There is so much information on the internet about SIP that is both hard to read and poorly presented making it difficult for people to learn about this most important protocol. So The SIP School with its lively, clear and fully animated eLearning program has become the only place you need to learn about SIP.

5 Running times for this program are approximate as the time will vary based on the student s own experience and of course, how much time they want to spend on the material and if they want to replay some modules. NOTE: Timings do not include the optional 13th WAN assessment module or additional Skype for Business material and labs. The time it takes to Play all of the slides and Videos (also known as the running time) plus complete all of the quizzes is = 13hours 33mins. The TOTAL time will be more than this and dependent on factors such as slides being replayed, note taking, working on Labs (some of which can take a few hours), also doing some extra work with the Software tools provided for the labs which we believe is a great idea as it increases student skills.

6 Further study time for the ssca and the taking of the ssca final test itself should also be accounted for. I s t h e r e a Pr e-r e q u i si t e t o t h i s p r o gr a m ? This program assumes the student has a good understanding of Data networking technologies along with the basics of Voice and Video over IP. This could be gained through long term working experience, other certifications such as Cisco s CCENT/CCNA/CCNP, even The SIP School s own Networking for VVoIP program also available via the website. Please check carefully as having the skills required will make the SIP learning experience a more productive one.
