Explanation
{"question_number": 5, "correct_answer": "A", "explanation": "An outbound PSTN number translation rule rewrites the dialed number before it is sent out to the PSTN via the SBC. To route calls dialed as 9911 to the actual emergency number 911, a translation rule is configured to strip the leading 9 from the number before it reaches the carrier. A dial plan normalization rule (B) converts locally dialed formats to E.164 (+1911) but is not specifically designed for this outbound PSTN digit manipulation. An emergency call routing policy (C) defines which numbers are treated as emergency calls and which PSTN usage they use, not digit rewriting. An emergency calling policy (D) controls who is notified when an emergency call is placed.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
