Nope, this is the correct version.  It reads "If this is NOT a zombine AND
it hasn't been hungup THEN call on the channel".

Can you get a backtrace?  It's hard to imagine a situation in which we
would dial on a zombie.  Clearly ast_call would return -1, but there may
be a crash buried somewhere else.
