Texas Instruments Inc. today announced a new suite of industry-compliant security features for Voice over Internet Protocol (VoIP)-enabled customer premises equipment (CPE) applications.

TI’s security framework is designed to make IP phones and VoIP gateways less vulnerable to denial-of-service attacks, while ensuring higher Quality of Service (QoS) levels for packet-based voice traffic.

Secure voice communications has gained the attention of service providers, equipment manufacturers and end users alike, and has evolved into a key requirement for VoIP solutions, the company said.

“Network devices such as IP phones and VoIP gateways are particularly vulnerable to denial-of-service attacks because voice connections require consistent and reliable access to enterprise networks to ensure adequate QoS,” it said.

While attackers commonly use malformed frames or packet floods to execute these attacks, TI said its approach pre-screens incoming packets thereby reducing or eliminating their effectiveness.
