Hello, currently the recording needs to be turned on during each session. Automatic recording was considered, but there are some issues - sometimes it would record unnecessary sessions and most importantly, we always need to give the client chance to end the session if he does not agree with recording. That is why there is cca 5 seconds grace period where user is informed about the session recording where he can disconnect.
Do you have some special use-case where automatic recording would be required? We can always re-consider this feature.
