Amardeep -
    Is this SMSC running SMPP?  There are, I believe, interface stacks  
for SMPP that are available as open source.  If you can cobble  
something together on a command line that does what you want, the  
current voicemail implementations may be able to execute a command  
with the appropriate settings, as Leif mentions.  However, you would  
need to get an SMPP client running as a third-party application.

    Alternately, does your provider support SMS via SIP INFO  
messages?  I talked with someone as recently as today (Hi, D!) who  
might be interested in committing the patches for that particular  
method, but it depends on your vendor supporting that SMS transmission  
protocol.
