45305: No answer from Participant

This warning appears when Flex tries to connect another participant in a voice interaction and does not receive a media response from that participant. You can see this during actions such as a consult call or warm transfer when the target participant does not answer or is not ready to take the call.

• The participant was inactive and did not answer the call request.
• The participant was marked as available in Flex but was actually absent, so Flex routed the call and it went unanswered. (help.twilio.com)
• The participant could not complete the call because their browser did not have access to a working microphone or audio device. Flex rejects incoming and outgoing calls until the device issue is fixed.

• Retry the operation after confirming that the target participant is active and able to answer the call.
• If this happened during a warm transfer, cancel the consult call and start it again after confirming the receiving agent or queue is ready.
• Make sure agents who are away from their desks are set to Offline or another non-available activity so Flex does not route calls to them. (help.twilio.com)
• Verify microphone permissions, headset connection, and the selected audio device in Flex before retrying the call.
