Explanation

{"question_number": 8, "question": "Which two features must be enabled on SIP security profiles when integrating Unity Connection with UCM using SIP?", "correct_answer": "D. Accept replaces header and E. Accept unsolicited notification", "explanation": "Two SIP security profile settings are critical for CUC-UCM SIP integration. 'Accept replaces header' enables UCM to process SIP REPLACES headers, which Unity Connection uses during supervised call transfers (e.g., transferring a caller mid-greeting to a live extension). 'Accept unsolicited notification' allows UCM to accept SIP NOTIFY messages that Unity Connection sends unsolicited - this is required for Message Waiting Indicator (MWI) updates (the lamp/stutter-tone on phones). Without these two settings, transfer and MWI features fail. Options A, B, and C relate to presence, authorization, and billing headers not required for standard CUC integration.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
