I guess you mean: carry on if it happened (and don't care any more).

It seems that making some calls makes these error messages go away. I am going to write a test 
script that monitors the log file for the message and triggers a call if one occurs. Then I'll 
see whether my hypothesis is correct.

It doesn't happen all the time, though. I have skimmed, but not studied, the Q.921 ITU specs 
already, and for synchronization it may be necessary that libpri is active (essentially getting 
* to run ASAP after starting the machine) and that just starting the driver (wanrouter in my 
case) is not sufficient to sync the cards. I have to test this, but the idea is that letting the 
cards communicate without some higher level support from libpri may be responsible for the error 
condition.

I'll keep watching for whatever might trigger the error condition.
