Cloud Connector Edition Hybrid Voice Guide Version 2

Hi to all excited CloudPBX fans.

I finalized the Cloud Connector Edition Hybrid Voice Guide Version 2.
All important changes are covered and contains the full explanation of CCE Multi-Site Design, as well as how users must be configured.

Have fun reading it.


This guide is for Microsoft customers and partners, as well as vendors useful in the same (I promise ;) ).
It explains the entire technology and all related commands and cmslets.
Important is the Multi-Site CCE Design, which is most complex, but fully discovered and made open for your understanding.

A huge thanks the Westcon UCC, who allowed my spending a lot of time finishing this.
Therefore I'm very pleased in supporting the readers and try my best answering all question. You can contact me via my blog
