Cisco – Multisite Single Cluster Call Manager 4.1 Design
On the heels of my CIPT test (call manager test), I’ve completely redesigned from the ground up our call manager configuration. I’ve changed the way the system works pretty much completely…hehe. I spent a good bit of time putting together the Visio, so I figured I would share it with you guys, and also explain…

Cisco – IPSec Tunnel Termination via HSRP

Using Asterisk as a Conference Bridge for Your Cisco CallManager
This is using Trixbox as a web scheduled conference bridge for your Cisco Callmanager. As most of you CCM guys know, CCM comes with a light meet-me conference bridge; you can’t password protect in any way and there are few features. If you want to run the Callmanager conference server, you are looking at somewhere…
