« Lots of Press on Telephony Denial of Service (TDoS) | Main | Massive Scan of the Internet for SIP Servers »

May 20, 2013



Hi, Mark:

I have seen this kind of thing firsthand myself, though not to the tune of $600000.

However, it is important to let readers know that this kind of thing happens all the time with analog and digital PBX systems as well as VoIP systems. In fact, in my experience, the typical VoIP provider has much better fraud detection for expensive routes than the telephone companies like AT&T and Verizon.

Please don't let your headline and post here be used to scare off potential consumer, SMB or enterprise VoIP customers. My point is that it actually may be easier to hack legacy systems for profit than a VoIP system.

Thanks for the post - I agree. This issue has nothing to do with VoIP, as you say it can occur on any type of PBX/IP PBX system. Pretty much all of the issues I talk about can occur for TDM/legacy or VoIP/UC system.
