Hi Michele,
<div><br>
</div>
<div>As Bill said, only TDM is supported at this time. Although CUBE recently released support for CPA in DSPs that is not involved in call termination, there are still some things we have to work out. </div>
<div><br>
</div>
<div>You can track CSCui62525. When this gets integrated I hope we’ll support CUBE for IVR-based Outbound Dialer with UCCX. </div>
<div><br>
</div>
<div>You can also see this article which talks a little bit more about it. </div>
