Recently i was asked by one of blog follower a question – “How to differentiate between a CUCM Restricted version and CUCM Unrestricted version”?

This post is dedicated to the new Cisco Voice Techies who want to know how to differentiate.

Here is the difference between Unrestricted CUCM and Restricted CUCM:

Restricted version of CUCM has encryption enabled whereas Unrestricted version of CUCM does not have encryption enabled. Unrestricted version of CUCM does not provide signalling and media encryption. Once the unrestricted version of CUCM is installed, it cannot be converted into restricted version of CUCM.
