Question 1
Q1A support engineer is troubleshooting a reported issue where calls from a specific SIP entity are failing to route through the Avaya Aura Session Manager (SM). Upon checking the Session Manager Dashboard, the engineer notices the Entity Link status is 'down'.
Which of the following conditions would most likely cause the Entity Link to transition to a 'down' state while the network connectivity remains intact?
Show answer & explanation
Correct answer: A
Session Manager uses SIP OPTIONS messages to monitor the health of Entity Links. If SM sends OPTIONS requests and does not receive a 200 OK (or other acceptable response) within the configured timeout/retry limits, it marks the link as down, even if Layer 3 connectivity exists. This is a logic-layer health check.
