Cisco CallManager - Tandberg mx6000 or 95 Video Bridge integration Review

We are reviewing options to use 2nd hand hardware/solutions to provide video calls between our users. We currently have: Cisco Unified CM Administration/System version: 7.1.5.10000-12 Cisco Unity Connection Administration/Version 2.1.3ES23.1000-23 This project is to evaluate what products can be used that can potentially integrate into the CallManager or if other solutions are available. The solution must meet "corporate" high standards with as little problems/ease of use. To be able to take on this project, you must have experience with CallManager / Video conference integration. This is part one of two projects. Part one, as described above to evaluate solutions, provide an "executive report" with recommendations. Part two is to implement this solution and put the service into production.
