Cisco IP Telephony Troubleshooting Guide for Cisco CallManager Release 3.0(1)

of partitions to which it is permitted to place calls — its partition search space. This provides for extremely powerful control over routing.

When a call is being placed, Digit Analysis attempts to resolve the dialed address only in those partitions that the partition search space specifies. Each partition name comprises a discrete subset of the global dial-able address space. From each listed partition, Digit Analysis retrieves the pattern that best matches the sequence of dialed digits. Then, from among the matching patterns, Digit Analysis chooses the best match. If two patterns equally match the sequence of dialed digits, Digit Analysis breaks the tie by selecting the pattern associated with the partition listed first in the partition search space (for more information, review the documentation about Closest-Match Routing).

Security

Cisco CallManager can be configured to create a secure dialing plan for users. This can be done through the use of partitions and calling search spaces, in addition to more common filtering based on sections of the "@" macro (which stands for the North American Numbering Plan) in a route pattern, such as the Area Code. Partitions and Calling Search Spaces are an integral part of security and are especially useful for multi-tenant environments and creating an individual user level. Filtering is a subset of the Calling Search Space/Partition concept that can add additional granularity to the security plan.

This is an extension to the Dial Plan section above. Be advised, usually the last thing you want to do when trying to fix a filtering problem is to run an SDI trace. There is simply not enough information and the potential for causing more harm is too great.

Run a "show tech" on Cisco CallManager. The following information appears in the Route Filter section.

Unfortunately the display is cut off. It does at least give a listing of all the Route Filters in the system. There is no way from the "show" command to see what filters are associated with which Route Pattern. Another way to get a handle on the dial plan is to go to the Route Plan Report page. Following is an option on the far right-hand side to "View In File".
