<p class="MsoNormal"><span style="font-size:11.0pt">By default we block all international calls on users (011 dialed) and will enable using auth codes or outright if the customer insists and bears all potential costs. That has significantly reduced / eliminated
international toll fraud on our switch. Now, we see fraud going to NANP (1+ dialed) high cost ratecenters/NPANXXs.

<p class="MsoNormal"><span style="font-size:11.0pt">Does anyone know how to mark the high cost NPA-NXXs in the Broadworks Network Server so the calls are marked as high cost / expensive? Then I can treat them as international and block or require an auth code.<o:p></o:p></span></p>
