I guess the answer is NO - "applications" are written in C and not 
scripted. Still you have verious options for configuration and scripting 
as Scott already pointed out.

Look here:

Depends on what exactly you need and when you want this to happen. One 
possible answer might be "HasNewVoicemail()":

Voicemail2 basically does this - you can configure it through 
voicemail.conf:
