Lifesize Cloud is enjoying tremendous growth. To ensure sufficient capacity to handle the increasing call traffic on the service, we will be expanding the UDP port range used. Going forward we will use ports 10000 to 28000.
If your company has implemented firewall policies that are specific to the port numbers used in Lifesize Cloud, you must update your policy to include the new expanded range (10000 to 28000). Please refer to the Opening ports page under Configure Lifesize Cloud in Lifesize Cloud Help for additional information.
If you have no firewall policies specific to the port numbers used in Lifesize Cloud, then there is no action necessary on your part.
To ensure uninterrupted service, please be sure to make any necessary changes to your environment before we enable the usage of these ports on Friday, July 1, 2016.
