Creating the Dial-out Link between the Conference Running on the
MGC and the Conference Running on the RMX
If the dialing is done from the MGC to the RMX, you need to define the
cascaded link (dial-out participant) in the conference running on the
MGC.
The dial-out string defined for the participant is the dialing string
required to connect to the destination conference via the Cascade-enabled
Entry Queue defined on the RMX hosting the destination cascaded
conference. The dial-out participant can be defined on the MGC as
template or assigned to the Meeting Room.
In the MGC Manager application, define a new participant as follows:
1
In the Participant Properties - Identification dialog box, enter a
Participant Name
2
In the Connection Type field, select Dial-out.
3
In the Interface Type list field, select H.323.

There are two methods to define the dialing string to the other
conference:
a
Using the MCU's IP Address and the Alias string.
b
Using only the Alias string (requires a gatekeeper).
Method A (If no gatekeeper is used):
In the IP Address field, enter the IP address of the Signaling Host of
the RMX hosting the destination conference.
In the Alias Name/Type field, enter the ID of the cascade-enabled Entry
Queue (EQ), the Conference ID and Password of the destination
conference as follows:
EQ ID##Destination Conference ID##Password (Password is
optional).
For Example:
Cascade-enabled
EQ ID
