The first phase of the process is to normalize the incoming numbers and set the Exchange Subscriber's Access (EUM SA) phone number.

1. Create an Action for releasing calls using the Action Configuration menu .
   This is used (for Action: Release Call, for Q.850 Cause Code: 16: Normal Call Clearing). HTis is for calls that have completed processing, but are still not routed.
