Programmable Answering Machine Software? [closed]

"What I think may be what you need:

Kphonecenter:

This is an application inspired by
Rapidcom Voice for Windows. It is an
app that lets you use a voice modem as
an answering machine,and a Fax. I also
plan to let it act as a dialup shell
account.

The reason I started this project is
because

1: I hated running Window$,
and wanted to move off of it. 2: I
wanted something that was a little
more flexable and feature rich.
Something that could grow to meet
anyone's needs. So I started this
project. I visioned it running on some
sort of embedded device on the wall in
your house someday. Walk in, tap the
screen, listen to your messages. Even
talk on the phone while cooking Ziti

IVAM2 0.3:

ivam2 is an automatic phone answering machine software for ISDN and Linux. It is the completely rewritten successor of ivam featuring many additions.

ivam2 is seperated in two parts: the core daemon written in C and the automate logic coded in Python. The latter is pluggable and may be replaced by different implementations on a per phone number basis (both caller and callee). This makes ivam2 a very powerful application server for telephony services. The software is very scalable, multiple ISDN channels may be controlled from a single daemon. To write telephony applications for ivam2 is not complicated. In fact, they are simple executables which read audio data of the caller from STDIN and write audio data for the caller to STDOUT. DTMF sequences may be read from a FIFO special file. A framework for writing telephony applications in Python is provided, a simple answering machine script based on this framework as well. You are free to write applications in other languages such as Perl or C."
