Feature Provisioning

Features with standard profile-based data can be configured (provisioned) using the Sentinel VoLTE REST API or web UI. These are provided by the Sentinel VoLTE Element Manager REM plugin. This includes any custom configuration or address lists the features may use.

See Provisioning in the Sentinel VoLTE Administration Guide.

Java annotations on the feature source are used to define exactly what can be configured for each feature. When modules are built, the provisioning annotations are processed by the sentinel-feature-annotation-processor.

The provisioning metadata is registered with Sentinel VoLTE when the service in which the feature is bound gets activated. This metadata is then queried dynamically at runtime by the provisioning system to produce the REST API and web interface.

So, for a feature to have a REST API and web interface made available it must:

In previous versions of Sentinel VoLTE, each feature with provisionable configuration had to publish a provisioning.xml file. That file was then used at built time of the Sentinel VoLTE Element Manager to generate the REST API and web UI for that feature. This approach required a rebuild and reinstall of the Sentinel VoLTE Element Manager REM plugin every time the provisioning metadata was changed. The provisioning.xml approach is still supported for backward compatibility, but the new annotation-based approach is to be preferred.

A tool has been provided to automatically convert any existing features using the old provisioning.xml files to use the new annotation-based approach. To install the tool, run the Ant build target install-provisioning-annotations-converter under the sentinel-volte-sdk/tools directory and follow the printed instructions.
