In-Depth Information
Show Line Group Member DN in finalCalledPartyNumber CDR Field: For calls
to Call Hunting systems, this parameter determines whether the Hunt Pilot number or
the DN that picked up the calls is recorded in the CDR. The default is False (the Hunt
Pilot number is recorded, not the DN).
Add Incoming Number Prefix to CDR: This parameter controls whether the in-
coming prefix (several are defined in the service parameters) is added to the calling
party number in CDRs. Prefixes added to an inbound call are always recorded in
CDRs; this setting controls whether prefixes are added to CDRs if they are added to
outbound calls. The default value is False .
CAR Tool Users
The CUCM CAR tool allows three types of users to have access to the tool:
Administrators can use the tool to access all reporting features to build reports for
system performance analysis, load balancing verification, and troubleshooting pur-
poses. Any end user or application user can be given administrator access to the CAR
tool by making them a member of the Standard CAR Admin Users Group.
Managers can generate reports for users, departments, and Quality of Service (QoS).
Managers are defined by the Manager User ID field in CM Administration: If User
A's ID is selected in the Manager User ID field on User B's configuration page, User
A can run Manager reports on User B. Managers can set up automatic reports to be
delivered to their configured mail ID.
Users can generate a billing report for their calls. Users can generate reports for a spe-
cific date range and can have the system e-mail the report. Users must be members of
the standard CCM End Users Group to access these reports, and the devices they
want to generate reports for must be associated with their account.
CDR and CMR Architecture
CDRs are generated by CUCM servers that are processing calls (those that are running the
CallManager Service). The CDRs contain information about the called and calling num-
bers, the time/date stamp for connect and disconnect, and why the call was disconnected.
CMRs contain information about latency, jitter, packet loss, and the amount of data sent
during the call. Each call may generate several CDRs and CMRs. The call processing
nodes collect the CAR data (the collective term for CDRs and CMRs) in a local log and
periodically upload them to the CDR repository node using SFTP. The repository node
runs the CDR Repository Manager Service, which is responsible for maintaining the CDR
and CMR files, managing the disk space used by the CDR data, and sending the files to
(up to) three configured locations (typically, these are third-party billing servers).
CAR System Parameters
The CAR system requires some setup to function most effectively. The following tasks
need to be completed:
Configure Mail Parameters so the CAR system can send reports and alerts by e-mail.
