When a call encounters a busy vector command in vector processing

When a Direct-Agent call tries to terminate an on-ECS ACD agent and the specified ACD agent’s split queue is full and the specified ACD agent does not have coverage

When a trunk is maintenance or administration busy, or the administration on two sides of the trunk is not the same (CS0/6)
