UDP/443 is typically Skype traffic. From http://download.skype.com/share/business/guides/skype-it-administrators-guide.pdf (p.10 section 2.1.2 Operations): "It also uses UDP 443 to test network connectivity." These network probes typically have 18 byte payloads from the client (dst port UDP/443) and 26 byte payloads from the server (src port UDP/443)
