Static Provision Configuration
To use the static provision method, you need to obtain the provisioning server address first when configuring a pro-
visioning server.
The provisioning server address can be IP address, domain name or URL. If a user name and password are spe-
cified as part of the provisioning server address, for example, http://user:pwd@server/dir, they will be used only if
the server supports them.
Note: A URL should contain forward slashes instead of backslashes and should not contain spaces. Escape characters are
not supported.
If a user name and password are not specified as part of the provisioning server address, the User Name and Pass-
word of the provisioning server configured on the phone will be used.
The following table lists the parameters you can use to configure static provision.
Parameter
static.auto_provision.server.url <y0000000000xx>.cfg
