Gateway to MCU
RMX Gateway A
Figure 5 Gateway to MCU/ MCU to Gateway Topology
In this topology, an IP participant calls a conference running on an MCU via a gateway
and over an ISDN link.
MCU to MCU
Figure 6 Cascading Between Two MCUs Using an ISDN Link
In this topology, an ISDN participant from conference running on MCU A calls a
conference running on MCU B over an ISDN link.
Content is restricted. When another endpoint wants to send content, the first endpoint
must stop sending content before the second endpoint can initiate or send content.
Endpoints that do not support H.239 can receive the Content using the Send Content to
Legacy Endpoints option.
When a participant joins a conference with active Content, content cannot be viewed by
the new participant. Restart the Content.
Cascaded MCUs/Gateways must be registered with the same Gatekeeper or
neighboring Gatekeepers. MCUs and endpoints must also be registered with
Gatekeepers.
Gateway/MCU calls require definition of IVR Services. For more information see
"Defining the IVR Service for Gateway Calls" on page
