About this task
There’s more to removing a trunk group than just executing the remove trunk-group command. If you’re using Automatic Route Selection (ARS), you must remove an outgoing or two-way trunk group from any route patterns that use it. If you’ve administered Trunk-Group Night Service buttons for the trunk group on any telephones, those buttons must be removed or assigned to another trunk group.
As an example, we will remove trunk group 5. This two-way group is used in ARS route pattern 2. In addition, a Trunk-Group Night Service button on extension 8410 points to this group.
