The case is that the a basic call is established, A and B are talking. A puts B 
on hold by sending offer with sendonly first, but B responds with inactive. B 
did not put A on hold first before receiving sendonly from A. This is kind 
weird, but rfc3264 says that it is valid.

"inactive" means the answerer does not desire to receive either.

This case will happen if both phones have put the call on hold.
