Summary:                    Call that clears in same app_dial poll as answer is
reported as NOANSWER but NORMAL_CLEARING
Description: 
If a call clears so fast after being answered that app_dial fails to read a
frame before it realises it has been answered, handle_cause breaks from its
switch and does not increment any of its failure reason counters.  The call
ends up with a "No one is available to answer at this time (1:0/0/0)"
message logged, the default DIALSTATUS of NOANSWER and a HANGUPCAUSE of 16
(AST_CAUSE_NORMAL_CLEARING).

If it clears just slightly later, it is treated as a successful, if short
call (that's why it is "sometimes", not "always".

The variablility in the result, depending on precise timing is confusing,
and NOANSWER does not seem an appropriate status.
