Thanks for your response. I did go through couple of documents and found the below in Dev net:
"If an agent drops from or transfers the call that the supervisor is monitoring, the silent monitoring session ends."
When you say "just based on how you have to configure and trigger it" does that mean we can configure in CUCM to monitor the transferred calls ?
Do i need to test by silent monitoring an Agent and try transferring ?
HI Anthony thank you so much for your brief explanation and apologies for late response. Your response will be helpful for me to convince my customer.
You didn't mention the platform/version, but the monitoring is typically done by monitoring the agent's specific phone using BiB, so if they transfer the call, the monitoring session should end.
