Voice Over IP Traffic

Increasingly, corporate Chief Information Officers (CIOs), IT administrators, and end-users are focusing on the security aspects of IP telephony infrastructure. Protecting Voice over IP (VoIP) traffic, including both signaling and media, from various attacks such as eavesdropping, toll fraud, and signaling modification is crucial. Therefore, it's essential to secure both VoIP signaling messages and media streams.

MX-ONE supports the following security measures:

• Secure Real-time Transport Protocol (SRTP): Protects media streams.
• Transport Layer Security (TLS): Secures signaling messages.
• Flexible security policies: Adaptable to different security requirements.

TLS ensures signaling privacy when exchanging SRTP keys between parties (see MiVoice MX-ONE Architecture). The core principle of the security policy is to determine whether an extension can register for the system. Once registered, calls to other parties are secure from a security perspective.
