| Intended audience: |
This course is valuable for anyone interested in the migration of voice traffic to new or existing data networks : project managers, technical sales, customer configuration analysts, help desk technicians (level 1), technical staff (level 1), IP network and VPN providers, telcos, hardware and infrastructure manufacturers, IT professionals and consultants. |
| Objectives: |
With the ever increasing market acceptance and deployment of VoIP solutions it is now critical for organisations to understand the benefits, challenges and skills required to successfully deploy this vital new technology. Voice over IP has been proven to reduce telephony costs and provide unique opportunities for integrating voice and data and by completing this course participants will be able to:
| a) |
Understand how to use a data packet network to provide wide area voice communications |
| b) |
Understand the role of each component of the network |
| c) |
Understand the transmission process of a voice signal over an IP network |
| d) |
Discuss the challenges related to the convergence of voice and data networks |
| e) |
Identify critical issues to consider in the planning stages of the implementation of a VoIP network |

| Delivery method: |
This course uses a different and more innovative approach than traditional training. Very interactively, the instructor will first explain the basic concepts and notions. Then, participants will simulate, as if they were within the components of an IP phone network, various steps of a voice call over an IP network. Based on the observations made during the simulation, the instructor will then crystallise the theory. |
| Deliverer: |
Member(s) of the Argilon training team. |
| Duration: |
2 days. |
| Pre-requisites: |
The participant should have a basic understanding of IP networks. |
