about this below:

a.) Computer to Computer VoIP call

This is the “basic VoIP connection”, the caller and the called party’s computers must be online, must have headsets attached to the computers’ sound cards. The computers must be connected to the Internet and must be running VoIP software. Most VoIP softwares available today are free and allow you to connect to any computer running the same software. Skype is the best example of this free software. There is no charge for this type of call and calls can be made to anywhere in the world if you are aware of the IP address (other VoIP softwares use phone number) of the computer you would like to call.

b.) Computer to Phone VoIP call

For this type of VoIP connection to work, one party must be online, running VoIP software and has subscribed to a VoIP provider who offers PC to Phone VoIP calls and vice versa while the other party is using a phone that is not connected to the Internet (regular or mobile phone). Let say for example the caller is the one on the computer with VoIP software and the called party is the one who has a traditional phone. The caller dials the number from the VoIP software running in the computer. The call is then routed through the Internet and was received by the VoIP provider, the VoIP provider with an interconnection to Public Switched Telephone Network (PSTN) then routes the VoIP call to the called party’s regular or mobile phone.

c.) Phone to Phone VoIP call

You can make/receive VoIP calls using an ordinary telephone or an IP Phone. If you would like to use an analog phone, you must have an Analog Terminal Adapter (ATA). ATA is a device that allows you to use a regular phone unit to make VoIP calls. An ATA must have a valid IP address and must be connected to the Internet. If you would like to use an IP Phone (sometimes called SIP Phone or VoIP Phone), you don’t need an ATA at all, the IP Phone is connected directly to your Ethernet Hub which is connected to your ISP’s baseband or DSL modem.

d.) Analog or mobile phone to another analog or mobile phone VoIP call

“YES, there is such a VoIP call folks”, you won’t notice it but majority of the telephone companies today are starting to migrate their interconnection to other carriers to VoIP. This is pretty simple, you use your regular analog line to call another analog line, your telephone provider then routes the call over a VoIP interconnection to the destination telephone provider (assuming they have VoIP interconnection) using a special commercial-type VoIP equipment (e.g. Quintum or Cisco). You are actually connected to the called party but you are unaware that the conversation is passing through VoIP channels.

NOTE: This type of VoIP call is for telephone companies only, an SMB with a remote office can also use this to dial a number from the remote corporate PBX using their local corporate PBX to save money from long distance calls.

