When the phone is performing the auto provisioning process via a relative URL, the phone will request the 
following three default configuration files in turn.  
•  config.xml 
•  config.$model.xml 
•  config.$mac.xml 
If you want to customize the configuration file, you can create some new files by making a copy and 
renaming the configuration template file, then save the configuration file and place it on the provisioning 
server. The IP phone will request the customized file.  
For example, set the DeviceProvisionFileFirst to 1.xml, set the DeviceProvisionFileSecond to 2.xml, and 
set the DeviceProvisionFileThird to 3.xml, the phone will request the following three configuration files in 
turn. 
•  1.xml 
•  2.xml 
•  3.xml 
Note: The ALE Myriad Series phones only support the xml format config file.  
3.6.3 Timeout Mechanisms 
In the process of auto provisioning, there are two kinds of timeout mechanisms for some abnormal 
scenarios. It provides a clearer definition of some behaviors of the phone when there are network issues and 
can also improve the efficiency of the auto provisioning process. 
The following table lists the parameters you can use to configure the settings of timeout in auto provisioning 
process.
