Askable uses WebSocket and WebRTC connections through our provider LiveKit to transmit data and media content. All transmissions are encrypted using TLS and DTLS protocols.
To ensure proper connectivity, please configure your corporate firewall to allow
outbound traffic to the following addresses and ports:
Required Firewall Rules:
Host: *.livekit.cloud | Port: TCP 443 | Purpose: Secure WebSocket signaling
connection
Host: *.turn.livekit.cloud | Port: TCP 443 | Purpose: TURN over TLS (fallback
when UDP unavailable)
Host: *.host.livekit.cloud | Port: UDP 3478 | Purpose: TURN/UDP servers for
connectivity establishment
Host: All hosts (optional) | Port: UDP 50000-60000 | Purpose: Direct UDP
connections for WebRTC media
Host: All hosts (optional) | Port: TCP 7881 | Purpose: TCP connections for
WebRTC media
Optimization Recommendations:
For optimal audio and video quality, we strongly recommend allowing access to the
UDP port ranges listed above. Additionally, please ensure UDP hole-punching is enabled (or disable symmetric NAT if applicable).
This configuration allows devices behind your firewall to establish direct connections to our media servers, resulting in improved performance and reduced latency.
