Many people do not have any imagination about VoIP. The task of this article is to consider what is VoIP at all, its technologies, software and billing.

What is VoIP?

This abbreviation means Voice over Internet Protocol. VoIP technologies include different technologies that give us possibility to use IP networks for voice applications of various types. For example, it may be voice instant messaging, telephony, teleconferencing etc. Many software developers think that VoIP technologies have great future because it has different solutions almost in every level of IP network. It may be voice applications for specialized application, like Skype, which is one of the most popular VoIP software, or quality measures of the lowest levels that allow to run those applications in a smooth way.

There is also such utterance as VoIP billing. This is a new concept and its application will allow you to save a lot of money on paying of your telephone bills.

VoIP and its applications

As it was mentioned above VoIP technologies include different technologies that give us possibility to use IP networks for voice applications of various types. This applications may include the following: telephone services, desktop applications and phone systems of corporate type.
At first, telephone services. This is a service that will allow you to save money on telephone billing, it was named VoIP billing.

The next applications is desktop applications. This service was named VoIP software. It will allow you to use different software from voice-chat which was loaded on your PC desktop to IP-based telecommunications networks, such as Mac, which are used in large corporations.

Providers of IP service over voice usually use the internet to transfer voice signals from their own networks up to the phone located at your home. That is why their bills are much more cheaper that bills of other companies, because VoIP telecommunication is not organised in that way like traditional telecommunication phone lines.
What is expected for VoIP in the future?

One of the new VoIP technologies is cell-phones based on VoIP. It is almost ready for application. It will allow people to avoid interruption of communication driving your car, entering your office and then the signal will be transmitted to your laptop using Wi-Fi network. This type of technology is already existing but it is not widely used.

There are also a lot of different VoIP technologies which are not very widespread today. But it is expected the great future for them.

Voip service provider or Cable Companies Scramble For Their Piece Of Increasing Voip Market

Already branded as “Digital Phone,” cable companies are looking to grow existing direct thanks to VoIP services seeing more people are seeking cheaper ways to communicate. Technologies such thanks to SIP, short through Session Initiated treaty can establish sessions as features identical as audio/videoconferencing, interactive gaming, and call forwarding to substitute deployed over IP networks, thus enabling service providers to integrate basic IP telephony services with Web, e-mail, and chat services. With SIP protocols, MSOs will be useful to homogenize this technology to modern communique modems, enabling an easier transition to digital phone service. With the ever-increasing demand for communication alternatives, VoIP technology seems poised to emerge as the prop for the emerging digital phone circumgyration.

How-to Design a Voip Training Course

December 30th, 2009

VOIP Training and Education is gaining popularity as this vital technology is becoming an imperative to maintaining a competitive edge.

Designing any training course, the first aspect you have to consider is the answer that the training course will have to furnish to the demand of learning formulated by the buyer.

A non superficial knowledge of the training needs it allows to predispose a suitable and effective answer in terms of contents and, often, also of methods.

Besides it also allows to choose the teachers and trainers able to transfer knowledge to participants and also to manage processes.

From Were to Begin ? As for any other training intervention a plan of action is needed, what follows could be useful in our case:

1- Define Training Goals and Objectives:

Naturally the objectives of a training course on VOIP can be different according to the dimension of your firm and to your line of business.

For example if your firm is a small or medium enterprise that utilizes VOIP services as end user, the objectives of a training course on VOIP could be these:

-To make aware project managers and responsible of function persons of the necessity to adjust the organization to the technology Voice Over IP;

-To homogenize VOIP knowledge and skills among the business responsible launchings;

-To Identify the application problem list;

-To stimulate the dialogue among the persons responsible of function.

If your firm is a firm that supplies products, services and VOIP consultations, then the objectives could be:

To understand the market context and the perspectives of development of the VOIP products and services in your region or country.

To identify the technical and application problem list of the VOIP with reference specifically to the integration between traditional telephone infrastructures and IP networks of which it requires the client to safeguard the investments effected in the past.

Specific updating on necessary technical knowledge to effectively configure the customers VOIP equipments

Which is the Target Audience of a VOIP Training?

Here are some examples but this list is not exhaustive:

-IT managers

-Technical sales/marketing personnel

-Consultants

-Network designers and engineers

-Product design engineers developing integrated-services products

-Telecom technicians and managers integrating PBX services within data networks

-Systems administrators who will manage a converged network

2. Determine Participants’ Needs

In a VOIP training the initial demands of learning are usually the followings:

-Necessity to furnish the basics of VOIP technology to the participants, especially to those who are not technicians;

-To furnish a common language to all participants, both to those coming from Information Technology function that from the other areas not tightly tied up to the Information Technology (for instance administration, marketing, production);

-To facilitate the integration of the new technology with those existing;

-To appraise the impact of VOIP on the business structure and on the redefinition of the duties of the personnel;

-To understand the necessary elements to the determination of the ROI (Return On Investment) of the project of investment in the VOIP technology.

3. Outline Training Content

Here for example some hints:

-Introduction to Voice over IP

-Understanding the Requirements of Voice in an IP network

-Understanding Gateways and Their Roles

-Encapsulating Voice in IP Packets

-Calculating Bandwidth Requirements

-Understanding Security Implications

Voice over IP Signalling and Call Control

-Understanding the Need for Signals and Call Control

-Configuring H.323

-Configuring SIP

-Configuring MGCP

-Comparing Call Control Models

-Improving and Maintaining Voice Quality

-Comparing Voice Quality Measurement Standards

-Understanding VOIP Challenges

-Understanding QOS (Quality Of Services) and Good Design

-Understanding Jitter and Delay

-Understanding QOS Tools in the WAN (Wide Area Network)

-Configuring QOS in the WAN

-Understanding Voice Bandwidth Engineering

4. Develop Instructional Activities such as brainstorming, case studies, cooperative group work

Skill development is best achieved through modelling, practice, and feedback, while information acquisition can be achieved through group discussion or collaborative group work

Some strategies that promote active learning include brainstorming, games, mini-lectures, small group work, cooperative group work, simulations, role-playing, and VOIP implementation success case studies

5. Prepare Participant Evaluation Forms

The purpose of the evaluation is to determine the extent to which the training achieved its objectives and to identify what adjustments, if any, need to be made to the VOIP training design or follow-up process. Some issues to address through the evaluation form:

-Did the participants acquire the knowledge and skills that the VOIP training was supposed to provide?

-Were the trainers knowledgeable about VOIP training content?

-Were the activities interesting and effective?

-Was the training format appropriate?

-Is more training on this or related topics needed to support participants in their work?

6. Determine Follow-up Activities for the Event.

Without follow-up, the benefits of a VOIP training may quickly be forgotten or never used.

Follow-up activities provide the continued support and feedback necessary for the successful implementation of new ideas and practices.

To be effective, follow-up activities should be planned as you develop your VOIP training design, and should include a range of opportunities for participants to reflect on both the content of what they learned during the VOIP training and the process of implementation.
