How to Enable UDP on Lifesize

Interview Preparation Technology

For the highest-quality video conferencing available, Lifesize favors UDP to reduce delays and ensure smooth calls every time. In just a few steps, you can have UDP enabled on Lifesize and be well on your way to better meetings and stronger results.

  1. Open Lifesize
    Open the Lifesize web or desktop app to get started. Lifesize supports a wide range of devices and user preferences, with apps for PC and Mac computers, Android and iOS phones and tablets, and a browser-based web app for any devices unable to download applications.

  2. Choose preferences
    Once you’re in the Lifesize app, you’ll want to choose your port preferences. To place calls to other devices through a firewall, you need to configure your firewall to allow incoming and outgoing traffic to the Lifesize system through the reserved TCP or UDP ports.

To minimize the number of UDP ports available for communication, you can restrict the range by changing values in Preferences > Network > Reserved Ports. By default, Lifesize systems communicate through ports in the range 60000 – 64999 for video, voice, presentations, and camera control.

  1. Open proxy settings
    With your preferences in place, it’s time to open your proxy settings by navigating to Preferences > Network > Proxy.

This table is a great resource on the necessary firewall and proxy settings associated with UDP, as you’ll need to configure your firewall to allow outbound access from your network to your UDP ports. If you happen to have third-party integration for approved Cisco® and Polycom® devices, you will be provided with an H.460 server IP address, as well.

  1. Enable UDP
    With UDP enabled on Lifesize, users can make the most of their video calls and conferencing, thanks to 30 frames of video or more per second. This image-refresh interval is so fast, you won’t have to wait for delayed data retransmissions, which means improvements in clarity, consistency, and productivity all in one platform.
