Allen,

You can delete the trigger 'Notify when guest connects to unconnected support or meeting session' to eliminate these emails.

 What extensions do you have installed on your instance?

(go to Administration Page->Extensions to check)

It looks like you may have an extension installed that is causing that dialog to appear.

You can receive the one-time password via text messages by configuring as email and using the format for your provider:

Unfortunately, this isn't technically possible at this time, as the Host client does not have awareness of the web server.

You can download videos directly from the Audit page by clicking the Download Video link:

Also, we have an updated extension available if you want to automate this:

We have added a delay in version 19.0 that keeps the machine in the session group for 600 seconds (by default) once the Chat tab is selected. 

The value is AcknowledgeMessageDelaySeconds.
