User experience
• OC 2007 users can use the
full functionality of OC 2007
when communicating with
other OC 2007 users.
• When OC 2007 client users
are communicating with OC
2005 users, they cannot
use the new features in OC
2007.
• After Live Meeting 2007
is rolled out to your users,
they can participate in
on-premise conferences
internally and connect
to these conferences
remotely by using the Web
Conferencing Edge Server.
• RCC is only available to
either OCS 2007 or LCS
2005 users when one
SIP CTI FE Signaling
Server is deployed.
