Zak, this occurs because their PBX (to which the trunks are connected) gets hacked?<div><br></div><div>The first step is to block International unless the customer requires it. You can set maximum call duration, but that is only an inconvenience to the hackers to make them dial again. You can try to get the customers to use account codes for International. You can set time schedules (this might be tricky and may need to do in the NS). And you need a fraud detection system to alert you when it happens so that you can minimize the damage. Last but not least, you can try and make the customer pay for the usage (that never works).<br>

<p class="MsoNormal"> </p><p class="MsoNormal">We have a series of smaller SIP trunk customers using Broadsoft trunk groups. By design the trunk groups have a concurrent call limitation based off the customer’s order. These smaller SIP trunks groups when compromised are able to run up HUGE fraud bills even tho they only have 5 or 6 SIP trunks. Needing to know if anyone else is seeing this that has Broadsoft and what was done to protect yourselves?</p>
