In the case above, anything matches. As long as there are messages, the flush/0 function will recursively call itself until the mailbox is empty. That is, Message (any Erlang term) is sent to the process with identity Pid. After sending the message pong to the process "ping", "pong" calls the pong function again, which causes it to get back to the receive again and wait for another message. Now let us look at the process "ping". Recall that it was started by executing: ringing_a (A, B) -> receive {A, on_hook} -> A !

When you send a message to the process, the message is put into the mailbox. The only time this mailbox is examined is when your program evaluates a receive statement.