Free voip software. talk voip free

www.youthsprouts.blogspot.com Skype is a proprietary peer-to-peer internet telephony (VoIP) network, founded by Niklas Zennström and Janus Friis, the creators of KaZaA. The Skype Group is headquartered in Luxembourg with offices also in London and Tallinn. The system has a generally favorable reputation for working across different types of network connections (including firewalls and NAT) because voice packets are routed by the combined users of the free desktop software application. The basic computer-to-computer service allows users to speak, to send instant messages or to send files to one another from their computers via the Internet at no cost. Conferences of up to five users are supported. SkypeOut is a paid feature of the Skype internet telephony service, which allows Skype users to call virtually any non-computer-based landline or mobile telephone in the world. SkypeIn allows Skype users to receive calls on their computers dialed by regular phone subscribers to regular phone numbers. Beta released on March 10, 2005, SkypeIn permits users to subscribe to numbers in UK, USA, France, Hong Kong, Denmark, Finland, Norway, Sweden, Estonia and Poland. Cost is €30 for a 12-month subscription, or €10 for a three-month subscription. Users can have multiple SkypeIn phone numbers bound to the same account (a separate subscription is required for each). For example, someone who does business in both San Francisco and Helsinki could create a local telephone number in each city, and callers from those locations would pay cheap or free local rates. On September 12, 2005 eBay announced its plan to acquire the company for $US 2.6 billion, plus an additional 1.5 billion in rewards if goals are met by 2008. eBay will pay half in cash and half in stock options. Google Talk is a service developed by Google for instant messaging (IM) that also allows for PC to PC audio conversations. Google Talk beta was released on August 24, 2005 and consists of both a service and a client used to connect to the service. Unlike some other instant messaging services, Google Talk uses an open protocol (Jabber) for the IM part and it encourages the use of clients other than their own in connecting to the Google Talk service. As of the launch date, the Google Talk client is available only for Windows (2000, XP, Server 2003); users of other operating systems are provided with instructions for various popular Jabber clients, such as Psi or Miranda IM for Microsoft Windows and below, iChat or Adium for Mac OS X and Gaim for Linux. However, any program capable of using the Jabber protocol is sufficient, although the voice over IP service only works with the Google client. Google claims they will release a specification for the voice extension in the near future. GnomeMeeting is an open source VoIP and video conferencing application for GNOME. It is based on the OpenH323 library and primarily uses the H.323 protocol, although support for SIP is in development. It supports many audio and video codecs, and is interoperable with Microsoft NetMeeting. GnomeMeeting was written by Damien Sandras in order to graduate from the Université catholique de Louvain. ineen is a VoIP network that allows free IP Telephony calls. ineen has a laundry list of features which include voice, video, conferencing, distributed conferencing, speakerphone, call transfer, and instant messaging. Unlike other software, ineen took the approach of an interface that models a normal phone. The software is available for Windows, Mac OS X, and Pocket PC. Jajah Jajah is a proprietary peer-to-peer internet telephony (VoIP) softphone. With Jajah you can speak to other Jajah-, SIP-, IAX- or Skype-users for free. Jajah offers free VoIP-communication, including internet calls, video calls, live chat, text messages, call forwarding and telephone conferences. To call a landline or mobile phone worldwide you'll have to top up your credit at their website. Receiving calls from traditional phones is not yet possible but planned. __

Microsoft-response-point-sp1

www.youthsprouts.blogspot.com Today, Microsoft released announced Microsoft Response Point Service Pack 1 (SP1), which adds SIP trunking support. Response Point Service Pack 1 (SP1), not to be confused with the recent release of Vista SP1, will be released this summer, available free via a simple download. I spoke with Microsoft last week and they said they are partnering with several SIP-based ITSPs, which will enable Response Point administrators (or VARs) to easily add SIP trunks and move away from analog trunks. You simply use a VoIP account setup wizard in the Response Point Administrator, to connect with Internet telephony service providers (ITSPs) and add new VoIP phone numbers. The other benefit is the ability to add local phone numbers. Microsoft espoused the need for many small businesses to maintain a local presence. By leveraging VoIP providers businesses can select a local phone number for use in remote locations. Additionally, SP1 adds direct-inward-dial (DID) to directly reach a particular user's extension or pool of extensions. I asked Microsoft's thoughts on T1 trunks vs. SIP trunks and if they felt the need for T1 support was still there for the SMB, but they wouldn't comment. However, the impression I got was that they might add T1 support in the future. Personally, I think SIP trunking makes more sense for the SMB and it has proven itself cost-effective and reliable. But don't be surprised to see T1 support in the future in RP. Response Point hardware vendors Aastra Technologies Ltd., D-Link Corp. and Quanta Computer Inc. will ship end-to-end Response Point phone systems, pre-loaded with SP1, this summer. The SP1 release will coincide with Aastra's Response Point phone system debut, which is interesting when you consider Aastra got into the IP-PBX game with a Microsoft IP-PBX competitor last week - the AastraLink Pro 160 appliance, an Asterisk IP-PBX derivative. Here's a screenshot of the Response Point admin from my review back in November. No doubt the Phone Service portion will have SIP trunks listed when you add them in. Lastly, check out my Microsoft Response Point review if you haven't read it already to get a feel for this product... It's most note-worthy feature is the speech-recognition capabilities. __

GOOGEL ON FOR THE WHITE BAND FOR WiFi AND BACKS IT BUT WHY ?

www.youthsprouts.blogspot.com Photo City-wide wi-fi networks are beginning to be rolled out across the United States. One of the most high-profile is a network operated by search giant Google.

