It is problem related Calling search space. A calling search space comprises an ordered list of route partitions that are typically assigned to devices. Calling search spaces determine the partitions that calling devices search when they are attempting to complete a call. For more detailed information on calling search spaces and partitions, refer to "Partitions and Calling Search Spaces" in the Cisco CallManager System Guide.
