NEC Warns on VoIP Spam

NEC, the networking vendor, expects telephony spam levels to soar to between 40% and 70% of all calls.

While sending junk messages is too expensive over traditional networks because of call charges, NEC believes that the volume of telephone spam, created via Botnet platforms, could explode as more telephony is delivered over IP networks.

NEC has developed a software add-on to its PBXs, which claims to stop up to 99% of unsolicited VoIP calls, which are known as Spam over Internet Telephony (Spit).

The company’s Seal software uses a variety of criteria to detect spam calls, such as a high volume of calls originating from on IP address. The software can reject these calls or send them to voicemail. It is also able to blacklist callers by caller ID or IP address.

NEC will demonstrate the software at the 3GSM World Congress which will be held in Barcelona in February.
