Call Blocking
Through Class of Service (COS) programming, it is possible to:
1.
Prevent extensions of one tenant from calling extensions of another tenant. (Tenant-to-Tenant
Call Block)
2.
Limit the trunk groups which can be used by the extensions of each tenant. (External Call
Block)
3.1.
Tenant-to-Tenant Call Block
Using Internal Call Block, certain features, such as making intercom calls, can be restricted based
on the COS assigned to extensions. (
→
1.9.14 Internal Call Block) Well-planned COS
programming can prevent extensions of one tenant from:
– Calling an extension or doorphone which belongs to another tenant
– Picking up calls ringing at extensions belonging to another tenant (
→
1.3.6 Call Pickup)
– Retrieving calls being held by another tenant (
→
1.3.2 Call Hold)
[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.
