an ISDN based PBX for Linux
Formerly known as "PBX4Linux", Linux-Call-Router is not only a router, it is a real ISDN PBX which interconnects ISDN telephones and ISDN lines.
It is possible to connect telephones to a Linux box.
It is a pure software solution except for the ISDN cards and telephones.
The great benefit is the NT-mode that allows to connect telephones to an ISDN card.
Special cards are needed and a little bit of different cabeling.
It supports lots of features, that only expensive PBXs have.
It include a channel driver that can link LCR to Asterisk PBX.
LCR is open source and under GPL.
