45313: Transfer Failed

This error means Flex could not complete a transfer request. It typically occurs when the transfer times out before completion or when the underlying Voice API request fails during the transfer flow.

• The transfer request timed out before Flex could complete it.
• The underlying Voice API returned an error while Flex was creating or updating the transfer call.
• You tried to start a warm transfer when the current call was not a live, conference-based call.
• You tried to start a warm transfer while another transfer was already in progress or while your participant was on hold.
• You transferred to a task queue that had not been used in the last 30 days, which can prevent the queue from being available for the transfer flow until it is reset.

• Retry the transfer.
• Before you start a warm transfer, make sure the call is live and conference-based, make sure you are not already involved in another transfer, and make sure you are not on hold.
• If you are transferring to a queue that has been idle for more than 30 days, route an inbound task to that queue first to reset it, then try the transfer again.
• Review the related Voice Call Logs, Debugger events, and Request Inspector details in Console to identify the underlying call error that caused the transfer to fail. (help.twilio.com)
• If the failure happens in a customized Flex deployment, review Flex UI error reports and logs to capture more context around the failed transfer action.
