NEC technology fights IP phone spam

NEC plans to showcase at the 3GSM World Congress new technology aimed at blocking VOIP spam.

NEC has developed technology that can help prevent spam phone calls to VOIP (voice over Internet Protocol) users.

The company plans to demonstrate the technology next month at the 3GSM World Congress in Barcelona but still has more work to do before it can sell a commercial product.

The technology discovers whether a caller is a human or a machine by testing the machine's capability to perform human-like conversation. Once the technology determines that a machine has made the call, it blocks the connection, preventing the user's phone from ringing.

NEC has developed the technology so that new modules can quickly be added to the system to respond to new and different kinds of VOIP spam.

In addition, the product will be customizable to work with different types of hardware, such as SIP (Session Initiation Protocol) servers, home network equipment and session border controls.

NEC tested the technology during a simulated VOIP spam attack, using well-known botnets to create the attack. The technology detected nearly all of the VOIP spam in the test, NEC Said. A botnet is a collection of computers that have been infected by malicious code and can be remotely commanded to execute malicious activities.

Existing botnets can easily be modified to produce spam telephone calls, NEC said. The company warned that a high level of VOIP spam could discourage the growth of VOIP.

NEC did not say when a commercial product might become available.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
