Using modem for sending voice recording

Linux uses vgetty for voice data over a modem (mostly as an answering machine). It looks like there's a perl module over at CPAN that comes with an example script like what you want.

Callme script

In the examples subdirectory of the source distribution there is a callme.pl script. This dials the given number and plays the given message. Use the following command to run it:

    vm shell -S /usr/bin/perl callme.pl <number> <message>.rmd

I use an external server for running an additional instance of Nagios, which is a last resort notification in case of complete failure.

I wish I had an answer for your modem audio playback question. I want to say it should be simple but my knowledge of that stuff is getting rusty. There used to be Voice Modems sold specifically for playback of audio.

If I were you, I would be trying to redirect audio playback using console software. I'd think this could be very simple. I might research more later when I have a moment.
