Based on your update type, you might need to set the version number of your built-on application. If you are performing a major update, for example, you are updating from 7.x to 8.x, you need to set the version number of your built-on application so that you can use the latest features in Pega Call™.

1. In the header of Dev Studio, click ApplicationDefinition.
2. In the Built on applications section, change the value in the Version field to the number of the updated version.
   For example: 8
3. Click Save.
