Present Perfect Continous or Present Continous

Hi, I'd like to know whether the following sentences are both correct;

I've been phoning the hospital all morning but they aren't answering.

I've been phoning the hospital all morning but the haven't been answering.

Thank you.

The second sentence sounds unnatural to me, but I can't tell you if it's incorrect for sure.

Thanks a million for your reply.
