• CUCM CMRs, also called call diagnostic records, hold diagnostic information about the quality of the streamed audio of a call, while CDRs hold endpoint and call control or routing information. in context
• On a new CUCM installation CDRs are enabled by default and CMRs are disabled by default. in context
• CDR repository flat files carry a type tag in the file name that separates CDR from CMR files, as in the example cmr_Cluster1_02_200404061011_6125. in context
• Depending on the call scenario more than one CMR can exist for each CDR, and the number written varies by call type and scenario. in context
• The Release 15 CDR overview states that the CDR records relate to the CMR records by way of two GlobalCallID columns: Global CallID callManagerId and GlobalCallID Called; the second name is most likely a typo for globalCallID_callId, which the field tables and a later passage in the same guide use. inferred in context
• The Release 15 CDR overview names the CMR-to-CDR join columns as Global CallID callManagerId and GlobalCallID Called; the second name is most likely a typo for globalCallID_callId, which the field tables use. inferred in context
• The Release 15 overview lists Cisco Unified IP Phones and MGCP gateways as the endpoints that support CMRs. in context
• The Release 15 CDR overview states that with the Call Diagnostics service parameter set to True the system generates up to two CMRs for each call; this conflicts with the statement that SCCP hold and resume produces multiple CMRs per hold. disputed in context
