- Cisco Prime Collaboration Assurance and Analytics: Grade VoIP Calls using SCSR Instead of MOS White Paper
For an environment using Cisco Video Conferencing devices, when running the CAR, CDR > Search > By User/Phone Number/SIP URL. The Media Info value for all records is null.
According to the Cisco Prime white paper, this is expected behaviour:
Note that all audio quality metrics listed in Table 1 are stored in the CMR. For phones that do not generate CMR, such as Cisco TelePresenceï¿½ TC, CE, CTX, and IX endpoints; Jabberï¿½ platforms (all platforms); Cisco IP Communicator; and Cisco Unified Personal Communicator, grading will be ï¿½N/Aï¿½.
