I'm trying to understand IAX and whether or not it would solve my difficulties:
'The primary goals for IAX were to minimize bandwidth used in media transmissions, with particular attention drawn to control and individual voice calls, and to provide native support for NAT (Network Address Translation) transparency. Another goal is to be easy to use behind firewalls.' <http://en.wikipedia.org/wiki/IAX> This sounds good, as I have a NAT traversal problem, as well as others. I'm not the system admin for my network, and am behind a router and firewall. Skype works ok as a softphone, but I'd rather something like <http://www.grandstream.com/y-286.htm> with which I can use a real telephone. Either an ATA or a SIP phone, I'm not sure yet. In any event, there's no point in buying the hardware until I get the networking sorted. Somehow I need to TUNNEL throught the router and firewall? I was looking at <http://en.wikipedia.org/wiki/STUN> as one way of doing this. The Grandstream FAQ explains how to do this: '5. How do I setup my Grandstream Phone for go2call network? typical configuration is: SIP Server: voip01.go2call.com Outbound proxy: (Should leave it blank, because it's a GW) User ID: xxxxx (your Go2Call PIN number) Authentication ID: same as your User ID Password: xxxxxxx (Your Go2Call password) NAT Traversal: YES (WITHOUT setting the STUN server) 6. How do I setup my Grandstream Phone for FWD service? typical configuration is: SIP Server: fwd.pulver.com outbound proxy: 192.246.69.247:5082 (used only when behind firewall, otherwise leave it blank) User ID: xxxxxx (your FWD account number) Authentication/Login ID: xxxxx (same as above, your FWD account number) Password: xxxxx (your FWD password) NAT Traversal: No (You need to set up your STUN server if you don't have outbound proxy)' <http://www.grandstream.com/FAQ.pdf> However, most everything I read on the subject starts with the assumption that there's physical and administrative access to the router. Neither of those hold for me :( I would like to set this up prior to purchasing the hardware, but I don't even know that it's possible. Again, I don't have physical access to the router, so the ATA would have to connect through the computer, which connects to the router. It's not possible to directly connect any hardware to the router. No, it's not possible to use a switch. thanks, Thufir _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
