3.2.
External Call Block
If multiple tenants are using the PBX, the External Call Block feature should be programmed to
control which COS numbers are allowed to access which trunk groups. By preventing certain COS
numbers from accessing certain trunk groups, each tenant can be given its own trunk groups which
no other tenant can access.
[Programming Example: External Call Block]
COS
COS 1
COS 2
COS 3
COS 4
COS 5
COS 6
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.
