Actually, SIP is peer-to-peer protocol. If you know that a person you want to call is running Ekiga (or any other SIP client) on a machine that has a particular IP, you can make a call to sip:<IP address> and the INVITE will be sent to that IP. In the case of domain names DNS NAPTR and SRV queries are used to determine the IP address(es). Now what's the advantage of calling sip:u...@example.com over sip:u...@home.box.example.com? Because in the latter case you're tied to a particular location(s) that are listed in DNS records. With SIP server in the middle, the INVITE is sent to the server and the server decides where to forward it, those even can be multiple locations at the same time. And once the call has been established, the rest of the communication is peer-to-peer anyway (well it actually depends on various things). -- Ian _______________________________________________ ekiga-list mailing list ekiga-list@gnome.org http://mail.gnome.org/mailman/listinfo/ekiga-list