While poring over hidden charges on your cell phone bill, or writing hefty cheques to your internet service provider, it's hard not to think there should be a better way.

Anything but high prices and no choices. Well, I'm starting to think there is, and I caught a glimpse of it in the city of Mountain View, California.

In the first week in August I drove down to Mountain View on a sweltering afternoon looking to test out the promise of free or cheap phone calls and ubiquitous internet access over a city-wide wi-fi network.

Thanks to Google, the city has been blanketed by wi-fi, which will soon allow its residents to connect to the wireless internet all over the city for free.

Using a technology called mesh, Google has placed hundreds of wi-fi nodes on lamp posts around the city that can connect your laptop or handheld device to the internet. For a town that gets the service, it's like living in a giant wi-fi hotspot.

WiFi Q&A EXPLAINED BY BBC WORLD

www.youthsprouts.blogspot.com Wireless hotspots are spreading across the world's cities, with blanket wi-fi zones now being rolled out in many city centres. Operators are promising wireless surfing at the touch of a button from the park, the bus or the street corner. So what does the wireless future have to offer and will it live up to the hype?

What is wi-fi?

Wi-fi is the acronym for Wireless Fidelity, essentially a set of standards for transmitting data over a wireless network.

Wi-fi allows you to connect to the net at broadband speeds without cables, as long as you have the right equipment and, in most cases, a regular internet service provider and a wi-fi account.

To understand the technology behind wi-fi, imagine using a walkie-talkie. Your voice is picked up by a microphone, encoded onto a radio frequency and transmitted with the antenna to another walkie-talkie, which decodes your voice.

Wi-fi works in broadly in the same way, but using a better radio that is capable of handling a lot more data per second.

HOW DOES WI-FI WORK? 1: Wi-fi uses antennas around which wi-fi "hotspots" are created. The hotspots are outlets equipped to receive the radiowaves that power wireless networking. Until recently, wi-fi has been confined to more than 10,000 hot-spots in cafes, bars and airport lounges. But various projects are under way to set up city-wide zones, where a series of antennas are installed in the streets, on lampposts or street signs. The hotspots around them together create a much wider area of coverage. Norwich has a mesh network which links each lamppost antenna to the next creating a seamless wi-fi hotspot around the centre of the city. 2: The source internet connection is provided by a PC or server to which the antennas are connected either wirelessly or via a cable. 3: Some mobile phones and personal digital assistants (PDA) now have wi-fi chips installed. With mobile phones, this means conventional networks can be bypassed and inexpensive long-distance calls made over the web (using Voice over Internet Protocol, VoIP). 4: Many laptops and handheld computers now come with built-in wi-fi connectivity; it is also possible to add wi-fi to your computer with a special card that plugs into a port on your laptop.

How do I use a giant wi-fi zone?

In the UK, there are already more than 10,000 wi-fi hotspots in public places such as restaurants, hotels, cafes, libraries and airports.

Wi-fi-enabled laptops and phones can be set up to connect to these hotspots automatically; usage is generally paid through a credit card at a login page on a web browser. Frequent users may even have accounts with service providers such as T-Mobile, BT Openzone, O2, SkypeZones and Nintendo wi-fi.

Will it catch on?

So far, wi-fi has been a service that is most useful for business people who need to work on the move; but operators want to make it available to all.

However, some analysts warn that wi-fi could be the "next dotcom crash", mainly because of patchy hotspot coverage, lack of enabled hardware and uncertainty over how to make money.

There are still a few big challenges ahead for wi-fi. Finalising interoperability and standards is one, and the concern over security is another.

Just because there are more than 10,000 wi-fi hotspots in the UK does not mean that a pass to use one means you can use all of them. Currently wi-fi hotspots are divided by who controls them.

In Norwich the local authority and regional development agency are pioneering a free wi-fi service. This model could catch on, if successful. More than 3,000 connections are being made to the city's wi-fi network each week

Logging on to the internet via wi-fi in different locations brings the risk (just as it does at home or in the office) of your computer being infected by computer viruses and worms. Experts advise you to install security software and update it regularly.

