Configuring the MCU for Federated (ICE) Dialing
The MCU Default IP Network Service must be configured to work with the Office
Communication Server/Lync Server as the SIP Server and the MCU user defined in the
Active Directory must also be defined in the MCU ICE environment parameters to enable
remote dialing in a federated (ICE) environment, .
To configure the MCU for ICE Dialing:
1 In the RealPresence Collaboration Server Web browser, in the RMX Management pane,
expand the Rarely Used list and click IP Network Services ().
2 In the IP Network Services pane, double-click the Default IP Service (, , or )
entry.
The Default IP Service - Networking IP dialog box opens.
3 Click the SIP Servers tab.

2010 is specified and the Server Domain Name is the same as defined in the OCS/Lync
Server and in the Management Network for the DNS.
The procedure described here assumes that the MCU is configured to work in Microsoft environment
as described in "Configuring the RMX 1500/2000/4000 for Microsoft Integration” on page H-36.
