Starting from next Calls release we are enabling support for TCP candidates. This means that if no UDP connection is possible, a TCP channel can be used instead as a backup option. The big advantage of this approach is that it can avoid having to deploy and maintain a separate TURN server to guarantee connectivity for clients unable to use UDP for whatever reason (e.g. protocol blocked by firewall).
I am also updating the base image version to the latest ESR since support for the previous one has ended last month.
