asterisk users - Oct 2006 - Recording from a script

Greetings,

I have been asked to provide a one off solution for someone. They would
like to take a message left on a remote voicemail system (with their
mobile phone provider) and get it to a wav/mp3 file. There is a number I
can call from my Asterisk system that would allow playback of the
message, but it would require sending some DTMF tones to do it
(traversal of the remote IVR on the voicemail system) I would then have
to record the resulting message (even if I can just use record() and get
it to GSM I can the transcode it to what I want).

In short I would like to know:
    a) if this is actually possible
    b) if anyone can give me some pointers on how I might go about      
       automating this with a script.

Thanks in advance.

My first shot at it would be
exten => getmsg,1,Monitor(wav,/tmp/msgdir/${UNIQUEID},m)
exten => getmsg,2,Dial(${VOICEMAILNUMBER}www${VOICEMAILDTMF})

I think there was an option for Dial() to hangup after some time
elapsed, but ideally you would detect end-of-voicemail tone if there is
one.
