[cisco-voip] IPT QS: CSS and Partitioning

[William Roy]

By default, all Call Search Spaces (CSS) have the <NONE> partition at the end of the list of partitions (we can not see this in the configuration), so once you place a device in any parition other than <none> that new partition must be contained in the CSS of the calling device for a call to be made. If you were to put a route pattern in a partition of <none>, that would mean it is present in every CSS on the system and accessible from every device.

Forced Authorization Codes are applied to route patterns to apply a level of class of restritction, so if a user dials a route pattern that has a FAC on it, they must enter a PIN to be able to complete the call, i.e to be able to dial international you must have a PIN number assigned to you to be able to dial.

Client Matter Codes mark a call with a certain code so that a billing application can log calls made or recieved to a certain client, typically used by law firms that are billing customers for phone calls.

Wil

All,

I was reading CCM fundamentals 2nd edition and got confused on the following verdicts:

Partitions divide the set of all route patterns into subsets of equally reachable destinations. Equally reachable means that a user who can call any single member of the subset can call all members of the subset.

Then in subsequent paragraph the author says:

A partition is an attribute of an address. It belongs to called entities; it has no bearing on who a device can call. Membership in a partition does not automatically mean that a device can call other devices in the partition. The list of partitions in a device's calling search space is the sole dictator of who it can call.

Further,if we add devices to partitions other than NONE, the NONE partition device loose access to other device. Is this the case in opposite direction, that is visibility of route patterns in NONE partition to devices in partition other than NONE.

What is the difference b/w Force Authorization Code and Client Matter Codes. What I understood that CMC allow the ability for biliing and logging in CDR.

Need Clarification!

Regards,
Khalid
