To block a call based on calling number (ANI):

Busy Weekend in the Lab
Started the weekend off with an 8 hour rack session from CCBootcamp. I had previously purchased several sessions and have decided to use these and save most of my Proctor Labs sessions for when I work through IPexpert’s workbooks Volumes 2 and 3. I spent the first 30 minutes or so making [...]

Cisco - Config Archive Variables
I was browsing videos on brainbump.net last Friday and noticed a different take on a tutorial I did regarding automatic configuration backups with the ‘archive’ command. While watching the video, I learned a new trick. The file name in the ‘path’ command may contain two different variables.

Testing Cisco Survivable Remote Site Telephony (SRST)
A fast and easy way to test your SRST configuration without taking down the WAN interface, is to add a static route to null 0 for any ip packets coming from the network the Callmanagers are on.
This will cause phones to lose contact with all callmanagers and go into Fallback mode, while still preserving data [...]

For those of you wondering, I will continue to [...]

If you have used GNS3 for any amount of time at all, you have encountered this situation. It’s late and you have been working on your lastest lab for hours. You decide to save your work. Logically, you go to File > Save. Unfortunately, the topology is saved but the router configs are gone. [...]
How to change the MAC address on a Call Manager 5/6 Server
After releasing the video tutorial for installing Call Manager 5/6 in VMWare, I received a comment asking how to change the MAC address on the Virtual server.
