Asterisk for outgoing call with Adhearsion

I was trying out my luck working asterisk with Adhearsion. Could get the initial setup of the installation and created a ahn project.

I would like to make an outgoing call using the Adhearsion and as well work the text to speech functionality work. Any thoughts or any documentations available for this.

I could not as well find any forums for the adhearsion. could you pass on the link for the same.
