CapiSuite is an ISDN telecommunication suite providing easy to use
telecommunication functions which can be controlled from Python
scripts. Currently, mainly voice functions and fax sending/receiving
are supported.

It uses a CAPI-compatible driver for accessing the ISDN-hardware, so
you'll need an Eicon or AVM card with the according driver.

CapiSuite is distributed with scripts providing a multi user answering
machine with automatic fax recognition, remote inquiry and fax
send/receive functions.
