Partitions and Calling search Spaces

Partitions and Calling search Spaces

Partitions: Groups of dialable numbers
-Lines
-Route Patterns
-Anything that has a number

Calling Search Spaces (CSS): A list of Reachable Partitions
-Assigned to any ‘dialing’ entity
-Defines calling priviliges

By default all numbers are assigned to the [none] partition
By default all devices are assigned to the [none] CSS

This default allows everyone to call everyone by default

Practical Setup:

Three types of calling restriction should exist in your

organization:
– Lobby/Public phones: internal extensions only
– Typical users: internal and local pstn
– Management: internal, local, and long distance pstn

Step 1: Creat the Partitions
Step 2: Assign numbers to partitions
Step 3: Create CSSs
Step 4: Assign CSSs to devices

EXAMPLE CSS and Partitions:
INT_CSS
-Internal_PT

LOCAL_PSTN_CSS
-Internal_PT
-Local_PSTN_PT

LD_PSTN_CSS
-Internal_PT
-Local_PSTN_PT
-LD_PSTN_PT
