c) Blocking trunk calls made through another PBX and how to override it:
Whether an incoming TIE line call can make a trunk call through this PBX (i.e., PBX-2),
depends on the COS that is assigned to the trunk group of this PBX, that the incoming TIE line
is connected to. If the COS of the trunk group is unable to make outgoing calls by the Toll
Restriction/Barring feature or External Call Block feature, trunk calls made through this PBX
will be prohibited.
To override this prohibition, an extension of PBX-1 must enter a verification code assigned to
PBX-2 to change the COS temporarily. It is also possible to override the prohibition by
specifying an extension at PBX-2 with the Walking COS feature, to temporarily switch to that
extension's COS.
