Asterisk recepie for Ubuntu

This guide will show how to install a small asterisk PBX in the cloud on a VPS that you and your friends can use to call each other for free using SIP applications on Android, Iphone and Ipad. I have tested this configuration with Sipdroid(Android) and Acrobits Softphone(Iphone,Ipad).

$ sudo apt-get install puppet

file asterisk.pp, please change node name styx to your hostname, please change secrets

class asterisk

package { "asterisk": ensure => installed }

$ sudo service asterisk restart
