As a reminder to previously announced changes, to ensure sufficient capacity to handle the increasing call traffic on the service, we have expanded the UDP port range used. We currently 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.
