PLEASE READ CAREFULLY
This PDF may help you make notes as you work through the online course. It is
provided 'as is' and is only for use by the student who downloads it. Please see the
header of each page.
Slides may not fully represent what you see on the online training (in fact some
slides are blank where quizzes and other animated elements and embedded
webpages should be) and again, this PDF is an 'aid' not a replacement for the online
material. Images are not of the same quality as seen online due to PDF compression
settings
The 'principle' of the online material is that as SIP evolves, so does the online
material. Consequently, a PDF you download today may not reflect what's on the
screen tomorrow.
This PDF is not for distribution of any kind and is protected by copyright for Vocale
Ltd, the owner of The SIP School. Distribution of any kind will result in your logon
being revoked plus any additional action that Vocale Ltd deems necessary. 1
