Multiple Networks
For more details, see "Adding Presence to Conferencing Entities in the Buddy List” on page H-49.
A more complex configuration, in which two Microsoft SIP servers are used (one Lync
Server and one Office Communications Server) is also supported using the RMX Multiple
Networks configuration.
In this configuration, each Microsoft SIP Server is defined in a Network Service of its own
(in this case two IP Network Services are defined). Only one DNS server can be used for all
the RMX Network Services, and it must be defined in one of the signaling Network Services.
One IP Network Service is defined as described for a single Network Service in the
Microsoft environment.
The second Network Service is defined without a DNS server, using the IP address of the
Microsoft SIP Server (Lync or OCS server, depending on the server defined in the first
Network Service) instead.