Who stands to profit?

Some critics argue that wireless hotspots can be a rip-off - the price of installing a wireless router in, say, a coffee shop, involves a one-off cost of a few hundred pounds but customers may be charged upwards of £5 an hour.

Users of the new city-wide wi-fi networks will be required to pay access charges to an account provider, such as BT Openzone or T-Mobile.

The revenues will be shared between the owners of the street furniture on which the equipment is installed (usually local councils), wi-fi hotspot suppliers and the internet service providers.

Google believes the spectrum could create a wi-fi dividend

www.youthsprouts.blogspot.com

Google's home is in Mountain View, California

Google is pressing the US government to allow the unlicensed frequencies of TV "white space" to be used for wi-fi.

The firm has written an open letter to regulators saying the US spectrum was a "once in a lifetime opportunity".

White space is unused blocks of frequencies in-between channels broadcast on analogue airwaves.

"The vast majority of viable spectrum in this country simply goes unused, or else is grossly underutilised," wrote Google's Richard Whitt in the letter.

"Unlike other natural resources, there is no benefit to allowing this spectrum to lie fallow," he added.

Google has said the white space could be used to bring "ubiquitous wireless broadband access to all Americans".

In the past TV broadcasters have opposed the use of white space, fearing it would cause interference with television programming.

Google believes the spectrum could create a wi-fi dividend

But in its letter, Google urged the FCC to adopt a series of overlapping technologies, including "spectrum sensing," designed to prevent signals from interfering with each other.

Mr Whitt said there was enough unused spectrum for businesses to create a wide range of options, such as building small peer-to-peer networks or even establishing an alternative national wireless network.

Google has said that devices designed to take advantage of the white space spectrum could be on the market by the end of 2009.

Other countries are also looking at using white space spectrum.

In the UK much of this space is being dedicated for use by services like wireless microphones for broadcast use, and for cognitive radio, a smart wireless technology that allows for the use of wi-fi.

What is voip?

www.youthsprouts.blogspot.com

VoIP stands for Voice over Internet Protocol but what does that really mean?

Basically… You must already have a home phone and an Internet connection so why not combine both and save yourself some money? Using your existing internet connection you can transfer over your home phone number to a VoIP service provider.

Many people have the misconception about VoIP that you have to sit at your computer and use a headset to make calls. This is no longer true because now you can even use your cordless phone and no one will know the difference. Depending on your location, you can find VoIP service providers almost anywhere.

The bigger company does not necessarily mean better service, so do your homework before getting VoIP service. Here is a link for a website that I came across which does an excellent job of comparing VoIP providers from around the world.

WIFI A GREATE RANGE FROM NOW. FOOD FOR RURAL INTERNET.

www.youthsprouts.blogspot.com

Message received: This Wi-Fi router from Intel uses specialized software to send data to a receiving radio more than 60 miles away. The goal is to connect sparsely populated rural areas with urban cores. Credit: Intel

Intel has announced plans to sell a specialized Wi-Fi platform later this year that can send data from a city to outlying rural areas tens of miles away, connecting sparsely populated villages to the Internet. The wireless technology, called the rural connectivity platform (RCP), will be helpful to computer-equipped students in poor countries, says Jeff Galinovsky, a senior platform manager at Intel. And the data rates are high enough--up to about 6.5 megabits per second--that the connection could be used for video conferencing and telemedicine, he says.

The RCP, which essentially consists of a processor, radios, specialized software, and an antenna, is an appealing way to connect remote areas that otherwise would go without the Internet, says Galinovsky. Wireless satellite connections are expensive, he points out. And it's impractical to wire up some villages in Asian and African countries. "You can't lay cable," he says. "It's difficult, expensive, and someone is going to pull it up out of the ground to sell it."

