Voip technology pdf


















This book will provide a lot of useful information about current VoIP technology research aimed at practitioners and researchers as well as advanced graduate students. This book offers a comprehensive overview of the issues to solve in order to deploy global revenue-generating effective "multimedia" services.

This thesis documents an investigation into the technology of Voice over Internet Protocol VoIP VoIP promises to be a widely accepted technology in the future, The issues of efficient use of bandwidth over network choke points, cost Telephony over the Internet In recent years there was a huge growth of interest in protocols for voice transmission over the network.

In addition to IP phones, you can also access VoIP phone systems using your own mobile device, computer, and other network-ready devices with VoIP apps or softphone application installed. Today you can make and receive business phone calls anytime, anywhere using your own Internet-connected devices, without worrying about losing VoIP call quality.

Employees are no longer tied to a desk phone and may use any device of their choice. A VoIP gateway is a hardware device that converts traditional telephony traffic analog or digital into packets of data, allowing connections between legacy telephony infrastructure and IP-based communications, acting as a bridge between an IP network, the PSTN Public Switched Telephone Network , and the cellular network.

Modern businesses enjoy using VoIP phone service over traditional telephone lines because they can get a lot more value than just improving corporate communications.

Below are a few of the many ways VoIP benefits businesses. VoIP is a budget-friendly way to set up a business communications system. VoIP services could be based on a direct IP connection to your phone service provider, simply on your existing internet connection, or a combination of both. Therefore, it cuts down the cost of internal calls in your organization to virtually none, greatly reduces the expenses of external and international business calls, saving a significant amount of investments on purchasing traditional phone lines, installation, and ongoing maintenance.

On-premises and cloud-based VoIP systems are both cost-effective but do have some differences in terms of the cost. Though you need to pay fully upfront for an op-premises system, it protects you from the risk of fee increases and means lower monthly cost after expenses are covered. As for the cloud-based hosted VoIP services , you usually go with an OpEx model with more affordable monthly or annual fees and low initial equipment cost.

If your voice and data solutions are currently separate, you can save money by combining the two under one provider. Comparing to traditional phone systems, the installation and configuration of VoIP systems could be super easy. Traditionally, with a landline system, office phones require physical lines to receive phone service. VoIP phone systems eliminate the need to install any physical phone lines.

All you need to do is to connect IP phones to the corporate network via Ethernet lines. Better yet, if you need your IT staff to prioritize more important and revenue-generating projects instead of managing the phone system, hosted phone services leave the work to the service provider and there is no need to worry about any network issues.

It would be beneficial for small businesses and start-ups lacking in technical expertise or resources, too. When Voice over IP was first introduced, its call quality was indeed unsatisfactory.

Long gone are those days thanks to the advancement of broadband and Voice over Internet Protocol technology itself. Rest assured as long as you have a fast and stable Internet connection.

Most VoIP providers offer a vast number of different protocols and codecs to ensure HD sound quality. With a robust solution and proper implementation, the voice quality of VoIP can be as good or even better than the landline-based calls.

VoIP enables businesses to extend their communications system to remote offices and on-the-go workers over SIP-enabled devices. For remote workers, the office is wherever they make it as long as the Internet connection is available.

The deployment of a multi-site VoIP system can not only keep all dispersed branches connected seamlessly but also reduces the spiraling inter-office call costs. Softphones enable employees to make their office extensions mobile with a wide range of call handling features at hand.

Additionally, cloud phone systems make it easy to connect geographically dispersed offices under one phone system and the IT admin can easily manage it from any location.

Scalability, as one of the most valuable characteristics for businesses, refers to the ability of a system to handle a growing amount of workload, normally by adding resources to the system, without affecting its overall performance or efficiency.

VoIP is a scalable solution that can grow with your business, especially the cloud-based VoIP service, which offers greater flexibility for businesses with staff growth or reduction. The increase and decrease of phone extensions can be made immediately and businesses only pay for what they need, without purchasing additional hardware equipment or new dedicated lines.

It can all be done, practically in real-time. If you are a seasonal business with fluctuating communications needs or experiencing rapid growth, a hosted model can be a perfect fit for you. VoIP services deliver a number of features that are either not supported by traditional telephone systems or only available for an additional fee. Many businesses have found it easy to use VoIP and became more competitive with the full suite of built-in features.

If you have a special VoIP phone or a regular telephone connected to a VoIP adapter, the phone will ring like a traditional telephone. If your VoIP service requires you to make calls using your computer, the software supplied by your service provider will alert you when you have an incoming call.

In June the FCC imposed obligations on providers of interconnected VoIP services VoIP services that allow users generally to make calls to and receive calls from the regular telephone network. You should know, however, that calls using VoIP are handled differently than calls using your regular telephone service.

Please see our consumer fact sheet on VoIP and services for complete information on these differences. Aspects of these considerations may change with new developments in internet technology. You should always check with the VoIP service provider you choose to confirm any advantages and limitations to their service. For more information about VoIP see our factsheet pdf file.
