Creating Provisioning Scripts Using Provisioning Parameters 2 General Purpose Parameters The general purpose parameters GPP_* are used as free string registers when configuring the IP Telephony device to interact with a particular provisioning server solution. The GPP_* parameters are empty by default. They can be configured to contain diverse values, including the following: • Encryption keys • URLs • Multistage provisioning status information • Post request templates • Parameter name alias maps • Partial string values, eventually combined into complete parameter values. The GPP_* parameters are available for macro expansion within other provisioning parameters. For this purpose, single-letter upper-case macro names (A through P) are sufficient to identify the contents of GPP_A through GPP_P. Also, the two-letter upper-case macro names SA through SD identify GPP_SA through GPP_SD as a special case when used as arguments of the key URL option. For example, if GPP_A contains the string ABC, and GPP_B contains 123, the expression $A$B macro expands into ABC123. Enables All profile resync and firmware upgrade operations are controlled by the Provision_Enable and Upgrade_Enable parameters. These parameters control resyncs and upgrades independently of each other. These parameters also control resync and upgrade URL commands issued through the administration web server. Both of these parameters are set to yes by default. In addition, the Resync_From_SIP parameter controls requests for resync operations via a SIP NOTIFY event sent from the service provider proxy server to the IP Telephony device. If enabled, the proxy can request a resync by sending a SIP NOTIFY message containing the Event: resync header to the device. The device challenges the request with a 401 response (authorization refused for used credentials), and expects an authenticated subsequent request before honoring the resync request from the proxy. The Event: reboot_now and Event: restart_now headers perform cold and warm restarts, respectively, are also challenged. Cisco Small Business IP Telephony Devices Provisioning Guide 48

General Purpose Parameters
The general purpose parameters GPP_* are used as free string registers when
configuring the IP Telephony device to interact with a particular provisioning
server solution. The GPP_* parameters are empty by default. They can be
configured to contain diverse values, including the following:
•
Encryption keys
•
URLs
•
Multistage provisioning status information
•
Post request templates
•
Parameter name alias maps
•
Partial string values, eventually combined into complete parameter values.
The GPP_* parameters are available for macro expansion within other provisioning
parameters. For this purpose, single-letter upper-case macro names (A through P)
are sufficient to identify the contents of GPP_A through GPP_P. Also, the two-letter
upper-case macro names SA through SD identify GPP_SA through GPP_SD as a
special case when used as arguments of the
key
URL option.
For example,
if GPP_A contains the string ABC, and GPP_B contains 123, the
expression $A$B macro expands into ABC123.
