Cisco Cisco Unified MeetingPlace Web Conferencing Guida Utente

Internal web servers limit attendance to users inside your organization’s firewall. 
If you scheduled a meeting on an internal web server but want to open it to a user 
outside the firewall, escalate the meeting in progress from the internal web server 
to an external web server. All users in attendance are automatically moved to the 
external server once the meeting is escalated. New users attending the meeting are 
automatically transferred to the external server.

Before you begin, confirm that the following requirements have been met:

The meeting is scheduled for internal access on a web server that has both 
internal and external access available.

You have the proper privileges to enable this feature: you are the meeting 
scheduler or the contact of the meeting scheduler, or you have System 
Manager privileges.

The meeting is currently in progress.

The meeting does not include video participants. You cannot escalate a 
meeting that includes video participants.

Note the following restrictions:

You will lose any web recording or polls that you started on the internal server 
prior to escalating. 

Users who are not using the full meeting console are not automatically 
redirected. To workaround this issue, inform such users that the meeting was 
redirected to an external web server so that they can exit and rejoin the 
meeting. Rejoining the meeting connects them to the external web server.

From the meeting console, choose Meeting > Allow External Participants.

When prompted, confirm your choice to transfer your meeting.

The meeting console closes and is reopened on the external web server.
