IP Network Services enable the RealPresence Collaboration Server to function within IP network 
environments. They include the network parameters required for the MCU to connect with other IP devices 
on the same network or outside the network through a firewall. 

Two types of IP Network Services are defined for the Collaboration Server:

● Management Network Service 
● Default IP Service (Conferencing Service)

Connection between the Collaboration Server management applications (Web Client And RMX Manager) 
and participant connections to conferences (Dial in, dial out) are supported within the following IP 
addressing environments: IPv4, IPv6 and IPv6 & IPv4

When IPv4 is selected, IPv6 fields are hidden and conversely when IPv6 is selected, IPv4 fields are hidden. 
When IPv6 & IPv4 is selected both IPv6 and IPv4 fields are displayed.

For more information on IPv6, see 

When the RMX is configured for IPv4 and IPv6 Addressing, the addition of the sdp-anat option tag in the 
SIP Require and SIP Supported headers allows a mixture of IPv4 and IPv6 addressing to be specified by 
the Session Description Protocol (SDP). For more information see 

For the purposes of comprehensive documentation, all screen captures in this chapter pertaining to 
Collaboration Servers (RMX) 1500/1800/2000/4000 show the dialog boxes as displayed with IPv6 & 
IPv4 selected.
