This read-create TruthValue enables or disables performing a DNS lookup to re-resolve the MGC's domain name after Max1 retries are exhausted without acknowledgement from a gateway-initiated message. It matters because if the MGC's IP address changed and DNS was updated, this re-resolution lets the gateway find it again instead of continuing to retry a stale address. For example, an admin who recently moved their call agent to a new IP behind the same hostname would ensure this object is set to true so gateways automatically pick up the new address after Max1 retries.
