Cisco Bug: CSCsz56394 - QoS Detail Report should include Orig and Dest mediatransportaddress_ip
Jan 12, 2016
- Cisco Unified Communications Manager (CallManager)
Known Affected Releases
Symptom: Unable to identify network path or device which is causing voice quality degradation in Cisco Unified Communication networks. Conditions: In large networks it is often difficult to troubleshoot voice quality problems like jitter, one-way or no-way audio, etc. Currently the QoS Detail Report specifies the Orig and Dest Device Names. Historically the CAR QoS Detail Report has been somewhat helpful in isolating points of failure in either the network path between two devices or in a specific device. However, this report is only helpful when the Orig and Dest Devices are the actual devices terminating the audio media. More networks are commonly implementing technologies such as Gatekeeper, Cisco Unified Boarder Element, SIP Trunks, CVP, etc which may perform call signaling but which do not actually terminate the audio media. Having the QoS Detail Report specify the origmediatransportaddress_ip and destmediatransportaddress_ip for each call in a dotted decimal format would allow the CAR tool to be much more useful in helping to analyze and pinpoint a network path or device introducing voice quality problems.
