Ad Hoc Conferencing

Gateway to Polycom® Distributed Media Application™

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

Hoc Conferencing and External Database Authentication" on page D-1.

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.
