state.
Description
The problem can happen on any integration type and on any model gateway. On the
gateway’s “Network Configuration” screen if DNS is configured to non-default settings
(IP address or DHCP for the DNS Server, domain name for the DNS Domain), the
gateway may experience the reset/lockup problem. An affected gateway may
experience either one or both of these symptoms (reboot and lockup).

During a reboot, phones assigned to the affected gateway would show “No GW
Response” for a minute or two while the gateway is resetting. Reboots may also be
indicated by unexpectedly shorter uptimes on the affected gateways compared to
uptimes on unaffected gateways which remain running on the same system.

uptimes on unaffected gateways which remain running on the same system.
On a gateway lockup, users would experience loss of phone service on phones
assigned to the affected gateway. Once a gateway locks up, the other gateways can no
longer “see” the locked up gateway (it disappears from the list of system gateways on
the “Gateway Connection Selection” screen). The gateway will remain in the locked up
state until a manual reboot is done to temporarily clear the problem.
