I am trying to set up Customer First Callback so that the system will dial the customer when an agent is available and then connect them. When the system dials the customer, and the call routes to the customer voicemail if they are not available, I have the setting for callbacks for the queue set to transfer to flow for answering machine. I then set up a simple inbound call flow with a message to be played when the customer voicemail kicks in. The problem is that the message is never being recorded. I have a detect silence on the front end of this set to 1 second with a 20 second time out. and it is still not working. Documentation does state that this is possible.
For answering machines, the only available configuration is to transfer the customer first callback to an Architect inbound flow. Settings such as Post Connect Call Analysis, Answering Machine Detection, and Beep Detection are enabled by default.
