I have been fighting with the Bayham Systems FastSMS AGI script, and I
re-wrote it as a stand alone Perl script.  I am now calling it with
the EXTERNNOTIFY option in the voicemail.conf file.  It gets passed
the context, extension and number of messages which I build into a
text, and since they all go to the same location its no problem.  I'm
planning on using the extension info to open the mailbox, and read the
text file for the latest message to pull out the caller for the text. 
I might also have an extension map in a text file so I can look up who
to notify about a VM.

This works after a fashion, and crucially is only triggered when
someone actually leaves a valid voice mail message.  It is limited in
the fact I can't pass any other system details than extn and context. 
Plus the voicemail count is wrong since the attach=yes|delete=yes has
already deleted the message when it counts them.

But it works.

Thanks for all the help and advice.
