VoIP

( Duration: 2 Days )

This VoIP training course provides skills to plan, architect, design, engineer, test, verify and validate, integrate, manage, and administer voice and data communication applications. The Voice over IP (VoIP), which integrates voice and data transmission, is quickly becoming an important factor in network communications. It promises lower operational costs, greater flexibility, and a variety of enhanced applications. This course provides a thorough introduction to this new technology to help experts in both the data and telephone industries plan for the new networks.

By attending VoIP workshop, delegates will learn to:

  • Explain the basics of telephony and TCP/IP
