Starter Pack provisioning

The VCS's Starter Pack Provisioning Server provides basic device provisioning, including phone book
support, for a range of endpoint device types without the need for Cisco TMS.

The

Starter Pack

option key must be installed to use basic device provisioning. It cannot be used in

combination with device provisioning managed through TMS. Note that the

Starter Pack

option key is

designed for single box deployments and is only available as a pre-configured factory setting.

Starter Pack

The Starter Pack is suitable for small enterprises. It provides basic VCS functionality and includes

Expressway

and

FindMe

functionality automatically.

The following license restrictions apply by default:

n

50 registrations

n

5 traversal calls (extra traversal call license option keys can be added if required)

n

900 TURN relays

Note that:

n

non-traversal calls are supported (a traversal license is used when one occurs)

n

the Starter Pack has a maximum limit of 25 calls

When the

Starter Pack

option key is installed the Presence Server and FindMe are automatically enabled.

Configuring Starter Pack provisioning

The

Provisioning

page (

Applications > Provisioning

) is used to configure the VCS's

Provisioning Server

when the VCS is running in Starter Pack mode.

The Starter Pack Provisioning Server provides basic device provisioning and is automatically enabled when
the

Starter Pack

option key is installed. It can be monitored on the

Starter Pack status

page.

Bandwidth limits

The

Bandwidth limits

section lists each supported device type and lets you choose whether or not to enable

the provisioning of bandwidth limits for that device. If you enable the bandwidth limits option for a device type
you can then configure the maximum incoming and outgoing bandwidth (in kbps) values to set on the
provisioned devices.

ClearPath

The

ClearPath

section lists each supported device type and lets you choose whether or not to enable the

provisioning of ClearPath for that device.

Provisioning users

To provision individual users, you must set up

FindMe accounts

. When you configure a FindMe account, you

can choose the devices to provision for that user. The FindMe account is also used to configure the user's
FindMe settings.

See

VCS Starter Pack Express Deployment Guide

for full details on setting up Starter Pack provisioning.
