Search in asterisk log

I wish to be able to search the asterisk log to see how many calls, which comes into queue 1234, which has been answered and how many, which has not been answered, can you help me with what we must grep/search for?



Can I be sure that ABANDON is calls, which has not had any connection? Can se that some are called:


Is it because it has been hung up afther permand has answered, but before the call went through
