Voice Over Internet Protocol, IT-O 546

About this Course: 

This course covers a suite of application protocols known as Voice over IP (VoIP). It describes important protocols within that suite including RTP, SDP, MGCP, and SIP and the architecture of various VoIP installations including on-net to on-net, on-net to PSTN and Inter-domain scenarios. The functions of the Network Elements that play significant roles in this architecture will be defined. Examples of network elements that are currently available as products will be examined.

Course Status: 

In progress

Prerequisites: 

IT-O 440 Network+ Certification Training, OSI Model Networking and protocol concepts or equivalent experience required for enrollment.

Who Should Attend: 

This course is valuable for anyone interested in migrating voice traffic to new or existing data networks, including datacomm and telecom professionals, network managers and administrators, mobile network managers and administrators, mobile network designers, project leaders and consultants.

Expected Outcomes: 

Upon completion of this course, participants should be able to:

  • Use protocol analysis tools to analyze the message flows between Session Initiation Protocol (SIP) functional elements
  • Draw message sequence charts to aid in the analysis
  • Identify the header fields and parameters that may change as the messages traverse the network
  • Verify correct behavior and isolate trouble in the analysis
  • Identify the media streams and signaling messages associated with a Session Initiation Protocol (SIP) call and will be able to analyze the contents of both
