Every time you send a message with Signal, you inform the server which user the message is for. Thus, the server can remember (sending IP, target phone number) pairs and, for similar reasons, (phone number, IP of the user when retrieving messages) pairs. We rely on the server to discard this information; if not discarded, it reveals the social graph and the phone number<->IPs used mapping.
