Video iOS 3.0 - Signalling Region Selection API
This release of Video iOS SDK introduces the ability to select the region to use when joining a Room. The default setting uses Global Low Latency (GLL), a latency based routing algorithm that selects the region with the least latency. If you don’t want to use latency based selection, you can specify any of the supported regions to connect to via this new API.
Refer to this guide for more information about region selection.
