User's Manual 52. Reporting Information to External Party
• (Gateway Application Only) 'RTCP XR Collection Server' (RTCPXREscIP) -
defines the IP address of the ESC server. Alternatively, if you want to send the
RTCP XR to a specific IP Group, use the PublicationIPGroupID ini file parameter.
• (Gateway Application Only) 'RTCP XR Collection Server Transport Type'
(RTCPXRESCTransportType) - determines the transport layer for outgoing SIP
dialogs initiated by the device to the ESC server.
• (SBC Application Only) 'SBC RTCP XR Report Mode' (SBCRtcpXrReportMode) -
enables the sending of RTCP XR reports of QoE metrics at the end of each call
session (i.e., after a SIP BYE).

52.2 Generating Call Detail Records
The Call Detail Record (CDR) contains vital statistic information on calls made from the
device. The device can be configured to generate and report CDRs for various stages of
the call, including SIP messages and/or media. You can configure when CDRs for a call
are generated, for example, only at the end of the call or only at the start and end of the
call.
Once generated, the device can send the CDRs to any of the following:

Syslog server. The CDR Syslog message complies with RFC 3164 and is identified by
Facility 17 (local1) and Severity 6 (Informational).

RADIUS server. For CDR in RADIUS format, see ''Configuring RADIUS Accounting''
on page
779. For configuring RADIUS servers for CDR reporting, see ''Configuring
RADIUS Servers'' on page 238.
Note: The device reports the IP address of SIP UAs located behind NAT, in SIP
PUBLISH messages for CDRs. During SIP signaling negotiation between it and the
SIP UA, the SIP UA provides its media IP address. However, in scenarios where the
SIP UA is located behind NAT, this IP address is the NAT'ed IP address and not the
SIP UA's source media IP address. The SIP UAs media IP address is acquired only
upon receipt of the first incoming RTP packet, where the device "latches" on to the
RTP media and obtains the IP address of the SIP UA. From this point on, the device
publishes CDRs with this correct IP address instead of the NAT IP address.
52.2.1 CDR Field Description
This section describes the default CDR fields that are generated by the device.
Note: You can customize the default CDR fields if desired. For customizing Gateway-
related CDRs, see Customizing CDRs for Gateway Calls on page 772
. For
customizing SBC-related CDRs, see Customizing CDRs for SBC Calls on page 775.
52.2.1.1 CDR Fields for SBC Signaling
The default CDR fields for SBC signaling are listed in the table below.
A typical SBC session consists of two SBC legs. Each leg generates its own signaling
CDRs. Each leg generates three CDR types: at call start (SBCReportType=CALL_START),
