for several years, I deployed Cisco Video solution. but, many guide for deploying is not easy to understand.

basic concept is same for CUCM deployment. but important point, there is added Expressway for external video conferencing.

Expressway is require two DNS server and SSL Certification.

First, two split DNS server. one is isolated as caching server on internal network, the other one is open for public network.

It's the way to communicate each VM infrastructures and make traffic efficiency.

Second, SSL Certification is way to protect communication exposed on internet.

you can buy SSL Certification for UC at verisign or symantec. or you can make Self-Sign SSL Certification using OpenSSL.

deployment is not difficult following the cisco documentation.

Good luck.
