hello everyone. i am concerned about security to the PBX and i would like to discuss different fraud detection methods. Apart from making everything to secure the PBX (latest patches, iptables, firewalls, no outside users, strongs passwds,...) i would like to find out if there are any fraud detection techniques. As for my setup i do have a PBX running asterisk 11.4 and it has 3 sip trunks (over

I worked on some ad data before and I found NYT article very biaised and not far from a fraud... Anyone knows if they got money from a - company - to play 'R'? Check out the title: R U Ready for R? Seems to me this title was stolen from XLSolutions www.xlsolutions-corp.com and they never mentioned XLSolutions in the article! They mentioned commercial R....never mentioned

I charge my customers through PayPal, but recently faced a fraud which previously had only heard about. Somebody registered a few accounts, paid online with paypal (as my service is only prepaid) and started making expensive long distance calls. In fact the IP registering the accounts was from Florida, and IPs making calls were from Africa. After about 20 minutes the first payment was reversed.

So I've been working with Random Forests ( R library is randomForest) and I curious if Random Forests could be applied to classifying on a real time basis. For instance lets say I've scored fraud from a group of transactions. If I want to score any new incoming transactions for fraud could Random Forests be used in that context. Linear Regression is nice in that it is very easy to

Hi, Some days ago I spent about US$700,00 in a Tormenta III board in www.govarion.com. I used credit card. I didn't receive any answer for my emails and there is no telephone number to contact them.. Now, I'd like to cancel this order, because I couldn?t wait so long, and my credit card was billed. Is www.govarion.com a fraud ???? Does anybody know something about them ?? Thanks.

I'm looking for a prepaid calling card platform that: * easily scales to multiple servers with a common database for: redundancy, capacity, and performance Looking to start with capacity to handle 100 simultaneous calls and be able to easily scale to 1000+ simultaneous calls. * in addition to the normal anti-fraud measures, supports an API for easily adding new anti-fraud tests along the

Did anyone else who purchased the Rails betabook get a telephone call from someone at "Humboldt Merchants" (sp?) asking to verify their purchase, ostensibly to ensure there was no fraud (on the part of the merchant, not the person buying the book)? They knew my name, phone number, the title of the book I bought and the type of credit card I used. They didn''t give or ask for the

I have successfully, by now, installed a samba server. I can log on from win98 and 95 computers. I can see the shares and use some of it. There are a couple of shares [Home] [Document] I can browse the share and a user, "Mats", can read and write copy and so on in /home/Mats, so obviously the server recognizes the user as the Linux user with the same name. (in smbusers there is a

Did you have a look at the phone it self already? Is call forwarding activated or something and can you call the phone/extension from externally? I have seen this in the past where an employee enabled call forwarding on the phone and once at home he or family called the phone which forwarded the call to abroad. Good luck. Michel.

Hi, Embarrassed as I am to write this, I am hoping for some advice. One of our very first PBX installs, now six years old, was "taken advantage of" over the past few weeks. A victim of sipvicious, I assume, that managed to guess one of the SIP passwords. 4000 calls to various middle eastern destinations have been placed, which ended up being sent over our customer's PSTN

This seems like a piece members of this list would find interesting... === There is growing concern over the interaction of VoIP systems with the legacy PSTN, and the transmission of caller identity data--most notably, Caller ID on the PSTN. It is not always possible, or obvious how, to handle Caller ID data when moving to or from VoIP and the PSTN networks. There are even business models

You don't mention if the phone is remote, or local. Although you do mention it had a default user/pass. If the UI of the phone was/is accessible from the I'net, the GUI does have the ability to place a call from it, that is one way the calls could have been placed.
