Management Console

The MCM Call Processing Service handles the Session Initiation Protocol
(SIP) telephony traffic between the CS 1000 and the Office Communications
Server. The Management Console provides real-time status of the MCM,
Office Communications Server, Primary Network Routing Service (NRS),
and Secondary NRS. It also provides Administrative, Maintenance, and
Configuration tools.

Office Communications Server 2007 provides multimedia and collaboration
features such as Video, Internet Messaging (IM), Presence, White Board,
Application Sharing, and Voice over Internet Protocol (VoIP) capability.
MCM enables SIP VoIP connectivity between the CS 1000 and the Office
Communications Server 2007 and TR/87 authorization functionality required
for the Office Communicator (OC) 2007 Remote Call Control capability.

Telephones in a CS 1000 system can make direct SIP calls to OCS clients
when the dialed number maps to a corresponding user’s Line URI using
LDAP queries to the corporate Active Directory. MCM also allows Office
Communications Server clients to originate ESN and trunk calls to corporate
and external users.

MCM architecture

MCM 3.0 is situated between the Mediation Server and the CS 1000. 3.0
