Common mistakes.

- C. The protocol-specific configuration section of a device profile does not expose BFCP enablement controls; that setting belongs on the SIP profile.
- D. The SIP trunk security profile governs TLS and digest authentication parameters, not BFCP capability advertisement in SDP.
- E. There is no 'Allow BFCP Video Desktop Sharing' checkbox directly on the SIP trunk configuration page; the relevant control is in the SIP profile.
