Some Asterisk configuration files also create objects. The syntax for objects is slightly different than for settings. To create an object, you specify the type of object, an arrow formed by the equals sign and a greater-than sign (=>), and the settings for that object.
[section-name] some_object => settings
[section-name] label1=value1 label2=value2 object1 => name1 label1=value0 label3=value3 object2 => name2
In this example, object1 inherits both label1 and label2. It is important to note that object2 also inherits label2, along with label1 (with the new overridden value value0) and label3.
In short, objects inherit all the settings defined above them in the current section, and later settings override earlier settings.
