[Asterisk-Users] automatic voice dialout call

[Davide Giunchi]

I need to make automatic voice calls from a Linux server, so when the
system receive special "signals" it must use a wave (or .au) audio file,
dial the number to call a person, and "speak" using the audio file.
What can i use for this subject?
I need a specific hardware device or a normal analogic voice-modem is
ok? which software can i use (i need to invoke from a Perl script)? 

Regards
