One of the conference properties you can optionally specify in a template is the
conference IVR service that the RMX MCU should use. For most purposes, you
shouldn't do so. RMX MCUs have two defaults, one for conferences with
passcodes and one for conferences without passcodes, and automatically use
the right one for each conference.
If you do choose to override the default and specify an IVR service, it's up to
you to make sure that the IVR service you select is appropriate for the users
whose conferences will use this template, and that it's available on the MCUs
on which those conference may take place. See your Polycom RMX
documentation for information about conference IVR services. This feature is
not supported on Tandberg Codian MCUs.
On the Conference IVR tab of the Add Conference Template and Edit
Conference Template dialog boxes, the list contains the names of all the
conference IVR services available on the currently connected MCUs. If an IVR
service is only available on some of the connected MCUs, its entry shows how
many of the MCUs have that IVR service (for instance, 2 of 3).
If a template specifies a conference IVR service, the system will put
conferences using that template on the least used RMX MCU that has that
conference IVR service. If there are none, it falls back to the default conference
IVR service.
One of the conference features you can optionally enable in a template is
cascading, which makes it possible for a conference to span RMX MCUs.
Cascading a conference across multiple MCUs can conserve bandwidth and is
especially useful when using WAN links. Participants can connect to MCUs
that are geographically near them, reducing network traffic between sites to a
single link to each MCU.
Cascading does, however, impact the quality of the conference experience.
Note
Cascading is supported only for RMX MCUs and only in H.323. The Polycom DMA
system must be configured to support H.323 signaling in order to enable cascading.
For conferences with cascading enabled, the system selects only RMX MCUs that
have H.323 signaling enabled.
If you have a Polycom CMA 5000 system in your network, you can enable
cascaded conferences with these steps:
On the Polycom CMA system, create site topology data defining the sites,
1
site links, and MPLS clouds in your network, and the subnets in each site.
On the Polycom DMA system, integrate with the CMA system to obtain
2
its site topology data. See "CMA Integration" on page 49.
