I want to say it's B, but I might be mixing it up with another question about RTP and DTMF signaling.

I remember something about RFC2833 and DTMF, but I can't recall if it was related to OOB methods or H.245 signaling.

I think it might be A, but I'm not entirely sure about the specifics of flow-around versus flow-through calls.
