Resolved: Interruption with voice services
Inbound and outbound voice traffic is routing successfully and there was no impact to voice services when the maintenance work was implemented. Voice services are now operating in a fully redundant mode.
ITS has some minor maintenance work that will be performed early next week during a scheduled maintenance window. ITS will continue to monitor status of the system.
