Typically the replyTo field contains the name of the reply queue. And 
you use that as the routing key of the reply message and send that 
message to the default exchange.

The default exchange mainly exists for this and similar use cases. You 
can think of it as providing a convenient mechanism for addressing 
queues directly, i.e. any message sent to the default exchange is routed 
to the queue named in the routing key.
