I love these phones. Cisco did a great job remembering those of us who prefer to use open standards endpoints when they could have closed the SPA line down all together in favor of their Call Manager. They have all the same settings as the old Linksys SPA series phones, plus the added Cisco enhancements such as the popular 7900 series handset shape and enhanced audio. These phones actually make Asterisk look and sound good, something I'm sure Cisco doesn't like. Keep up the good work!
