(2009-10-17) Bray Sip Gizmo

Tim Bray has been patching together some voice calls with SIP, Gizmo, Google Voice, and Android, showing an advantage of Open Standards over closed systems like Skype (which can't be combined with other technologies as easily). Anyhow, if you place either a SIP call to my Gizmo5 number, or an ordinary call to my Google Voice number, if Guava is running and I have Internet connectivity, my Android rings.
