ISDN answering machine, client

 Let your debian system be your answering machine! Messages can be accessed
 remotely, automatically emailed, etc.
 .
 This is the client part of the software, with which you can listen to the
 messages. Those messages are recorded on a system with the server part of
 the software (isdnvboxserver); that system may be elsewhere, as long as
 it can be connected to via a network.
