The first place to look is to grep through the asterisk source code for
some PRI specific variables (like PRI_CAUSE). Follow its progress down
the stack. You should find yourself going from chan_zap (getting the
variable from the dialplan/channel, to pri.c, to q931.c, both of which
are in libpri. There's a model for how to do it. Have fun!
