Program to call a number and report changes in recording

I need someone to help me writing something that will call a phone number that always has a recording. It must identify if the recording has changed and notify me somehow (via email text message etc). I am open to ideas as to how the call will be made. It would hopefully be SIP based as I use Zopier right now.
