Class of Control question -CUCM

A calling Search Space (CSS) is a top-down ordered list of route partitions. Can someone explain what is the benefit of making partition on top. Thanks

Hi

The first thing to understand is that routing on CUCM is done by best match - so if you dial 1234, and there are two route patterns available (e.g. 12xx and 123x) then it will match the 123x route pattern.

The partition order in a CSS is there as a tie breaker. So:

- It is not possible to add two identical patterns/DNs to the same partition. The two examples above (12xx and 123x) are different, so could go in a single partition. However - you could not add 123x twice to the same partition.

- If the same pattern/DN exists in two partitions, then the order within the CSS breaks the tie. the highest order partition is where the call is routed.

Is there any relationship between Phone line CCS and Route Pattern's route partition ?

You can dial things that are in a partition that is part of the calling device's CSS.

The calling device's CSS has two parts - the device CSS, and the line CSS. The two are added together, so you get the cumulative total of the two.
