SIP phones need to re-register every once in a while to tell the server where it can be reached. If you have a soft phone on a laptop that you move from network to network - home, office, airport, Barnes & Noble etc - you want to be reached on the IP address you use there. SIP registration keeps the server up-to-date with your hectic life :-) /Olle --- Astricon - where you meet Asterisk friends and re-register with them by exchanging updated business cards! http://www.astricon.net/2005 - register today! _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
