The Chinese mainland USES cloud, which has a poor effect when bandwidth is not limited by ports, and transfers and receives less than 100 in statistics.
Is there any way to solve it？
Expected bandwidth for an Icon is 2 mbps and computers (depending on available resources) around 1.5 mbps. If you are only seeing 100 kbps something between the client and the Lifesize registration server is limiting the bandwidth.
Lifesize terminals have a bandwidth rate of over 3M.
There is no speed limit.
How do I specify the IP of cloud server on the ICON terminal？
As mentioned above by my colleague kpinkham, if you're only seeing 100kbps throughput the issue is likely with the network connection (bandwidth) available between the Lifesize Icon device and our cloud servers. I'd suggest looking at any devices in this path (routers, switches, firewalls etc) and contacting your ISP to investigate further. Unfortunately, it's not uncommon to see local ISPs in mainland China restricting services towards the public internet.
To directly answer your question above, you can restrict the cloud server IP if you wish, but this is not recommended unless working directly with the Lifesize support team for diagnostic purposes only. Artificially restricting the access to only one location compromises the high-availability and redundancy aspects built-into Lifesize Cloud.
