RE: [Asterisk-Users] iaxy vs sipura
I run Asterisk on Redhat 8.0 with a VM hosted by Microsoft's Virtual PC which, in turn, runs on Windows 2000 Server. Works like a charm. Can't use Zaptel cards but that's OK for me. I can put it into standby any time and it takes only a few seconds to start up the VM from its saved state and at that time the Linux session (and Asterisk) is available once again.

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.

When I first read the above posts I thought as you did but found through some Googling that v.92 is 56k (53k) downstream and up to 48k upstream. 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

Re: [Asterisk-Users] iaxy vs sipura
I need a cheap simple adaptor for analog phones to use with Asterisk. It should be some kind of configure and forget type of device, to use at the office, or just throw it in a road warrior's bag and use it while travelling, to call back to the mothership For travelling, no SIP based device will be configure and forget. 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. Believe or not, I've been using a snom 200 configured with nat and haven't found any US locations where it doesn't work with a couple of exceptions. 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. But, xlite sort-of-kind-of works in its place. :) Rich ___ 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

If you can use a SIP ALG (or far end NAT traversal device like Jasomi), it will pretty much make the config problems 'disappear'. 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. My setup- SER handles the NAT traversal and external extensions while * handles the office extensions, voicemail and PSTN gw. So far, I have yet to encounter a scenario that doesn't work with this setup. Most of the time, my colleagues can walk into a customer's premise, turn on the Cisco ATA and viola - they can call the office or make PSTN calls. All depends on where they are going. 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 troubleshooting of an IP connection between
