This means that no port blocking, nor QoS is possible on their box. QOS is not all that useful. It only works in the router for outgoing packets, and if you are sending lots of big packets upstream, e.g. filesharing, then you are going to have problems anyway. Latency is the killer of VoIP and it goes up quickly if your send connection is saturated. By QoS I mean traffic shaping too. If you do use P2P throttle your total upload to about 1/30th bytes per second of your speed in bits per second, e.g. a 256k connection should be no more than 10k bytes per second, and may need to be less, try 7.5 or 5 if you get too much jitter. I am not much of a file-sharer, so I don't know. my router does not know how to QoS, so I am not shaping anything at moment. Having no dialer as it were, means you are using MPLS, which some people have problems with. If it does cause problems, then it will be pretty obvious. People have complianed on this list that HOT only guarentees port 80 (HTTP), but I think they have since gotten better about it. not sure what you mean about port 80 - all ports are working fine. I had issues with a couple of ports a year ago (CVS was one, can't remember the other) - but it was related to Bezeq-int, and not HOT. If you have a router, are you sure it's not doing tunneling (the equivalent of a dialer) already? If it is using DHCP then you really are using MPLS and do not have any tunneling, if you are using an L2TP, PPTP, PPoE, etc connection you are. It's not dialing anything, just DHCP. I insist on this way of connection for the last 5 years, and it works flawlessly. Dialer is only trouble for me. This is only based on what they told me, I will know more tomorrow, and if there is something to update, I will. Update the list either way please. Someone will ask the same question again in a few months and at least they can find a response if they search the archives. It is working now, connected to my own router, as a client. it started working right after plugging in, without any port forwarding (not sure how - permanent connection to the base station?). Then he forwarded UDP port 5060 to the box (I asked why if it worked before, he said just to be on the safe side. Everything still works without it though). Then he wanted port 443 too - for managing the box from outside - but since I am using port 443 to my own machine, he gave up and asked to forward it if they ask me in support. I nmap'ed the box, and it's only open port is 4567, which seems like an HTTP server listening, with htaccess protection. I don't know the user/pw for the box. The box is an AudioCodes MP-202B (http://www.audiocodes.com/products/mediapack-20x). --yuval signature.asc Description: This is a digitally signed message part. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

The ad detailed the various benefits of using them as a land line phone provider and as an ISP. They had several plans which can either include VoIP only or Internet and VoiP. The VoIP part can either be 40% (or less) calls to cell phones, or no limit on the relative amount of calls to cell phones versus other phones. AFAIK you get an incoming number in the 07 range instead of the 054 (anyone actually know?) In order to use their service you have to buy an 800 NIS box (which can be spread out over 36 months) and provide your own aDSL line or HOT connection. I do not think you can bring your own box, as it were or connect to them via SIP. I don't know anyone who uses Orange as their landline ISP nor their VoIP services, so comments good or bad would be appreciated.

Re: OT: Bezek via netvision
Hi, I'm using this service. If your infrastructure (HOT/ADSL) is reliable, it works pretty reliably as well. They give you the AudioCodes MP202 adapter, as someone has already mentioned. One thing to note is that they put this adapter in front of your PC / router (i.e. it connects to the modem, and the router connects to it), and it takes your public IP to itself and performs NAT. They don't give you the password for the administrator account on the device so basically you lose your public IP, for what it's worth. This is absolutely ludicrous, to me. They set it up in DMZ mode so that incoming connections are forwarded to your router / PC, but if your internal IP changes for some reason, you need to bug them to reconfigure their box. If you have anything at all that requires a public IP anyway (dynamic DNS?), you're out of luck. Another thing is that they set up traffic shaping on this box so that the VOIP calls are not affected by heavy traffic, and the speed degradation is quite noticeable. Bottom line, the calls are cheap, but it screws with your Internet connection in various ways, and it's basically only as reliable as your connection -- and let me tell you that you don't realize how unreliable Internet infrastructure is here until you put your phone on it. If I were offered this deal now I wouldn't go for it. --Alex - Original Message From: Valery Reznic valery_rez...@yahoo.com To: linux-il. linux-il@cs.huji.ac.il Sent: Wed, February 17, 2010 5:16:29 PM Subject: OT: Bezek via netvision Hi, list Recently Netvision representative contacted me and offered to use Netvision instead of Bezek as my phone provider Do you have any experience with them ?

No, but AFAIK they give you a box which connects to your aDSL line or cable modem. This means that your phone service works less often than the entire combination of your internet connection and your ISP and so on. Good if it is cheap, but keep a cell phone for emergencies. Note that HOT's 077 service is not VoIP, it runs on a different subchannel than their internet service and is much more reliable. 012 and Orange have similar offerings. Orange's deal includes calls to cell phones, so it may be better for you. Geoff. I was using HOT's 077 number for four years. Fax works and the call quality was excellent. However, the tech support are idiots and there were a lot of times when we had no phone service, sometimes days. We ditched them for Bezeq a year ago. More reliable, better tech support, negligible price difference. Note that we do not have a television, so the package deal was only telephone and internet. -- Dotan Cohen http://what-is-what.com http://gibberish.co.il Please CC me if you want to be sure that I read your message.
