Red x-mark - A trunking connection cannot be established between the ICPs and the SIP service providers.
Reason - If a trunking connection cannot be established, a reason for the failure is provided.
Calls in progress / Max - The number of calls currently in progress on the trunk, and the maximum number of calls that have been in progress on the trunk during the current session.
Calls per hour / Max - The number of calls processed per hour on the trunk, and the maximum number of calls that have been processed per hour on the trunk during the current session.
