Analog Telephone Adapter

Analog Telephone Adapter

An Analog Telephone Adapter (ATA), also known as the Analog Telephony Adapter, is an electronic device used to enable one or more analog telephones or facsimile machines for Voice over Internet Protocol (VoIP) calls and faxes. An Analog Telephone Adapter basically creates a physical connection by use of telephone and internet cables between a conventional phone or fax and a computer or an Ethernet gateway. The ATA usually comes with a digital phone and internet plan provider but it can also be bought independently. The Analog Telephone Adapter makes voice calls and faxing over the internet possible without the user needing to upgrade existing

VoIP Gateway

VoIP Gateway

A VoIP Gateway, or Voice over IP Gateway, is a network device which helps to convert voice and fax calls, in real time, between an IP network and Public Switched Telephone Network (PSTN). It is a high performance gateway designed for Voice over IP applications. Typically, a VoIP gateway comes with the ability to support at least two T1/E1 digital channels. Most VoIP gateways feature at least one Ethernet and telephone port. Controlling a gateway can be done with the help of the various protocols like MGCP, SIP or LTP.





The main advantage of VoIP gateway is that it can provide connection with your existing telephone and fax machines through the traditional telephone networks, PBXs, and key systems. This makes the process of making calls over the IP network familiar to VoIP customers.
VoIP gateways can end a call from the telephone and can provide user admission control using IVR (Interactive Voice Response) system and provide accounting records for the call. Gateways also help direct outbound calls to a specific destination, or can end the call from another gateway and send the call to the PSTN.
VoIP gateways plays a major role in enhancing carrier services and also supports the simplicity of the telephone calls for less cost and easy access. Flexible call integration has been developed at less cost which enables programmable call progress tones and distinctive ring tones.





Functions of VoIP Gateways
The main functions of VoIP gateways include voice and fax compression or decompression, control signaling, call routing, and packetization. VoIP gateways are also power packed with additional features such as interfaces to external controllers like Gatekeepers or Softswitches, network management systems, and billing systems





Future of VoIP Gateway Technology
Over the years, VoIP gateway has become an efficient and flexible solution and is used for office data and voice connectivity. Besides the connectivity performance, VoIP also offers better reliability under a variety of circumstances.
The future of VoIP gateway is very clear and precise; high-density, scaleable, open platforms need to be designed and implemented to allow the millions of installed telephones and fast-growing number of H.323 computer clients (such as Netscape's Communicator and Microsoft's NetMeeting) to communicate over IP. Many vendors are in the process of designing interoperable VoIP gateways according to the latest architectures to meet the changing demands of service providers, corporate network clients, and individual carriers

VoIP phones with Wi-Fi / 802.11

VoIP phones with Wi-Fi / 802.11

Wi-Fi (802.11) VoIP phones provide the same service as Ethernet VoIP phones, but they do it wirelessly.
A Wi-Fi enabled VoIP phone connects to a VoIP server or VoIP gateway through your existing Wi-Fi network.
VoIP phones with dialup modem connections
VoIP phones with dialup modem connections are very similar to VoIP phones with Ethernet connections.
Instead of connecting to an Ethernet network, these VoIP phones dialup over the PSTN to VoIP service providers.
Using a VoIP phone with a dialup modem connection requires a regular analog POTS telephone line, but enables long-distance and international calls to be made over VoIP networks, usually at a significant savings.
Software VoIP phones
Software VoIP phones turn your PC into a VoIP telephone.
Software VoIP telephones are less expensive than the choices listed above, if you already own a personal computer.
Hardware for Software VoIP phones
Software VoIP phones use the PC's sound card, speakers or earphones, and microphone. This hardware works to emulate a telephone, even though this is not what the PC was designed for.
For better ease-of-use, many companies manufacture USB VoIP phones. These devices give your PC a normal-looking telephone handset or headset.

Get free VoIP

Get free VoIP

The first thing to know about free VoIP calls is that none of them are actually completely free. Even in the best hypothetical case in which the VoIP provider doesn't charge you at all, remember that you still have to pay for your broadband Internet connection. You must understand that the goal is not to achieve completely free calls to all destinations, but to use the VoIP operator that suits your needs best. Keeping that in mind, you will learn that most VoIP companies will let you talk for free in their own network but also they will charge you for making calls outside their proprietary network.
The main way for free VoIP calls companies is to offer free calls inside their own network and also towards other specially selected destinations. Using this tactic users are drawn to make calls to free destinations and afterwards purchase credits to make calls towards paid destinations.
There are several ways used by VoIP companies to lure customers and make a profit in the same time. The great thing about VoIP calls is that they're very cheap, but not completely free, here are some systems used today in the VoIP calls market:

If you take Skype for example, one of the most popular VoIP services on the market, you will see that you can initiate conversations with other PC users of Skype free of charge. Of course, this is an advantage for long distance calls, as there is no fee for calls inside the Skype network. But if you want to make calls to regular landlines, you'll have to pay. The subscription fee for calls in North America is $30 per year. It's not a great deal of money but it still isn't free. You can make free phone calls on a PC to PC basis using the Skype software, and the number of users on the Skype network is continuously growing. On the other hand if you want to reach someone that doesn't have a PC or an Internet connection, you'll have to pay the required fees.
Another approach to this, could be the way Raketu is seeing things. Raketu is offering free phone calls to landlines in 42 countries and besides that, it also offers live video television. The downside to Raketu's service is that they ask you to pay $9.95 up front in order to use their free services. They say it's used as credit if you happen to call destinations that are not on the free call list, but either way you look at it; it's money that you have to pay to use the

VoIP Features

The biggest advantage of VoIP is that the customers can make calls from anywhere in the world where a broadband internet connection is available. The customers can take their IP phones or ATA's with them on national and international trips and still can manage to access what is essentially an individual's domestic phone line.
Then there are the softphones, which a software application that loads the VoIP services onto the desktop or laptop. Some even simulate an interface that looks like a telephone, with which you can place VoIP calls to anybody around the world, through a standard broadband connection.
Most VoIP services come with the caller id, call waiting, call transfer, repeat dialing and three-way dialing features. For additional features such as call filtering, forwarding a call, or sending calls directly to the voice mail, the service provider may assess an additional fee. Most VoIP services also allow the user to check his/her voicemail over the web or attach messages to an e-mail that is sent to his/her PDA or PC.
Generally, the facilities and components provided by VOIP phone system suppliers and service operators may vary in significant ways. It is advisable to check the pros and cons before subscribing. Make sure that you have available technical support for the possible compatibility issues that could arise between the existing and new hardware components

How Voip Work

How Voip Work

The most common way VoIP works is that the end user establishes a hi speed broadband connection, a router and a VoIP gateway. Instead of a standard telephone line, the router sends the telephone calls over an internet connection. The VoIP gateway, placed somewhere in direct proximity of the connected Internet converts the analog signals into digital format, which are further broken down into smaller chunks called 'packets', before sending it over the internet, much like the way data is transmitted to and from the computer. These packets are sent to their final destination and instructions for bringing back into an understandable form are embedded in them. It then goes through a VoIP gateway where the packets are reconverted into the original analog format utilizing a PSTN (Public Telephone Switch Network), thereby routing the call to the number the caller has dialed blending old school technology and hi tech delivery in a seamless and instantaneous way.
