The 'status' field is the status of the campaign from the TCR perspective. The 'mnoStatusList' field, is a list of statuses from the individual carrier perspective. Both sets of statuses are entirely independent. It is possible to have a campaign that is in 'ACTIVE' status from the TCR perspective, but have 'REJECTED' statuses from one or more carriers.
At this point, the carriers campaign review rules are unknown to Bandwidth. To get your campaign re-reviewed, you will have to update your campaign and re-submit.
