Integrating OCS 2007 R2 in Exchange 2010 Architecture

Exchange 2010 UM completes the offering of OCS 2007 R2 with a voice mail solution based on messaging. This requires a tight integration between OCS 2007 R2 and Exchange 2010 UM. Together with the integration of IM in OWA, OCS 2007 R2 can be described as being fully connected to Exchange Server 2010, as shown in Figure 1.

The UM role communicates to the OCS Mediation server using the OCS Pool Name and thus contacts the OCS Front-End server. All signaling communication (SIP) and the voice stream (RTP) pass the OCS Front-End server.

When Office Communicator clients access their voice mail mailbox, they also do not directly contact the Exchange UM server role. Their communication is also handled by the OCS Front-End server.
