View course dates

Course Duration: 2 Days

Course Code: 0365C

Course Description:

This 2 day Instructor led course is designed for design and support specialists with a working knowledge of voice and data who need the fundamentals of Voice over IP technologies.

 

At the end of the course, delegates will be able to:

• Define the key infrastructure considerations to support the addition of VoIP traffic in a Local Area Network, Wide Area Network, and Wireless environments
  
• Apply knowledge of how voice is sampled and converted into IP packets to determine the appropriate CODEC and packetization interval required to meet customer VoIP bandwidth requirements
  
• Compare and contrast transport models, such as Voice over IP, Voice over Frame Relay, and Voice over AT
  
• Describe standard voice quality measurement models, such as the Mean Opinion Score and the E-Model
  
• Apply knowledge of the attributes of Real-Time Protocol to identify why it is ideal for handling packetized voice in an IP telephony environment
  
• Compare the unique attributes of User Datagram Protocol and Transmission Control Protocol 
  
• Choose the appropriate CODEC given customer bandwidth and voice quality performance requirements
  
• Determine bandwidth requirements based upon call volume and CODEC selection
  
• Choose the appropriate method to implement Quality of Service given customer voice quality requirements
