Quick Enroll    

You Will Learn How To
  • Obtain the maximum benefit from Voice over IP (VoIP) and voice/data integration
  • Identify the costs, benefits and challenges of VoIP in multivendor networks
  • Interpret H.323, SIP and other industry standards for VoIP
  • Apply signaling techniques for packet voice services
  • Engineer high Quality-of-Service VoIP networks
  • Design networks to carry mixed voice and data traffic

Course Benefits
Voice over IP reduces your telephony costs and provides unique opportunities for integrating voice and data. In this course, you gain the knowledge to use a data packet network to provide wide area voice communications. You learn how to ensure Quality of Service for VoIP traffic and how to take advantage of VoIP for new and innovative applications.

Who Should Attend
Anyone interested in migrating voice traffic to new or existing data networks. A basic understanding of TCP/IP internetworking and telephony concepts at the level of Course 373, "Telecommunications Introduction," is assumed.

Hands-On Training
A series of exercises provides you with practical experience in key aspects of Voice over IP technology. Exercises include:
  • Making calls with H.323 and SIP protocols
  • Measuring the effect of codecs on network bandwidth consumption
  • Calculating the degradation in voice quality due to packet loss, delay and jitter
  • Capturing network traffic
  • Engineering a network to carry VoIP using Erlang charts
  • Configuring IP phones and gateways
