On this panel, you can check how the translation rules (that you specified on the Translation rules panel) work.
For example, you set the ANI translation rule s/$/@ani/ that should instruct the system to add @ani suffix to the ANI number of the incoming call and search for an ANI@ani account (e.g., 16041112222@ani) for authentication and authorization. To check this rule, enter a phone number, e.g., “16041112222” in the Check ANI translation rule field and click Check. As a result, you can see the number after applying the translation rule in the Number after translation field.
In the same way, you can check the specified PIN translation rule.
