Defining Dial Out Participants - Polycom RMX 1500 Administrator's Manual

Chapter 14-Network Services
Conferencing
Each conference on the RMX can host participants from the different IP
Network networks simultaneously.

Defining Dial Out Participants

When defining dial out participants, you can select the Network Service
to place the call according to the network to which the endpoint pertains.
If the endpoint is located on a network other than the selected network,
the participant will not be able to connect.
If no Network is selected, the system uses the IP Network Service selected
for reserving the conference resources, and if none is set for the conference
it uses the Network Service set as default.
The IP Network Service is selected in the New Participant - Advanced dialog
box.
