Cisco Call Management Records Field Descriptions
This chapter describes the field descriptions of the Call Management Records (CMRs). The chapter contains the following information:
CMR Field Descriptions
Table 8-1 contains the fields, range of values, and field descriptions of the CMRs in the order in which they appear in the CMR.
Table 8-1 CMR Field Descriptions
cdrRecordType
0, 1, or 2
This field specifies the type of this specific record. The following valid values apply:
•
0—Start call detail record (not used)
•
•
Default - For CMRs, this field always specifies 2.
globalCallID_callManagerId
Positive Integer
This field specifies a unique Cisco Unified Communications Manager identity.
This field makes up half of the Global Call ID. The Global Call ID comprises the following fields:
•
•
All records that are associated with a standard call have the same Global Call ID in them.
Default - Ensure this field always is populated.
globalCallId_callId
Positive Integer
This field specifies a unique call identity value that gets assigned to each call. The system allocates this identifier independently on each call server. Values get chosen sequentially when a call begins. Each call, successful or unsuccessful, receives value assignment.
This field makes up half the Global Call ID. The Global Call ID comprises the following two fields:
•
•
All records that are associated with a standard call have the same Global Call ID in them.
Default - Ensure this field always is populated.
nodeId
Positive Integer
This field specifies the server, or node within the Cisco Unified Communications Manager cluster, where this record gets generated.
Default - Ensure this field always is populated.
callIdentifier
Positive Integer
This field identifies the call leg to which this record pertains.
Default - Ensure this field always is populated.
directoryNumber
Integer
This field specifies the directory number of the device from which these diagnostics are collected.
Default - Ensure this field always is populated.
dateTimeStamp
Integer
This field represents the approximate time that the device goes on hook. Cisco Unified Communications Manager records the time when the phone responds to a request for diagnostic information.
Default - Ensure this field always is populated.
numberPacketsSent
Integer
This field designates the total number of Routing Table Protocol (RTP) data packets that the device transmits since starting transmission on this connection. The value remains zero if the connection is set to "receive only" mode.
Default - 0
numberOctetsSent
Integer
This field specifies the total number of payload octets (that is, not including header or padding) that the device transmits in RTP data packets since starting transmission on this connection. The value remains zero if the connection is set to "receive only" mode.
Default - 0
numberPacketsReceived
Integer
This field specifies the total number of RTP data packets that the device has received since starting reception on this connection. The count includes packets that are received from different sources if this is a multicast call. The value remains zero if the connection is set in "send only" mode.
Default - 0
numberOctetsReceived
Integer
This field specifies the total number of payload octets (that is, not including header or padding) that the device has received in RTP data packets since starting reception on this connection. The count includes packets that are received from different sources if this is a multicast call. The value remains zero if the connection is set in "send only" mode.
Default - 0
numberPacketsLost
Integer
This field designates the total number of RTP data packets that have been lost since the beginning of reception. This number designates the number of packets that were expected, less the number of packets that were actually received, where the number of packets that were received includes any that are late or duplicates. Thus, packets that arrive late do not get counted as lost, and the loss may be negative if duplicate packets exist. The number of packets that are expected designates the extended last sequence number that was received, as defined next, less the initial sequence number that was received. The value remains zero if the connection was set in "send only" mode. For detailed information, see RFC 1889.
Default - 0
jitter
Integer
This field provides an estimate of the statistical variance of the RTP data packet interarrival time, measured in milliseconds and expressed as an unsigned integer. The interarrival jitter J specifies the mean deviation (smoothed absolute value) of the difference D in packet spacing at the receiver, compared to the sender for a pair of packets. RFC 1889 contains detailed computation algorithms. The value remains zero if the connection was set in "send only" mode.
Default - 0
latency
Integer
This field designates value that is an estimate of the network latency, expressed in milliseconds. This value represents the average value of the difference between the NTP timestamp that the RTP Control Protocol (RTCP) messages indicates and the NTP timestamp of the receivers, measured when these messages are received. Cisco Unified Communications Manager obtains the average by summing all estimates then dividing by the number of RTCP messages that have been received. For detailed information, see RFC 1889.
Default - 0
pkid
Text String
This field identifies a text string that the database uses internally to uniquely identify each row. This text string provides no meaning to the call itself.
Default - The system always populates this field with a unique ID.
directoryNumberPartition
Text String
This field identifies the partition of the directory number.
Default - Empty string, "". This field may remain empty if no partition exists.
deviceName
Text String
This field identifies the name of the device.
Default - Empty string "". This field may remain empty if no device name exists.
globalCallId_ClusterId
Text String
This field designates a unique ID that identifies a single Cisco Unified Communications Manager, or a cluster of Cisco Unified Communications Managers.
The system generates this field during installation, but Cisco Unified Communications Manager does not use it: globalCallId_ClusterId + globalCallId_callManagerId + globalCallId_callId.
Default - Ensure this field always is populated.
varVQMetrics
Text String
This field contains a variable number of voice quality metrics. This field comprises a string of voice quality metrics that are separated by a semicolon.
The format of the string follows:
fieldName=value;fieldName=value.precision
This example shows voice quality data, but the names may differ.
"MLQK=4.5000;MLQKav=4.5000;MLQKmn=4.5000;MLQKmx=4.5000;MLQKvr=0.95;CCR=0.0000;ICR=0.0000;ICRmx=0.0000;CS=0;SCS=0"
