This OID sets the timeout (in seconds) after sending a Release message to disconnect; the first expiration triggers a resend, the second expiration forcibly closes the connection. Engineers rely on this to ensure proper call teardown and prevent ghost calls from consuming resources on failed disconnections. Example: 10 seconds means wait 10 seconds for release acknowledgment, resend the Release message, then force-close the connection at 20 seconds total if still unacknowledged.
