Dear all, I've recently installed Asterisk and am trying to understand where exactly Asterisk 'fits' in my VOIP architecture. Can/does Asterisk work as a proxy? (or only as a register server?) I am specifically interested in SIP. Could anyone perhaps point me out to a diagram with SIP users and Asterisk to better understand how I should set up my network? Thank you -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20061030/ebd6ae00/attachment.htm

Thanks for the diagram. Is it possible to get a more detailed diagram. I'm looking for something a little more technical. In other words, where does Asterisk stand when inviting a user, when hanging up, when canceling an invitation etc.. Does it go direct from user to user or does it go to Asterisk?

Thank you for the link. Chapter 8 was most useful in explaining the different types of connections (user/peer/friend) as well as the register function such that users may know how to contact another user. However I'm looking for something more specific. For instance, for a normal session termination (i.e. BYE), user1 would send msg BYE to proxy who would then forward it to user2 who would then close the connection. For a cancel request the following messages are exchanged: u1 -> proxy: invite proxy -> u2: arp request u2 -> proxy: arp response proxy -> u2: invite proxy -> u1: trying u2 -> proxy: ringing proxy -> u1: ringing u2 -> proxy: ok proxy->u1: ok u1 -> proxy: ack proxy -> u2: ack <exchange data> u2 -> proxy: bye proxy -> u1: bye In this scenario for instance (where user 2 closes the connection), where does Asterisk fit in? If at all? Does Asterisk behave as the proxy?

Thank you for you responses re: my question on the architecture of Asterisk. Olle, your explanation was especially useful. I still feel like I'm missing a crucial part here. If Asterisk is an endpoint, and according to the example you gave in your response (if u1 hangs up then Asterisk decides to hang up with u2) it is then for a 'bye' message, where would Asterisk come in? Would u1 send a bye message to Asterisk who would then send that message to u2? I'm still a little puzzled as to where it comes in the picture when we're talking about the flow of messages between two users. Perhaps more specifically, why is Asterisk required at all? Is it just to locate users? Thank you so much Jez -------------- next part -------------- An HTML attachment was scrubbed...
