In most cases you will lose this customer. They don't see this as their responsibility (i.e. the credit card fraud defense) but the reality is their equipment was compromised due to their negligence. If the customer is reasonable offer them your cost on the damages so its just a passthrough. Otherwise you can take them to court or just send them to collections. BTW while many will advocate fraud detection and mitigation systems here, its been my experience (we wrote our own fraud system that out-performs our upstream carriers by hours) that if you detect fraud on a customer like this, and shut it down in minutes, and mitigate what could have been thousands of dollars in damage due to their mis-configured systems, reducing it to just tens or hundreds they will often still fight that amount and deny responsibility. The fraud system protects you, and by extension the customer, but the customers don't see it that way. -Ryan On 02/19/2014 02:09 PM, John Curry wrote:
I am new to your site. I was looking in the Archives and saw in November 2013 there were some of you who experienced fraud. We had a an Avaya IP Office customers system who got hit pretty bad. The customer is treating the fraudulent calls like credit card fraud and not taking any responsibility. Does anyone have any advice on how to persuade the customer take this issue seriously? His bill was racked up pretty good. Strangely and coincidentally Avaya came out with a security bulletin the end of December 2013 on this same issue. I tried to contact Avaya with no response. It seems as though someone has built a sniffer for the Avaya IP Offices and gleaning their registrations.
