Hi Guys, 

I would like know what is difference between to configure Calling Search Space on Phone Configuration and Directory Number Configuration.

Thanks,

Wilson

The only difference is the order they are processed. If you have a CSS set on both the DN and the device the combination of both, with the partitions in the DN CSS placed first then the partitions from the device CSS, is going to be the effective CSS used for call processing.
