Ad Hoc Conferencing
• Partially Registered - This status is available only in Multiple Networks configuration,
when the conferencing entity failed to register to all the required Network Services if
more than one Network Service was selected for Registration.
The Entry Queue can also be used for Ad Hoc conferencing. If the Ad Hoc option is enabled
for the Entry Queue, when the participant enters the target conference ID the system checks
whether a conference with that ID is already running on the MCU. If not, the system
automatically creates a new ongoing conference with that ID. The conference parameters are
based on the Profile linked to the Entry Queue. As opposed to Meeting Rooms, that are
predefined conferences saved on the MCU, Ad Hoc conferences are not stored on the MCU.
Once an Ad Hoc conference is started it becomes an ongoing conference, and it is monitored
and controlled as any standard ongoing conference.
An external database application can be used for authentication with Ad Hoc conferences.
The authentication can be done at the Entry Queue level and at the conference level. At the
Entry Queue level, the MCU queries the external database server whether the participant
has the right to create a new conference. At the conference level the MCU verifies whether
the participant can join the conference and if the participant is the conference chairperson.
The external database can populate certain conference parameters.
For more information about Ad Hoc conferencing, see Appendix D, "Ad Hoc Conferencing and
External Database Authentication” on page D-1.
Gateway to Polycom® Distributed Media Application (DMA) 7000
Gateway to Polycom® Distributed Media Application (DMA) 7000 enables audio only
PSTN, ISDN (video endpoints using only their audio channels), SIP and H.323 calls to
connect to the Polycom DMA 7000 via gateway sessions running on the RMX. Each RMX
conference acting as a gateway session includes one connection to the endpoint and another
connection to the DMA. The DMA 7000 enables load balancing and the distribution of
multipoint calls on up to 10 Polycom RMX media servers.
As part of this solution, the RMX acts as a gateway for the DMA that supports H.323 calls.
The PSTN, ISDN or SIP endpoint dials the virtual Meeting Room on the DMA via a special
Entry Queue on the RMX.
For more information, see "Dialing to Polycom® DMA 7000” on page 18-21.
