In this example:
External Call Block is employed to prevent tenants from accessing all trunk groups except the ones
designated to them. Each extension in a tenant is assigned a COS that is not assigned to extensions which
belong to another tenant.
a. Extensions in Tenant 1 are either COS 1 or 2. They can access trunk groups 1 and 2.
b. Extensions in Tenant 2 are either COS 3 or 4. They can access trunk groups 3 and 4.
c. Extensions in Tenant 3 are either COS 5 or 6. They can access trunk groups 5 and 6.
