Course Overview:

VoIP Training | Voice over IP Training Overview Course With hands-on Labs

VOIP training courses for Fortune 500 companies, small businesses and government agencies. It is not easy to master VoIP | Voice over IP. It’s a complex technology. The introduction and popularity of SIP means truly open system standards and options that are not vendor specific. Added to this, there are many deployment options available. Given this complexity, it’s no surprise that IT and telecom engineers find it hard to determine the optimum design and deployment choices for their environment. If you are a technical manager or professional, this VoIP Training course will help you understand the concepts, design considerations, and deployment models for VoIP. We will introduce you to the underlying protocols, compression methods, and network impact.

We will study the design considerations for distributed locations and remote/home workers. We will also study the physical and application layers regarding gateways, media servers, and endpoints. Planning and design exercises will help you make the bridge from the theory to the applications of VOIP. All in all, the VoIP Training | Voice over IP Training Overview course will help you acquire an in-depth understanding of the VoIP technology. You can turn this VoIP Training | Voice over IP Training Overview course into an Action Learning Workshop by extending it to three-days with the addition of a “workshop day” devoted to a case study specific to your organization. This applied learning day can help you learn while you build a VoIP design and procurement requirements document for your own organization.

Customize It:

• If you are familiar with some aspects of this VoIP Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the VoIP Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the VoIP Training course in manner understandable to lay audiences.
