    SRTP + TLS 1.3

    Every call, every time

    Enterprise Security, Not an Add-On

    Call encryption is standard on every Big Sky Telecom plan. Not a premium tier feature. Every voice call, video call, and message is protected by default.

    SRTP Voice Encryption

    All voice media is encrypted using Secure Real-Time Transport Protocol (SRTP). The industry standard for protecting voice streams from interception.

    TLS 1.3 Signaling

    Call setup, routing, and signaling data are encrypted with TLS 1.3. This prevents man-in-the-middle attacks on your phone system's control plane.

    End-to-End Protection

    Encryption is applied from your device to the Big Sky Telecom infrastructure. No leg of the call travels unprotected, even over public internet connections.

    Zero Plaintext Transmission

    Big Sky Telecom never transmits voice or call metadata in plaintext. Every packet leaving your device is encrypted before it touches the network.

    Certificate-Based Authentication

    Big Sky Telecom uses certificate-based mutual authentication to verify that calls connect to legitimate infrastructure. This blocks impersonation attacks.

    Audit Logs & Compliance Reporting

    Every call event is logged with timestamps, endpoints, and encryption status. This provides the documentation trail required for compliance audits.

    Big Sky Telecom call encryption supports compliance requirements across multiple regulated verticals.
