How To: Install Asterisk 1.6.2.x with Dahdi on CentOS 5.5 Cloud Server (Slicehost or Rackspace) Tutorial
I recently built an asterisk test machine on a rackspace cloud server to see if it would work and how well it works. I haven’t concluded my testing but up to now it seems to be working as if it were installed on a dedicated server. I am actually really impressed with the way the cloud servers work, it is so easy to add a new server to your inventory and then you can use it for whatever you want. The problem with running in a xen cloud environment is zaptel dummy and dahdi dummy will not work, this has something to do with the way the hardware is visualized. This in turn can cause problems with meetme and therefore I cannot say for sure how well asterisk will work on a slicehost and rackspace cloud server, or any other voip application for that matter since voip relies on hardware timers. With this tutorial at least you will be able to install asterisk and see how it works for your application in a cloud enviroment, please be sure to post comments if you do use this and how well it works. Note this will only work for kernel version 220.127.116.11, if you have a different kernel you need to adjust this install.
