Restricting Communications With Partitions and Calling Search Spaces Within CUCM

Being able to restrict telephony services, specifically who can call who, is an important function for voice engineers. For instance, voice engineers may want to restrict things like international calling, being able to dial a CEO directly, or calling 900 numbers. Two of the tools used to accomplish that within CUCM are Partitions and Calling Search Spaces.

Partitions are like containers. They group things like directory numbers, translation patterns, route patterns, etc…

Calling Search Spaces are groups of partitions. Partitions are assigned to Calling Search Spaces. Calling is then restricted to partitions in that search space. Due to this, voice engineers will need to model and create Partitions before Calling Search Spaces are created.

Another way to look at it is as Partitions control who you can call versus Calling Search Spaces that define who can call me.

By using Partitions and Calling Search Spaces with CUCM, voice engineers provide a way of calling permissions for who can call who.
