Few years back, many people thought that advanced VoIP technology is going to be the “next big thing” in the telecom domain. Yes, now VoIP has a major impact on providers in the market which has turned out to be more of a commodity than a paradigm-changer. The main reason for the popularity of voice over IP solution is mobility, flexibility and scalability. The inherent benefits such as cost effectiveness and organisational productivity cannot be ignored. As a matter of fact, these factors have motivated businesses to manage their work with utmost efficiency. For making the various things possible, one solution is VoIP PBX.
The VoIP PBX system is a hallmark for businesses to inculcate double profits in quick time. This system permits the users to save substantial amount on long distance as well as international calls. Most importantly, business that manage calls over the IP PBX VoIP solution provide comfortable integration with existing PSTN telecommunication system.
An VoIP PBX system is a Internet protocol private branch exchange. This exchange is a business telephone system which is designed to deliver voice over a data network and is interoperable with the traditional Public Switched Telephone Network (PSTN). With low upgradation cost, almost every business users can make the changes as it is done through a specific software. As a matter of fact, the VoIP gateways can be combined with traditional PBX functionality which enables the businesses to use their managed intranet to reduce long distance expenses as well as enjoy the benefits of a single network for voice and data. The advanced CTI features of this IP system give greater cost savings, greater mobility and increased redundancy.
To be more specific, an IP-PBX exists as a hardware object or virtually, as a software system. This is because a major part of IPBX functionality is provided in software. The best part is that this system is relatively inexpensive in nature. One can easily add other functionalities such as conferencing, XML-RPC control of live calls, Interactive voice response (IVR)and TTS/ASR (text to speech/automatic speech recognition). Moreover, these advanced system supports public switched telephone network (PSTN) interconnection ability which supports both analogue and digital circuits, Voice over IP protocols including SIP, Inter-Asterisk eXchange, H.323, Jabber and GoogleTalk.
Therefore, it can be said that this high-end technology simplifies communication infrastructure at ease. The VoIP PBX system permits the users to co-ordinate with their multiple offices all around the globe with the support of an unified platform. Interestingly, the single IP PBX VoIP server has the potential to serve more than 1,500 users at the same time. As such, it seems to be an attractive option which can support business enterprise to gain more without any concern.
In comparison with a conventional PBX system, the users require separate networks for sending and receiving the voice and data communication but, VoIP PBX employs the converged data and voice communication over a single IP network. This increases the value of systems to a significant extent.
Moreover, the IP PBX VoIP also provides flexibility to the growing or new enterprises, as it can reduce the long-term investments and maintenance costs. The biggest factor that contributes to the adoption of anything new by the enterprises is cost involved in it. In the case of the VoIP PBX solutions, the costs are within limits of the enterprises. Nowadays, the business users do not have to spend more from their pockets for this system, as cost is coming down. The users must opt for the provider that offers bundled services and features. These advanced solutions enable the business users to make the most of services such as voice extensions or updation.
To conclude, the hybrid solutions offer greater scalability advantage when compared to the traditional PBX systems.

VoIP PBX – Next Big Thing to PBX System
February 9th, 2010VegaStream’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.

What Exactly is VoIP?
January 3rd, 2010
VoIP, acronym for Voice over Internet Protocol, is a common term used for a group of technologies involving transmission. This protocol is used to deliver voice communications across the internet protocol networks such as various packet switched networks like the internet.
VoIP is often referred to as Internet telephony, or IP telephony, and even voice over broadband. This protocol basically is a type of communication service that involves facsimile and voice messaging techniques and applications that are transmitted via the internet. These do not take help from the public switched telephone network (PSTN). The voice signal that is actually in analog form is first converted into a digital format and then the signal is translated into a format compatible with the internet protocol so that they can be successfully transmitted via the internet. This is the technique used at the transmitting end. At the receiver end these internet protocol packets that are received as digitized signals are converted back into analog form and sent to the receiver.
VoIP is a widely used technique of modern times. You can get connected to VoIP service providers by three primary ways: by an Analog Telephone Adapter, by using the Ethernet or Wi-Fi technique and by means of a softphone or a digital phone. VoIP has many advantages which have made it a successful service. It has high bandwidth efficiency and the cost of transmission is quite low. It also enables the performance of tasks and provides such services that are difficult to be implemented using PSTN making them highly flexible.
However VoIP is prone to internet attacks or what we commonly say that data can be hacked by experts and hence it is not a very secure technique. This problem has been taken into consideration and the government and certain military organizations are now using Voice over Secure IP (VoSIP) to protect data which is a modified version of VoIP
