Eco Cast is an audition management system that allows Casting Directors to manage their recorded auditions, and even invite actors to self tape auditions that they upload themselves. 

As an actor, you will get an Eco Cast invite that will allow you to record audition material based on Casting Director instructions and transmit the requested files to them.
