• CUCM generates CMRs according to the Call Diagnostics Enabled service parameter, whose values are Disabled, Enabled Only When CDR Enabled Flag is True, and Enabled Regardless of CDR Enabled Flag. in context
• CUCM writes one CMR for each IP phone involved in a call or for each MGCP gateway. in context
• For hold and resume on SCCP devices, CUCM generates multiple CMRs, one set per hold, so a call can carry more CMRs than one per endpoint. in context
• CUCM stores end-of-call audio and video metrics in CMRs for incoming and outgoing SIP trunk calls through CUBE or SIP IOS gateways. in context
• The Release 15 Call Management Records chapter describes CMRs as storing the quality of the streamed audio and video of the call. in context
• With Call Diagnostics Enabled set to Enabled Only When CDR Enabled Flag is True, CUCM generates CMRs only while the CDR Enabled Flag service parameter is True; with Enabled Regardless of CDR Enabled Flag it generates CMRs whatever that flag says. in context
• The Call Diagnostics Enabled service parameter controls CMR generation and has three valid values: Disabled, Enabled Only When CDR Enabled Flag is True, and Enabled Regardless of CDR Enabled Flag. in context
• When CMRs are enabled, CUCM writes one CMR for each IP phone involved in the call or for each MGCP gateway, so each endpoint in the call produces its own CMR. in context
• For hold and resume calls on SCCP devices CUCM generates multiple CMRs, the number depending on how many times the call is put on hold. in context
• CUBE sends call statistics in a P-RTP-Stat header in a BYE or in the 200 OK to a BYE, and CUCM uses it to update CMRs for SIP trunk calls. in context
