There is a network connectivity issue or the far end node is out of service. | Check your system logs to determine to which node(s) you have lost IP trunk connectivity. Check your network connectivity between impacted nodes and confirm that the nodes are in service. Check your system logs to determine when the trunk went down. Check your audit logs for any IP trunk configuration changes. If a change has been made, return to the original configuration. Check your audit logs for any service maintenance commands. For example: Check if the IP trunk was forced busy by running the following maintenance command variance: BUSY BUSY XNET BUSY TRUNK Enter the following command to bring the IP trunk in service variance: RTS RTS XNET RTS TRUNK If the alarm is not resolved, collect required System Diagnostics logs and contact Mitel Product Support.
