Update on this incase anyone is interested. I got this working on my Broadworks (R20sp1) http://xchange.broadsoft.com/php/xchange/node/449863 I added all of the Caribbean NPAs to the NDC table setting the Alternate Call Indicator to their ISO-3166 Alpha 2 code (2 letter country code). Now I can easily enable/disable the islands in the NANP through a Communications Barring Profile. My country 1 NDC looks like: Country Code From To Name Min STNC Length Max STNC Length NDC Length Zone Rate Center LCA Id Call Ind ============================================================================================================================================== 1 201 241 North America 7 7 3 1 242 242 The Bahamas 7 7 3 aci=BS 1 243 245 North America 7 7 3 1 246 246 Barbados 7 7 3 aci=BB 1 247 263 North America 7 7 3 1 264 264 Anguilla 7 7 3 aci=AI 1 265 267 North America 7 7 3 1 268 268 Antigua and Barbuda 7 7 3 aci=AG 1 269 283 North America 7 7 3 1 284 284 The British Virgin Island 7 7 3 aci=VG 1 285 33 North America 7 7 3 1 340 340 The U.S. Virgin Island 7 7 3 aci=VI 1 341 344 North America 7 7 3 1 345 345 The Cayman Islands 7 7 3 aci=KY 1 346 440 North America 7 7 3 1 441 441 Bermuda 7 7 3 aci=BM 1 442 472 North America 7 7 3 1 473 473 Grenada 7 7 3 aci=GD 1 474 648 North America 7 7 3 1 649 649 The Turks and Caicos Island 7 7 3 aci=TC 1 65 663 North America 7 7 3 1 664 664 Montserrat 7 7 3 aci=MS 1 665 720 North America 7 7 3 1 722 757 North America 7 7 3 1 758 758 Saint Lucia 7 7 3 aci=LC 1 759 766 North America 7 7 3 1 767 767 Dominica 7 7 3 aci=DM 1 768 783 North America 7 7 3 1 784 784 Saint Vincent and the Grenadines 7 7 3 aci=VC 1 785 808 North America 7 7 3 1 809 809 The Dominican Republic 7 7 3 aci=DO 1 81 828 North America 7 7 3 1 829 829 The Dominican Republic 7 7 3 aci=DO 1 83 848 North America 7 7 3 1 849 849 The Dominican Republic 7 7 3 aci=DO 1 85 867 North America 7 7 3 1 868 868 Trinidad and Tobago 7 7 3 aci=TT 1 869 869 Saint Kitts and Nevis 7 7 3 aci=KN 1 870 875 North America 7 7 3 1 876 876 Jamaica 7 7 3 aci=JM 1 877 938 North America 7 7 3 1 94 990 North America 7 7 3 -Matt -- Matthew Crocker Crocker Communications, Inc.

We made that list from various online sources regarding call fraud. Some of the Caribbean, Nigeria and other African regions, etc. The only complaint we had over the years was for one Caribbean area code that is high fraud, but low cost, so we enabled it. We then have our carrier capped at something like 25 cents/min and a daily dollar cap. I think we could share our list, however it was built many years ago and you probably want to re-research it yourself.

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. Is there a list of the high cost NPA-NXXs or should I just go through my upstream carriers rate deck and sort by $$/MOU? 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. -Matt -- Matthew Crocker Crocker Communications, Inc.
