[asterisk-users] Voicemail post-processing

[Alex Balashov]

I would replace the call to Voicemail() with your own recording and 
generate a unique filename with a call to a script.  Use Record(). 
Then, when the message is done, call another script to rename the file 
to something that has a word like "COMPLETE" in the filename.

So, for example, assign recordings a name like VM-132456-timestamp.ulaw. 
  Then, when the recording is done, rename VM-123456-timestamp.ulaw to 
VM-123456-timestamp-COMPLETE.ulaw.  Have your script only catch that.

Be sure to catch a premature hangup event (while Record() is happening) 
with the 'h' extension.

Then call another script to attach and email the file to the right place.

It's sort of a kludgy hack, but it gets you what you want.
