Joe thanks for your comment.

You are absolutely correct that a Voice FW would be a better solution, however most “mom and pop shops” or even slight larger offices may not have that option in their budget. It’s sad but true that allot of these are poorly misconfigued and throw up onto net with the notion if it works, leave it.

Security does not become an issue until they are exposed, granted a simple access list will not protect you entirety but it will keep an honest person honest. Think of putting a lock on a door, if someone really wants to get in they will.

In summary any major corporation or government agency worth their salt is going have an elaborate security policy in place. Whether is be voice, data or physical.

The only way to prevent dial through fraud is to place a SecureLogix Voice FW on the PSTN connection. The issue is that PBX’s, Gateways, VoiceMail systems, IVR,s modems, faxes, Dialers, Call Center Suites of all vintages, makes and models, IP or TDM as well as the carrier do not tell the enterprise what the wireline attributes of the individual calls are. Sure…they have databases but those cannot enforce policy and at best are rarely updated properly. Trust nothing is what we go by. You need attribute identification to build policies that give real time visibility and control into the “PSTN Edge”. We identify attributes such as Call Type(is that a modem, fax, human voice, STU, wideband video, Modem energy etc. As well as source, destination, time of day, direction, action, etc. Very similar to a packet only FW. Once attributes are collected they can then fill out the various security and enforcement policies(FW, IPS/Fraud prevention, Usage manager, performance Manager, Policy based call recording) Dial through fraud is a multi-billon $ global issue. In some cases is actually tied to funding terrorist activities. We have 15 patents granted in this space and sit on more than 4 million lines. Many marquis enterprises and Federal Agencies depend on us. We are a Cisco Development Parter, A member of the Cisco SmartGrid Ecoystem as well as a feature in their channel programs.
