Unknown error 500 is an ELAST return code from zaptel driver.
It is telling libpri that there is an event in the queue.
If the read/write routines see that there is an event in the queue,
it just returns ELAST.  Libpri needs to do an ZT_GETEVENT to clear the event
and should do some error handling if needed.
