/mcpDescription Range of Values Field Name 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 indicate and the NTP timestamp of the receivers, measured when these messages are received. 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 Note CMR records will not show latency for all phone loads. For example, for SIP 9.2.1 and 9.2.2, the latency will not show, as it has not been implemented in these loads. Integer latency 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. Text String pkid Identifies the partition of the directory number. Default - Empty string “”. This field may remain empty if no partition exists. Text String directoryNumberPartition Designates a unique ID that identifies a single Unified Communications Manager, or a cluster of Unified Communications Managers. The system generates this field during installation, but Unified Communications Manager does not use it: globalCallId_ClusterId
