[ale] telephony stuff

[gamyers at atlml1.atlprom.att.com]

I've recently gain some interest in telephony and was wondering if
anyone knows where I might look to find work that's been done in
this area for Linux.  Basically, I would like to be able to update
my voice mail message automagically.  I'm required to update it on
a daily basis and this is a pain.  In most cases it's the same
message with a date change.  It would be easy to create the
appropriate *.au files for all the dates, but I would need to better
understand how to send the appropriate keypad tones and such to get
to the proper prompt.  Is this possible?  Thanks for any suggestions,
pointers or directions.
