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 CO line groups. By preventing certain
COS numbers from accessing certain CO line groups, each tenant can be given its own CO line
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 CO line 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 CO line groups 1 and 2.
b)
Extensions in Tenant 2 are either COS 3 or 4. They can access CO line groups 3 and 4.
c)
Extensions in Tenant 3 are either COS 5 or 6. They can access CO line groups 5 and 6.
