?– You can send an IM to multiple individuals at the same time.
?– Within a domain, you can send an IM to a Microsoft Exchange Server distribution list.
You can now also add Microsoft Exchange Server distribution lists as contacts. The
MOC 2007 client allows you to expand your distribution lists through a Web service that??™s
been exposed on the server. This allows you to invite one or more members of a distribution
list group to your IM session. Now your distribution groups of up to 1,000 users can be
expanded, and your IM session can include as many as 100 different people.
Audio and Video
Also new is the fact that OCS 2007 now supports multiparty audio/video (A/V) conferencing.
You and the other users can now specify A/V when scheduling your conference or you
can add audio or video to an existing IM conversation or conference call. Management of
multiparty audio and video sessions is the responsibility of the A/V Conferencing Server.
Where the A/V Conferencing Server is located doesn??™t really matter. It can be colocated
with the pool Front-End Server or deployed in the pool on a separate computer for greater
scalability. Keep in mind, though, that when deployed on a separate computer, the A/V
Conferencing Server can support up to 250 participants within a single session.
As mentioned earlier, OCS 2007 also extends audio conferencing and videoconferencing
to external users. The Audio/Video Edge Server performs as a relay for audio and video
traffi c through your enterprise network and corporate fi rewalls.
