I need to be able to monitor the extensions on a asterisk machine and be alerted to status change. If the go offline I want to be notified via email. Possibly have a spot to put in a specific message that is offline. I have a few of these and I would want to be notified something along the lines of "Ext 111 for ABC is offline" or Ext 111 for ABC is Online". Either the word online or registered is not a problem. Just so I can change it so I can install it on the couple I have.
