Supporting Remote and Federated Users in Office Communications Server

ICE Environment

To enable the remote and Federation connections the following operations must be
performed:
• Create an Active Directory account for the MCU that will be used for registering and
operating in the MS ICE environment
• Enable the MCU User Account for Office Communication Server
• Configure the MCU for ICE dialing for more details, see "Configuring the MCU for
Federated (ICE) Dialing” on page H-63.
The MCU can also be set for Matched URI Routing and/or Numerical Dialing to Meeting
Rooms. For more details, see "Setting the Matched URI Dialing Method” on page H-6 and
"Setting the Numerical Dialing Method” on page H-12.

Creating an Active Directory Account for the MCU

The User account created for the MCU is used for registration in the Office Communication
Server and to automatically synchronize with the STUN and relay (Edge) servers.
To add the MCU user to the Active Directory:
1Go to Start > Run and enter dsa.msc to open the Active Directory Users and Computers
console
2In the console tree, select Users > New > User.
To place federated calls between Domain A and Domain B in ICE environment sub domains must be
federated to the main domain or the MCU system must be installed on a main domain.
