Zero Touch Deployment

Introduction

Zero Touch Deployment describes a method of deploying a Desk Phone CP SIP device, without user interaction, via the Unify redirect server. For this to work, a service provider needs access to the redirect server API, in order to prepare the deployment of the device. On initial startup or after a factory reset, the device will contact the redirect server and will receive information about the service providers deployment system.

Provisioning details

The Desk Phone CP SIP device will only contact the redirect server for zero touch deployment under certain circumstances. It must be running with factory default settings (out of the box or after a factory reset), it must not be configured with a SIP, DLS, DMS or ACS server address via DHCP and it must be able to resolve and access cloud-setup.com on port 18443

The phone will connect to the address of cloud-setup.com and check for a zero touch deployment profile being available. If it is not available (e.g. because the service provider has added the profile after the initial start of the device), the device needs to be restarted in order to restart the zero touch deployment process.

In the process of connecting to cloud-setup.com, the phone will validate the connection to the server via a hard coded root certificate that comes with every phone software version.

API

The redirect server API is available at https://cloud-setup.com/api/devices and supports the following methods

• POST
• PUT
• DELETE

Authentication

Access to the API is authenticated via certificate based mutual authentication. Every service provider will get an individual certificate.

POST

The POST method is used to retrieve information about devices prepared for zero touch deployment. The data sent in the POST request must contain the mac address of the device.

 {"mac":"01:23:45:67:89:ab"}

the mac address can be provided in the following format

Key	Value
mac required	01:23:45:67:89:AB 01-23-45-67-89-AB 01:23:45:67:89:ab 01-23-45-67-89-ab

The data received on a successful request with HTTP response code 200

 {"mac":"01:23:45:67:89:ab","data":"'<Item name="bw-dms-addr">https://192.168.0.100/home</Item>\r\n<Item name="language-iso">de</Item>'"}

Key	Value
mac	The MAC address sent in the request or ERROR if no MAC given.
certificate optional	If a certificate is prepared for the provided MAC address, will contain the lifetime.
data optional	If the response code is 200, value will contain the data prepared for the given MAC address.
reason optional	If the response code is not 200, will contain the reason for the response.

PUT

The PUT method is used to prepare information about devices for zero touch deployment. The data sent in the PUT request must contain the mac address and either the deployment data of the device or the certificate request.

 {"mac":"01:23:45:67:89:ab","certificate":"true","data":[Data-Object]}

the mac address can be provided in the following format

Key	Value
mac required	01:23:45:67:89:AB 01-23-45-67-89-AB 01:23:45:67:89:ab 01-23-45-67-89-ab
certificate optional	"true" or "false"
data optional	The data provided as another Array of supported item objects

The Data-Object

 [{"name":"acs-server-address","value":"https://acs.cloud-provider.com","index":"0"},...]

Key	Value
name required	The name of the item
value required	The value of the item with a maximum of 255 characters
index optional	Contains the index value of the item

The data received on a successful request with HTTP response code 200

 {"mac":"01:23:45:67:89:ab","certificate":"{Certificate-Object}","data":"[Data-Object]"}

Key	Value
mac	The MAC address sent in the request or ERROR if no MAC given.
certificate optional	If a device certificate certificate was requested, will contain the result of the request.
data optional	Will contain the result of the data prepared for the given MAC address.
reason optional	If the HTTP response code is not 200, will contain the reason for the response.

Result for Certificate-Object

 {"code":201,"serial":"..."}

Key	Value
code	The response code of the request. 201 on successful creation.
serial optional	If the response code is 201, will contain the serial number of the certificate created.
lifetime optional	If the response code is 200 because a certificate already exists, will contain the lifetime of the current certificate.
reason optional	If the response code is not 201, will contain the reason for the response

Result for Data-Oject

 [{"name":"acs-server-address","code":200},...]

Key	Value
name	The name of the item.
code	The response code of the request. 200 on success.
reason optional	If the response code is not 200, will contain the reason for the response

DELETE

The DELETE method is used to delete information about devices prepared for zero touch deployment. The data sent in the DELETE request must contain the mac address of the device.

 {"mac":"01:23:45:67:89:ab"}

the mac address can be provided in the following format

Key	Value
mac required	01:23:45:67:89:AB 01-23-45-67-89-AB 01:23:45:67:89:ab 01-23-45-67-89-ab

The data received on a successful request with an HTTP response code of 200

 {"mac":"01:23:45:67:89:ab"}

Key	Value
mac	The MAC address sent in the request or ERROR if no MAC given
reason optional	If the response code is not 200, will contain the reason for the response
