A identity defines the basic settings that are used to connect to a remote party. The web frontend and the phone ui allow configuration of the most common settings.
The provisioning provides means to set the remaining settings.
Minimal example configuration (based on version 1.2):
<identity> <username>61</username> <!-- registration information used to connect to the server/pbx. On Auerswald pbxs the phones number is used as the username --> <password>aSecretPassword</password> <registrar>192.168.1.100</registrar> <!-- server or pbx. Can be a hostname or an ip address --> </identity>
A full configuration example can be found here.
