Whether you choose to develop your application using CPI or SimpleFax utilities, we strongly recommend that you register as a FaxPress developer. As a registered developer you will periodically receive updates to the SDK and utilities. This will also give us the opportunity to get your feedback about the API, utilities and enhancements that you would like in the future releases of the product and the SDK.