GTalk2VoIP AND Talkonaut

www.youthsprouts.blogspot.com We are at GTalk2VoIP Team continously working on making our voice services more robust and easy to use. Though all our services can be used from your existsing beloved instant messenger without any additional downloads, we developed some software products for you, to expend capabilities of our gateway. These products are:

• Talkonaut - A Google Talk like application for mobile phones (Java capable). Allows you to chat, to make voice calls to IM clients, SIP phones and PSTN.

google talk to GVOIP. AGAIN GREAT THING FROM GOOGLE

www.youthsprouts.blogspot.com

An Internet user should have an email account and uses Instant Messenger (IM) of any kind; it could be Yahoo! Messenger, MSN, Jabber, Google Talk, Skype , Gizmo, etc… It has been obvious that the primary use of Internet, aside from information retrieval, is communication. Instant Messenger is always there for a real-time chat and talk. And we can still make use of these IMs to work with the VoIP infrastructure. GTalk2VoIP provide this service, bridging the gap of IM compatibility. GTalk2VoIP provides both premium/paid and free services. GTalk2VoIP free services includes free incoming calls from PSTN, free outgoing calls to SIP phones, free incoming calls from SIP network, free internet radio broadcasting, voice mail service, voice conferencing service, free off-line messaging, free Instant Messaging interoperability, call from the Web service, and GTalk2VoIP for Your Domain service. Paid service includes all free services mentioned about and on top of that, subscribers can do outgoing calls to mobile and landline phones (PSTN), callback initiated by IM message, and SMS service. For more details of these services, click here. Rates may vary from country to country and the service provider. GTalk2VoIP infrastructure uses the VoIP technology which can be depicted in two parts: VoIP Gatewaying core and Finite State Machine. The GTalk2VoIP gateway can be logically devided into two separate and/or independent parts: 1) VoIP gatewaying core and 2) Finite State Machine. What are they and how do they interact to each other to accomplish required effect we will try to briefly describe here. The figure below is also provided to ease the explaination.

1. VoIP Gatewaying core.

The Core in essence is our own implementation of a VoIP soft-switch. It consists of a number of VoIP signal processing stacks, like: H.323, SIP (including Yahoo's and Microsoft's perverted "dialects") and Jingle Audio of course. It also includes media codecs, transcoders and conferencing rooms (the last are just a subtype of transcoders).

Signalling stacks can initiate and receive VoIP connetions from a TCP/IP network (which Internet is) and produce a number of operational events to upper level - to Finite State Machine. Signalling stacks can be connected to each others using conference rooms or transcoders, so media streams from one type of stack can go through another, thus implementing a VoIP gatewaying between different type of VoIP networks. Control over signalling stacks interconnections is driven by operational commands which are generated by FSM. Transcoders also do conversions of voice compression algorithms (media codecs) used in voip networks.

For example, when GTalk user is talking to SIP user, media data from GTalk are usually encoded by iLBC codecs. These data are getting decoded by transceder into linear PCM16 format then encoded back into G.726 or GSM format (codec).

2. Finite State Machine.

Finite State Machine (also can be refered as Sinite Automatoc) is a very important part of any PBX or a soft-switch. FMS is a logical machine, the commonly used technology, aimed to handle a large number of events and to control states of some operational objects. FSMs usually can be configured by a set of rules and procedures (predicative logic).

In terms of GTalk2VoIP gateway, the FSM is used to handle a numerous calls states and to control call processing objects (H.323 and SIP stacks) by generating control commands. When a call from GTalk arrives, a Jingle Audio stack emmits an INCOMING_CALL event to FSM. The Machine, according to configuration rules loaded into it, then generates ACCEPT command to Jingle Audio stack, and CALL commant to SIP stack (or H.323 stack, depending on how call must be treated). When CALL command initiated, another event comes to FSM, this time it indicates call progress state. The process continues till the call ends.

Finite State Machine also handles incoming messages from GTalk users and threat them like commands to execute. When you type CALL message, the Machine initiates a call to your GTalk using Jingle Audio and do the rest stuff.
