• Same Conference Parameters are defined in the Profile of the conferences participating
in the cascading topology
— Conference line rates should be identical

Same encryption settings
• DTMF codes should be defined with the same numeric codes in the IVR services
assigned to the cascading conferences
• DTMF forwarding is suppressed
• The video layout of the link is set to 1x1 by the appropriate system flag.
• When the Mute Participants Except Lecturer option is enabled in the Conference
