MCM 3.0 configuration 137
The call is routed to the NRS. The invite is sent to the NRS, which returns
a 302, and the CS 1000 sends an invite to the MCM Proxy. At this stage,
the invite includes a special header called x-nt-ocn that contains the actual
number called. Use this header to compare against the Active Directory
map for the user’s Line URI. This method is used to prevent you from having
to program the for each user to determine the correct DN upon which to
terminate the call. The MCM then routes this call to the proper Mediation
Server based on the SIP GW ID provided in the INVITE and the Routing
Table configured on the MCM.
You need not configure each user. Configure only the routing DN, and the
header is automatically injected to identify the called party.
MCM Direct configuration
For small CS 1000 deployments (without NRS), MCM supports Direct
configuration. In this mode, MCM sends an invite from the client directly to
the CS 1000 node IP address specified in the MCM configuration. MCM
does not check CS 1000 availability in Direct mode configuration.
For more information about the various MCM configuration fields, see Figure
45 "MCM configuration window" (page 140) .
