A cheap solution would be to take a PC or embedded device with a
network card and a passive ISDN card running Asterisk
(http://www.asterisk.org) on top of Linux (there are even Debian
packages). That way you can manage extensive dialplans,
fax/voice2mail/boxes, ...

A asterisk (www.asterisk.org) on a PC with Linux OS and a ISDN PCI card that
are supported by asterisk (example Eicon).

There is active ISDN cards witch has processing onboard the ISDN card =
expencive and then you have passive cards with less processing onboard the
ISDN card and those card uses more CPU capacity from the motherboard and are
less expensive.

Pick a card that has support from the ISDN4LINUX (www.isdn4linux.org).

Check the link http://www.isdn4linux.de/faq/i4lfaq-5.html#ss5.1 for hardware
support and http://www.isdn4linux.de/faq/i4lfaq-5.html#ss5.2 for an
explanation of the difference between active and passive ISDN card.

If you want to spend 600$, 70$/year and 6 hours for the basic
configuration you should take a Cisco 7960G! ;-)

If you want a cheap (70 -100 $) but reliable solution, you should take
the Grandstream ATA-286 analogue adapter and a good analogue phone. Do
not take one of Grandstream's BT-100 series phones! They have no
address book and the micro of the speaker phone isn't worth it's name.
