Cisco TMS Provisioning
Cisco TMS provisioning is the mechanism through which the Expressway and Cisco TMS share FindMe and device
provisioning data. The shared data includes:
provisioning data. The shared data includes:
■
from endpoint devices

The FindMe and Device Provisioning option keys must be installed on the Expressway for it to provide FindMe and
provisioning services.
provisioning services.
As from version X8.8, the Expressway supports only the Cisco TelePresence Management Suite Provisioning
Extension (Cisco TMSPE) services to provide the Expressway with provisioning and FindMe data. In this mode all
provisioning and FindMe data is managed and maintained exclusively within Cisco TMS.

Size limitations for clusters and provisioning
An Expressway cluster of any size supports up to:
■
10,000 FindMe accounts
■
10,000 users for provisioning
■
200,000 phonebook entries
Note that:
■
systems can support up to 2,500 device registrations per peer, subject to a maximum of 10,000
registrations per cluster. Typically this means one device per FindMe account.
■
systems can support up to 5,000 device registrations per peer (with a maximum of 20,000 registrations
per cluster). However, you are still limited to 10,000 FindMe accounts/users and 10,000 provisioned devices
per cluster.
per cluster.
If you need to provision more than 10,000 devices, your network will require additional Expressway clusters with an
appropriately designed and configured dial plan.

Cisco TMSPE services
When TMS provisioning is enabled, the Expressway uses the following Cisco TMSPE services (which are hosted on
Cisco TMS) to provide the Expressway (or Expressway cluster) with provisioning and FindMe data:

Description
User
Preference
The data provided by the User Preference service enables the Expressway to configure a device with
settings that pertain to a specific user (a user is essentially a SIP URI). Devices such as Jabber Video
are configured entirely using this service. This service also provides connection details to a
TURN server (typically the Expressway-E).

FindMe
The FindMe service provides the details of users' FindMe accounts, in particular the locations and
devices associated with each FindMe ID. This allows the Expressway to apply its User Policy, and to
be able to change a caller's source alias to its corresponding FindMe ID.

Phone
books
The Phone books service provides the data that allows users to search for contacts within phone
books. Access to phone books is controlled on a per user basis according to any access control lists
that have been defined (within Cisco TMS).
