I am sure she will encounter NAT at least once in either situation. Her room does have a port for telephone but I think she is on her own to get any phone service.

If I had the money to afford Jasomi gear, I wouldn't care about the phone bill I clock up in some hotel. In fact, I could spend hours talking on the outrageously overpriced GSM roaming service and it would still be cheaper than buying Jasomi. Besides, NAT is not the only trouble you will have with SIP when you travel to non-OECD places. Jasomi does nothing to get you past those other hurdles. > I've had very good results using SER with nathelper module.

I could send them on a month long trip where they never stay in the same place twice and they wouldn't get it working once. I have spent hundreds of hours in third world environments trying to get VoIP connections going from ad hoc offices, public places and customer premises. I am not talking from the convenience of my first world infrastructure home or office theorising about why things should work overseas in less fortunate places. I have actually been to those places and the experience is precisely like I said, no buts and ifs whatsoever. Let me give you some examples ... I have been to hotels which had broadband in the room and I paid so much extra for that broadband room that it really didn't make sense because I wouldn't have been able to make up for the extra cost by saving on phone calls. However, I paid for it because I wanted to try it out. In many of those places, you will find yourself behind two levels of NAT. It is also not uncommon to find that they block ports you need or they reset their routers periodically every 60 seconds. For example, many hotels in Hong Kong use a provider specialising in serving hotels and they reset their routers every 60 seconds probably to prevent customers from watching video streams or making VoIP calls because the hotels want to make money on their inhouse services. As you would expect, any services orther than HTTP will be severely impeded. SSH sessions will freeze, tunneling is out of the question and ftp downloads are problematic. Yet IAX connections survived this ordeal usually 15-20 times before the connection terminated. SIP connections never did. In other words, your SIP call will last exactly 1 minute while you can talk about 15 to 20 minutes on an IAX call. And you ain't seen nothing yet if you haven't been to the Middle East and Africa. I was in Saudi Arabia for one of the main ISPs evaluating their options for running a domestic-only VoIP service, so I am not talking about sitting in some hotel trying to make things work on a badly run dialup service. All ISPs in the KSA go through the national internet backbone which is run by the government and like all things there it is heavily restricted. Traditional VoIP won't work unless you get the government backbone to co-operate. For that to happen, you'd probably have to get an invitation to install a system for the royal family. Yet, there is a rather simple trick how you can get a connection going using IAX. I won't reveal this here though for obvious reasons. All I can say is the same trick will not work for SIP. Oh, BTW, tunneling is a no-go there, too. Another interesting environment is Egypt. Things are not restricted there as they are in the KSA, but the infrastructure is mostly unsuitable to do VoIP. ISPs in Egypt are very inventive to overcome the lack of resources they face. You will find this kind of inventiveness in many third world environments. Unfortunately, the things they do will pose challenges that SIP simply cannot cope with in a reliable fashion. The observations you make on Egyptian internet connections are so weird, so plenty and so random that it is impossible to present even only an outline within the scope of a posting like this. So, I will keep this short and just give you a minor non-representative but easy to describe example: I was doing some troubles

Don't mix up the content of different posts. In one post, I explained how I used IAX and ILBC successfully on a sub 20k dialup link in Egypt (that was not a hotel but an office, BTW) and in a different paragraph I mentioned hotels in foreign countries as one of many locations where things can go funny. In another post, I responded to a question whether or not it might be possible to use an IAXy on a 33k or 56k dialup connection. There was no mentioning of any hotels and I did say that I have not used an IAXy myself. My comment that the IAXy *should* work on a 56k link was based on the fact that it supports ADPCM and if you check out the specs of most DSPs which do ADPCM you will find that they do 16, 24, 32 and 40 kbps, although the ITU ADPCM recommendation (G.726) talks about 32 kbps. Which chip the IAXy uses and which modes that chip supports, I guess only Digium can tell you. If you want to be absolutely sure, then you may just want to try it out. In fact, I think it would be very welcome if somebody with actual experience testing the IAXy on the road posted some feedback here.

One exception is some hotels that use a web redirect service to basically authenticate a session "before" the user is allowed to do anything. Examples include some Marriotts, very small number of Holiday Inn Express's, etc. In those cases, at least "one" web attempt must be made before a clear channel is allowed from the dhcp assigned address. The snom is never reconfigured (other then some corporations/institutions don't support dhcp), and just seems to work with an * server on a registered IP. I'm writing this from a hotel that only has wireless, so it doesn't work here.

Also, a note that the dialup connection will add in the neighborhood of 140-170 ms of latency. If this is on top of an already high delay connection you might find the conversation to be more of a walkie-talkie type rather than natural flow, assuming you are using a codec that will function over dialup to begin with. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Considering the IP overhead you wouldn't get it to work over a 33k dialup connection, but it should work just fine on 56k. rgds benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan.

Both take MUCH more bandwidth than dialup can provide. -- Eric Wieling * BTEL Consulting * 504-899-1387 x2111 "In a related story, the IRS has recently ruled that the cost of Windows upgrades can NOT be deducted as a gambling loss." ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

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.

Re: [Asterisk-Users] iaxy vs sipura
the only problem you will have whilst travelling with the iaxy is that it supports only bandwidth hungry codecs. so if you are anywhere in the world where bandwidth is a problem, the iaxy is a nogo On Tue, 2004-09-07 at 14:54, Benjamin on Asterisk Mailing Lists wrote: > On Mon, 06 Sep 2004 22:35:46 -0700, Florin Andrei > <[EMAIL PROTECTED]> wrote: > > I need a cheap simple adaptor for analog phones to use with Asterisk.

Perhaps if you travel only within the US, you may be lucky most of the time but pretty much anywhere else where IP addresses are scarce you will be out of luck. I have been travelling a lot on all inhabited continents, using hotel provided internet connections, internet cafes, client's office LANs, hotspots in public places, cafes, airports etc etc. The most common experience is "SIP doesn't work at all" and the second most common experience is "SIP only works after messing around a lot". Even if you get SIP to work, you are likely to spend so much time on fiddling with settings that it has a negative impact on your schedule. I haven't used an IAXy yet but I run Asterisk on my Powerbook and use IAX to connect back to my company's Asterisk server. That works all the time and is "configure and forget". I assume it will be the same when using an IAXy. The only situation I can think of where the IAXy alone will not work is with hotspots that require you to log in from a web browser in order to activate the service, probably setting a cookie or something like that. In this case you would need to run your IAXy on a NAT provided by your notebook because the hotspot will not give you access unless it sees the cookie or the MAC address of the machine that was used to first sign in. hope this helps regards benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan.

I can't decide between iaxy and sipura. Can you guys help? Which one would you use? (and why?) I feel that iaxy might have an advantage while piercing through NAT firewalls (at hotels and such), because of IAX, but i could be wrong. Or can you recommend something else?
