Question

Can we limit the UDP port range to only a specific range, for example 30000-39999 only?

Applies To

• Vonage Video
• UDP Port Range
• Network Connectivity Requirements

Answer

Vonage recommends UDP ports 1025 - 65535 for a better experience. Using UDP ports 1025 - 65535, the session can establish a direct connection to send media data over UDP which results in lower latency and improved call quality.

UDP ports 1025 - 65535 are optional but recommended. However, UDP port 3478 is required. If UDP port 3478 is blocked by the firewall, media may not be able to go through our TURN servers.
