In case you are using auto provisioning via the 3 step method:

  1. provisioning .xml
  2. update.xml
  3. MAC.xml

The file that contains the settings "MAC.xml" has the following file structure.

<?xml version="1.0" encoding="UTF-8"?>

<settings version="1.0" productID="mx3b" macAddress= "7c:2f:80:9c:f3:75">

<!-- SIP -->

<param name="SIP.DefaultAccount" value="0" />

</settings>

You can see in the Example that the field macAddress= "7c:2f:80:9c:f3:75" is used.

When the field is used, then the MAC address of the device should be the same like configured, if not, then the settings are not taken.

The usage of the "macAddress" is optional, when you do not want to use it see example below.

<?xml version="1.0" encoding="UTF-8"?>

<settings version="1.0" productID="mx3b">

<!-- SIP -->

<param name="SIP.DefaultAccount" value="0" />

</settings>
