This is a prerequisite for using the Device Connector tool, which allows you to onboard and register several devices

simultaneously to the Webex Control Hub1. The Device Connector tool creates a workspace, an activation code, and

activates all of your devices in one go1. This way you don’t need to be physically present in the same room to activate

the devices.

The other options are not required before onboarding devices by using the Control Hub:

Configuring the Control Hub organization ID on the devices is not necessary, as the Device Connector tool will send the

device information to your Webex organization and generate activation codes for them1.

Acquiring a license for each device is not necessary, as you can assign licenses to users and devices after they are

registered to the Webex Control Hub2.

Allowing HTTP traffic from each device to Control Hub is not necessary, as HTTPS connectivity is required for the Device

Connector tool to communicate with the devices1.

SRST, or Survivable Remote Site Telephony, is a feature that allows Cisco IP phones to continue to function even when the

connection to the Cisco UCM publisher is lost. When SRST is configured, the phones will automatically reregister to the

publisher when the connection is restored.

Route groups are used to route calls to different destinations based on the caller's phone number or other criteria. Cisco

UCM is the call management system that controls the IP phones. Device pools are used to group phones together for

administrative purposes.
