[Programming Example: Internal Call Block]
In this example:
Internal Call Block is employed to block calls between certain tenants.
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 make calls to extensions in Tenants
1, 2, and 3.
b) Extensions in Tenant 2 are either COS 3 or 4. They can make calls to extensions in Tenants
1 and 2, but not 3.
c) Extensions in Tenant 3 are either COS 5 or 6. They can make calls to other extensions in
Tenant 3 only.
