Overview
This feature is an attempt to create a grouping
mechanism for Unity Connection that maps to CUCM's
call search space and route partition features.
CUCM object to corresponding CUC object:
 route partition -> partition
 call search space -> search space

Partitions:
 Addressable objects are assigned to a primary partition. The
primary partition contains the object and the objects primary
extension.
 Subscribers can also have alternate extensions in other partitions
called alternate partitions. The alternate partition contains the
subscriber and the subscribers alternate extension.
 When an object is created it is assigned to the search space and
partition of the template if one is used or the system default
settings when a template wasn’t used.
 Alternate extensions are always create in the primary partition of
the subscriber, but the administrator can move them to a different
partition.
 All the extensions within a partition must be unique.

Search Space usage:
 Search spaces limit the objects that a caller or logged in subscriber
can see in the system.
 The search space’s partition order is used in a numeric search to
decided on a single, unique match.
 These objects have search spaces: Subscribers, Directory
Handlers, Call Handlers, VPIM Locations, Subscriber Templates,
and System Call Handler Templates.

Searches using Search Spaces
 When Unity Connection searches for an extension, caller id, or
forwarding id it looks through the search space's partition list in
order until it finds a primary or alternate extension that matches.
 When Unity Connection performs other types of searches it returns
all objects that are in the search space's partition list that match the
search criteria.

Search space of the call concept:
 Each call is assigned a search space by the routing rule. These
search spaces are used when matching the caller/forwarding ID to
a subscriber, when a caller tries to sign in, or when a caller enters
an extension in a call handler.
 The search space of the call is changed when the caller hits a call
handler with a different search space. The search space of the call
can only be changed by a routing rule or a call handler. The
search space of the call is not changed when a user logs in or a
directory handler with a different search space is used.

Subscribers and Search Spaces
While a subscriber is logged into either the TUI, VUI and CPCA, all
searches that a subscriber does use the subscribers search space.
The subscribers search space is also used when searching for
recipients while a message is delivered. If the recipient isn’t in the
search space an NDR is created. During message deliver, we only
check the search space membership of top level recipients. We
don’t check each member of a distribution list.

Handlers and Search Spaces
 Directory handlers can be configured to use either the call’s search
space or a specific search space to scope its searches.
 Call Handlers can be configured to either change the search space
of the call, or inherit the calls search space. The search space of
the call is used in the call handler when doing extension based
searches or signing in.

Other objects and Search Spaces
 VPIM Locations: A VPIM locations search space is used for
matching incoming VPIM messages from the sending VPIM
Location to extensions.
 Routing Rules: When a routing rule is matched, the routing rule’s
search space is set to be the search space of the call.
 Templates: When an object is created using a template the object
is created with the templates search space.

Deleting a partition
To delete a partition it must be empty. If you try to delete a partition
that is in use you will get an error. You can look at each object
using the “Limit the Search to” “partition” option. Here is a list of
objects: subscriber (Check the Display and Alternate Extensions
radio button), contacts, VPIM locations, System Call Handlers,
Interview Handlers, and Directory Handlers.

Deleting a search space:
When an administrator deletes a search space the administrator is
asked to select a replacement search space. All objects assigned
to use the original search space, will be assigned to use the
replacement search space, and the original search space will be
deleted.
There will be a log file called SearchspaceRemovalLog.txt describing what
happened during this operation.

Advanced Searches using Search Spaces
When Unity Connection is doing a search using the VPIM location’s
“dtmf access id” plus “VPIM Remote Mailbox Number” or Vui’s
“Contact’s name or VPIM Remote Mailbox Number ” at “VPIM
location’s name” syntax the VPIM’s locations partition membership
is checked. Then all contact’s associated with the VPIM location
that match the “VPIM Remote Mailbox Number” or “Contacts
name” are returned regardless of their partition membership.
For example, if you have a VPIM location with the “Seattle” name
and a dtmf access id of 8256, then these searches will all work if
the VPIM location is in a partition in the current search space:
82563071, “Aaron Belcher” at “Seattle” and “3071” at “Seattle”

Using Search Spaces to Restrict access to
contacts.
If the customer want’s to restrict the contacts that a subscriber can
access, they should:
 1. Not add the VPIM locations partition to the subscriber’s search
space. (This affectively, disabled the dtmfaccessid and “at” VUI
syntax.
 2. Assign the contacts that the subscriber can access to a partition
in the subscribers search space.
 3. Assign the contacts that the subscriber can’t access to a
partition outside of the subscribers search space.

Deployment Recommendation’s for multi-site
deployments.
 Create one partition for globally unique numbers on each server.
 Create one partition for each site homed on each server or rename
the default partition.
 Create one search space per site or rename the default search
space.
 Add the site’s partition followed by a globally unique partition’s to
it’s search space.
 Assign all the subscribers to corresponding partition/search space.

Configuring dial plan with CUCM:
1. Unique outdial numbers:
Create a hunt pilot per site on CUCM
Create a routing rule to match the hunt pilot and assign the search
space of the call to associated site.
For transfers and outdials always use the unique number outdial
number…
2. Per site/voicemail ports.
Create a set of voicemail ports per site on CUCM
Create a switch on Unity Connection per set of voicemail ports
Create a routing rule to match the switch and assign the search space
of call to the site.

Common Issue 1: Can’t find remote Users
 Issue: A networking node was added but users can’t find remote users.
 Solution: Add the remote partitions to the local search space once
replication has completed.
 Diagnostics: Conversation Manager

 Issue: A user can’t log in over the TUI.
 Solution: Make sure the routing rule is pointing to call search space that
include the subscriber
 Diagnostics: Conversation Manager

Common Issue 3: NDR’s from VPIM
 Issue: NDR’s from VPIM
 Solution: Make sure that the recipient’s extension is in a partition
