how can we distinguish missed calls

[rin nguyen]

hi, i am a cisco beginner. and I use Cisco Jabber, i have a question that I hope you can answer: "how can we distinguish missed calls? For example: Customer hangs up when listening to IVR, customer hangs up when ring agent, all agents are busy, agent does not answer calls, customer hangs up when agent holds the phone,..." Thanks for your attention. I look forward to hearing from you.

i using Cisco jabber to connect my CRM Voice, and i have a problem :"i can't distinguish missed call." i try to distinguish when i using Call Disposition Code in Termination Call Detail Table. example: call disposition code: 3 - customer hangs up when ring agent, call disposition code: 6- the customer stamps when the agent holds the machine call disposition code: 19- agent did not answer the call....

I hope I can get some tips or tricks from the Community of Cisco experts and peers. eg I can distinguish missed calls from which tables, from which columns in the table,... have a great day.
