IP address whitelisting

    To ensure that your communication infrastructure doesn’t block communication with Plivo, we encourage you to whitelist these IP address ranges and ports on your firewall for SIP signaling and RTP media traffic.

    API

    Since we don’t support static IP address ranges for the API, you don’t need to whitelist IP addresses for Voice API communication.  The domain to whitelist for Plivo APIs is api.plivo.com.

    Browser SDK client and Call Insights

    We don’t support static IP ranges for the Browser SDK client, Browser SDK fallback client, or Call Insights. You can whitelist their domains.

    • client.plivo.com
    • client-fb.plivo.com
    • insights.plivo.com

    STUN servers for Browser SDK

    The Plivo Browser SDK uses Google STUN servers by default to establish WebRTC media communications.

    • stun:stun.l.google.com:19302
    • stun:stun1.l.google.com:19302
    • stun:stun2.l.google.com:19302
    • stun:stun3.l.google.com:19302
    • stun:stun4.l.google.com:19302

    Callbacks from Plivo

    Some Plivo APIs and XML elements support callback events. To make sure those callbacks are not blocked, allow traffic from these Plivo IP addresses to your web applications (ports defined by you; for HTTPS, default is 443, for HTTP it’s 80).

    These IP addresses are NAT gateway IPs associated with our HTTP(s) OutProxy instance.
