I have set up an asterisk server and can successfully call between extensions using SIP. i wish to be able to call other sip users using URLs such as sip:user at sipdomain.com and have no idea how this works... every time i try it (using X-Lite soft phone), i just get a 404: not found error. Any clues? Cheers Dan -- Dan Goscomb <dang at cashcade.co.uk>
