Hello-- I've installed a few X-Lite softphones on windows machines, and am playing with the settings. I've written before about this, and since have discovered that the X-Lite has an option to turn off registration, which I have set, because I bumped into a letter from Mark, saying that Asterisk doesn't do registrations yet. And, without such on the X-Lite, I can still dial out, and get calls. And, best of all, no 60-second repetition of the same error message over and over and over to fill up the logs and the screens. My question: What is this feature? What is SIP registration? murf
