Networking 4 Voice and Video over IP (VVoIP)Course ObjectivesThis course will give students a good understanding of LANs, WANs and VVoIP(Voice and Video over IP).It is aimed at those who want to move into the world of VVoIP and require a solidfoundation before attending any manufacturer or service providers own systemscourses. It can be taken as a standalone course and also used as a foundation forThe SIP School’s SSCA ‘Elite’ SIP training program.Being a modular training course, students can work through all modules or simplychoose the module they really need.‘Timings’ are shown in the document though these can vary greatly depending onthe existing skill levels of each student and should be treated as a ‘rough guide’.The ‘average’ time to complete the course and take the SSVVP certification test is(approx.) 13 hours. You will notice each module (when running) shows a ‘modulelength’ timer. This is a shorter time as shown in this document as the ‘timer’ doesnot include student’s lab and quiz work.Most modules have their own ‘mini’ quiz at the end to help students ‘gauge’ how wellthey are doing and the ‘Final’ SSVVP accreditation test is available from thedelegates own ‘Course’ list page on the main site when logged in. NOTE: Topics in Blue are new additions/updates from January 2020The Modules are detailed on the following pages:
