XConnect and Acme Packet, Inc. today announced the successful testing of new methods that assist in the prevention of Spam over Internet Telephony (News - Alert) (SPIT), also known as voice spam.

 

Similar to that of email spam, SPIT is a threat to the growing VoIP communications sector. However, with the increasing popularity of VoIP, the disruptive and intrusive nature of unwanted calls, coupled with the difficulty in detecting SPIT make it worse to ignore the problem. Hence, preventive actions are taken by industry bodies such as the Internet Engineering Task Force (IETF) to develop new approaches to deal with SPIT.

 

In such a development, peering federations use upstream SIP elements to tag or mark call attempts with a spam score indicating the likelihood of SPIT. Session border controllers (SBCs) are then configured at the borders between originating and terminating networks to interpret these scores and act accordingly.

 

Such approach is ideal for managed federations and many of XConnect's (News - Alert) customers have demanded significant SPIT detection and protection measures as prerequisites to enabling secure multi-lateral interconnections. XConnect and Acme Packet (News - Alert) are working together to implement this new methodology for the first time.

 

"Until now, the few industry attempts to implement SPIT prevention have been ineffective, because approaches that mimic email spam solutions do not account for the realities and architectures of voice," said Eli Katz (News - Alert), CEO of XConnect. "XConnect's approach is the first to create an industry-standards-based infrastructure to allow calls and multimedia IP sessions to be identified and tagged with advanced SPIT threat information. This enables communication service providers to deal with this potential threat in an intelligent manner, on a call-by-call basis."

 

"As more and more VoIP networks become interconnected, SPIT has the potential to create a plague that's even worse than email spam," stated Seamus Hourihan (News - Alert), vice president of marketing and product management at Acme Packet. "Acme Packet, leveraging its Net-SAFE (Session-Aware Filtering and Enforcement) security framework, is committed to working in tandem with VoIP peering federation providers, such as XConnect, who are actively engaged in preventing SPIT as well as other undesirable network activity."

 

"SPIT may not be a household word yet, but service providers understand the potential for detracting from the VoIP experience," said Jon Arnold of J. Arnold & Associates. "This spam score will provide another valuable metric to determine the quality of VoIP traffic that is being peered between service providers."
