Now that the UC500 has successfully been upgraded to software pack 8 which includes Cisco Call Manager Express (CME) 8.0 and runs the new 15.x train of IOS (which thankfully restored my single number reach (SNR) capabilty), I am cooking up yet another experiment to test (the now Google) Gizmo5 SIP service as an add’l inbound SIP trunk and playing with Google Voice integration. Because I don’t want to quite yet shoulder the expense of SIP service being that I have landline phone services through AT&T (formerly BellSouth) used primary for our alarm system and MagicJack (which is more or less a packaged USB/Internet-based  SIP device that provides dial-tone to analog phones at one time easily hackable for the SIP credentials ;^) used experimentally for long distance, I decided to work with the free Gizmo5 inbound SIP service to explore the SIP on the UC500. You can guess as most Americans, cell phones have taken the place of our home phone. I can imagine in the very near future WiFi (i.e. 802.11?) /IP enabled PDA/smartphones replacing desktop stations/phones…also where IP PBX’s will integrate seamlessly with these SIP-enabled cell phones to finally replace the  clunky, proprietary digital and IP (i.e. SCCP) handsets tied to most of today’s IP-enabled phone systems.
