I have uploaded a new beta version (3.11beta) that supports some more script features. One of it is sending an email notification.
With that feature an answering machine with email notification is possible. 
When you open "Options/CLI" you will see a new button called "Example". At the moment only one example is available: voicemail!
So if you configure there some values and additional the settings at "Options/email" you will see a complete script. By right clicking into that generated script you can save it or save and activate. 
The saved script can be freely modified.
