Like I said: I run Asterisk on my Powerbook to do IAX to my company's Asterisk server. Keep in mind though that you don't need to have a Linux notebook to do this. A Powerbook running MacOSX runs Asterisk just fine. This may not be much of an issue for the Linux geeks and techies on the list, but if you have to send sales people and other non-tech folks on business trips and give them something to connect, then probably a Powerbook running OSX will be an easier choice since they get to keep their native MS-Office. If there is sufficient interest, I'll be happy to write an IAX Peering Assistant for OSX so that non-tech folks can set this up by themselves. Anybody interested may drop me an email if they wish. > and with the > asterisk server on the laptop handling the NAT issues, it's pretty much > plug and play anywhere in the world. I've even had mine going when I'm > in a "double-NAT" situation. I have tested IAX with six NAT levels (before we ran out of NAT routers). NAT is no problem for IAX, regardless how many levels. The only challenge are services that require you to sign in using a web browser to set cookies or record MAC addresses of the machine signed in from. This would pose a problem for the IAXy because it hasn't got a browser (not that it should). This problem is of course solved with the above mentioned notebook gateway solution, too. > This overcomes the codec situation with the iaxy mentioned in another > mail in this thread. I'd think that this is not a real problem because those places where bandwidth is a problem are likely the places where you would need to bring your own computer anyway. As for challenging situations ... I have used IAX and ILBC between Cairo, Egypt and Tokyo on what has got to be one of the world's worst dialup connections. I am talking about 3-4 kbps before and 15-18 kbps after replacing the phone wiring in the building. It was so bad that SMTP always timed out and HTTP required you to hit reload four or five times before you got anything in your browser. Yet, IAX/ILBC worked like a Swiss clock. I had many hour long phone calls and the voice quality was almost indistinguishable from first world PSTNs. The only thing that made us notice there was a problem with the connection was occassional lag. SIP never worked once in Egypt, no matter what we tried. SIP is another one of those overengineered things which only work in the most ideal first world situations but become highly unreliable when used in the rest of the world. IAX just works everywhere all the time every time. rgds benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan. NB: Spam filters in place.
