libmfcr2 - a library for MFC/R2 signaling on E1 lines

This library is designed to support MFC/R2 signalling in the ZapTel environment,
but should be easily adaptable to other dumb E1 cards that allow channelised
CAS signaled operation.

It is intended that the library eventually support most national variants of the
MFC/R2 protocol. The application specifies the national variant when opening a
channel.

*****WARNING*****

Don't expect too much right now. This software is very much at the alpha
stage right now. It doesn't support most national variants, proper protocol
error recovery, and various bells and whistles [I guess, the whistling part
must be OK, or the tone signalling wouldn't work at all :-)]. It probably
still has many bugs, since it hasn't been polished and debugged very much
right now.

*****On the brighter side*****

It can make and receive calls successfully when connected to a Dialogic E1
card running the GlobalCall 2.0 package, in China and Argentina modes.
