For more details, see the RMX 2000/ 4000 Administrator’s Guide.

To start ongoing conferences and monitor their status see the RMX 2000/4000 Getting Started Guide, Chapter 3 “Basic Operation”.

Connecting to a Conference Directly or via Entry Queue

The RMX is shipped with pre-configured default conferencing entities that can be used to dial in and start conferences. Default (Transit) Entry Queue ID: 1000, default Meeting Room IDs: 1001, 1002, 1003, and 1004.

H.323 Participants

H.323 participants dial:

[MCU Prefix in Gatekeeper][Conference or Entry Queue ID/Name].

For example, if the MCU prefix in gatekeeper is 925, you can dial to the default (Transit) Entry Queue by entering 925 or 9251000 and be routed to Meeting Rooms by entering its ID (i.e. 1001, 1002, 1003 or 1004). You can connect directly to one of the default Meeting Rooms, by dialing its number, for example: 9251001.

Alternatively, you can use the Entry Queue or conference name to connect directly to the conference. For example, if the conference name is Maple_Room, the participant can dial: 925Maple_Room.

SIP Participants

For SIP participants the dialing string is composed of the conference routing name as registered with the SIP server and domain name in the following format: conference_name@domain_name.

For example, if the conference name is Maple_Room, the participant dials: Maple_Room@polycom.com.
