chan-capi (aka chan-capi-cm) for Asterisk

what is chan-capi?

ChanCapi is a module for the open source software PBX systems

to provide CAPI based ISDN/Telephony hardware support.

This module (often declared as 'driver', but it isn't) provides the connection between the PBX software and ISDN Hardware which provides a CAPI 2.0 compatible interface.

Older versions of this Cytronics & Melware provided chan-capi were named chan-capi-cm, but now it is just chan-capi from

source code
