Fast start-to-early media scenarios refer to situations where two endpoints establish media connections and begin transmitting audio or video before the call signaling is fully completed. This allows for a faster call setup time and improved user experience.

When H.323 and SIP protocols are used together for interworking, extended capabilities must be configured on the dial peers to support fast start-to-early media scenarios. Two of these extended capabilities are:

  1. BFCP (Binary Floor Control Protocol) - This protocol is used for controlling floor control permissions in video conferencing environments. It allows users to share control of a conference floor and pass control to other participants. BFCP is used to negotiate and control video sessions.

  2. AUDIO - This capability enables early media for audio streams, allowing audio to be transmitted even before the call is established. This allows users to hear ringback tones or announcements while waiting for the call to be connected.

Therefore, options B (BFCP) and E (AUDIO) are the correct answers to this question. Options A (DTMF), C (VIDEO), and D (FAX) are not required for fast start-to-early media scenarios in H.323 to SIP interworking.
