I've added code to zaptel.c, I think the issue is at a lower level than the
PRI code.

Do you have a pointer to a good reference document for PRI Q.921/Q.931, I
need to understand the flows and states?

If your adding code to libpri to do this, please use the facility that I
already made available.  Uncomment the LIBPRI_COUNTERS line in
libpri/Makefile then add the code to display the info to
pri.c:pri_dump_info()
