VoIP Guide- Some Guidelines for VoIP

January 16th, 2010



VoIP refers to voice over Internet Protocol. This latest technology provides voice conversations over Internet or via IP-based network. In VoIP technology, protocols are used to carry voice signals over Internet Protocol network. VoIP is also known as IP Telephony, Internet telephony and Digital Phone.

Nowadays VoIP technology is very popular. People generally like to use this technology because its costs are less than traditional phone. Several large corporations use this IP technology to increase their working area. Everyone is currently familiar with voice chat software. Internet protocol telephony has some additional advantages over traditional phone lines.

VoIP technology enables you talk to several people simultaneously. You can also send some other types of data like files, with the help of VoIP. It offers different services with developing technologies. VoIP enables you to send any type of data at higher speeds of Internet.

Several devices can easily receive IP calls. It doesn’t require hardware but some software programs like Skype are required to install on your computer. Some national companies such as Verizon and AT&T also offers VoIP services. Vonage was the very first company that offered voice over Internet protocol services at reasonable rates.

Due to developing technologies, it is said that VoIP has a great future. It has gained a large number of clients in a short period. Its installation procedure is very simple and anyone can easily handle it with a little knowledge.

VegaStream’s Introduction to VoIP

January 13th, 2010



Internet Telephony is used to describe a service that enables people connected to the public Internet with a suitably equipped PC to have voice conversation; examples of Internet Telephony providers include Skype. VoIP is the generic term for the technology that enables phone calls to be made over networks running the Internet Protocol, be that the public Internet or private IP networks. It is also the term that is used to describe the technology in a business to business context. One could say that the consumer will use Internet Telephony while businesses use VoIP.

Voice over IP (VoIP) converts the analog signals of sound when using a telephone to a digital format for transmission across a data network and then back into analog when it reaches the receiver. In a VoIP network, digitized voice data is highly compressed and carried in packets over an IP network. The phones can be purpose-built devices for the IP network (e.g. SIP phones) or standard everyday analog telephones. VegaStream core product range allows users of existing phones to take advantage of VoIP networks.

What’s all the hype about?

The reason for VoIP’s popularity is a simple matter of physics. You can put more traffic over the same physical network using IP than you can with traditional telephone technology, Time Division Multiplexing (TDM) as used by the public switched telephone network (PSTN). This simple law is driving many PSTN network providers to migrate their existing TDM networks; that have served them well since the invention of the telephone, to the new IP technology. BTs 21st Century Network is a classic example of this migration.

With VoIP, IP allows us to use a single high-speed Internet connection for all voice, video, and data communications. This is known as convergence and is one of the primary drivers for corporate interest in the technology. The benefits of convergence are obvious. By using a single data network for all communications, it is possible to reduce overall costs.
Furthermore, the business model for data networks, including the Internet allows the customer to remain permanently connected at a fixed price. Meanwhile, when using traditional PSTN, the meter starts running every time you pick up the phone.
The idea of VoIP communication dates back over 20 years however, a greater interest in the applications of VoIP emerged in the 1990’s, with the growth of the Internet. The Internet made it possible to interconnect every home and every business with a packet-switched data network, this saw a rapid growth in VoIP technology. Today, with broadband connectivity the norm not just in business but also at home and even over the mobile, the platform is set for an explosive growth in VoIP.

VoIP Changing the Way We Communicate

VoIP offers a great deal more than cost savings in telephone calls. VoIP technology allows devices to recognize and communicate with each other as if they were connected over a dedicated wire (like the TDM model). It therefore enables video, instant messaging and data conferencing as well as voice. Furthermore all these communications techniques can be used simultaneously allowing people to share images and information as well as hear each other speak – all on the same call.

VoIP communication therefore allows us to actually change the way we communicate with each other. Communicating over the phone with VoIP will be more immediate, collaborative, visual and cost lest. No wonder the market for VoIP equipment and services is the fastest growing sector in the IT industry.

VOIP

January 6th, 2010



This article contains the excellent information about the Voice Over IP Protocol.

Voice over Internet Protocol (VoIP) technology is the wave of the future in terms of telephone communication via the Internet. VoIP has several advantages over circuit-switched technology used by local phone companies. Circuit-switched technology uses a ‘permanent’ connection between the caller and callee, which requires a huge amount of bandwidth for each call.

This type of technology can only carry certain types of calls, such as telephone to telephone. Also, the hardware circuit-switched networks need to run effectively are extremely expensive, mostly because voice and data services must be supported on different wires. Therefore, each service needs separate hardware to accommodate the voice and data types of traffic. Needless to say, your local phone company then passes the costs of building and maintaining a circuit-switched network to the you, the consumer. Unforturnately, this equals higher rates for your telephone services.

VoIP – How Does it Work?

VoIP technology is when phone calls travel networks using Internet Protocol (IP). What this means is that the calls are passed through the Internet or privately managed data networks that are using IP to send the calls from one location to the other. So whether the call is passed through the Internet or data networks, the voice stream is broken down into packets, compressed, and sent toward their final destination by several different routes.

This is where circuit-switch technology and IP technology differ, in that circuit-switched technology uses a ‘permanent’ connection for the entire phone call. Once the call reaches the callee, the voice stream packets are reassembled, decompressed, and switched back into a voice stream by several hardware and software elements, depending on the call’s final destination. The type of software and hardware needed to start and end a phone call is determined by where the call originated, such as a PC, phone, or an Integrated Access Device (IAD) and whether the call is going to be completed on a PC, telephone, or IAD.

ADVANTAGES OF VoIP

The following is a list of the numerous advantages for using VoIP:

· Voice and data can be sent over the same lines.

· 8 time the number of phone calls can be placed on those lines than in the circuit-switched environment.

· Quality of sound is excellent.

· Lower operating costs due to reduced hardware requirements and a more efficient network infrastructure.

· Lower cost structures enable lower rates than the traditional telephone companies.

· Use of different devices to talk to one another.
