This is not open to dispute. Your second sentence has no subject and no verb either. All it consists of are two fragmentary present participle phrases ("waiting.."; "suffering..."). In the third sentence, the first clause ("the call resounds") works; the second clause is missing both a necessary conjunction ("and") and a non-optional auxiliary verb ("is") to make a correct passive.
But then, I'm sure you know better.
I certainly do.
And people lacking even a schoolboy's understanding of English grammar would be better off not posting in threads like this one.
