To use Adhearsion you will need a few things:
Adhearsion 2 supports the following telephony engines:
Adhearsion requires Ruby version 1.9.2 or later. JRuby version 1.7.0 or later is also supported.
Most operating systems come with a version of Ruby installed. However, it is very important to check the version. Mac OS X ships with a version of Ruby based on 1.8.7, which is too old. Debian and its derivatives, including Ubuntu, provide a version of Ruby 1.9 with the package called ruby19.
One easy, cross-platform way to install an acceptable version of Ruby is to use the Ruby Version Manager, also called "RVM".
After you have RVM installed, installing Ruby 1.9.3 with RVM is easy:

If you prefer JRuby, RVM can also install JRuby:
