What a retarded design limitation. If you need to punch through NAT, you can do it by opening ports (as you discovered), using STUN (if your ATA supports it) or by simply avoiding NAT altoghter. Me? I'd get a Digium IAXY and just be done with it. -- Vice President of N2Net, a New Age Consulting Service, Inc. Company http://www.n2net.net Where everything clicks into place!

I don't have that problem, and I run SIP asterisk on the inside of my LAN. I have Sipura, Cisco and Grandstream equipment on the same lan segment. However, I use switches so the traffic doesn't hit the Ethernet port on the router. -- Vice President of N2Net, a New Age Consulting Service, Inc.

I'm unable to open a ticket with Zoom technical support on the >issue. I seem to have found a solution to the problem I had with a ZyXEL Prestige 2000 series ATA. It looks like these things just can't cope with NAT no matter what you do with Asterisk, STUN servers or SIP Proxies. Specifically the voice quality of the person speaking through the ZyXEL is more chopped up then a diced onion if you're going through NAT. I found two solutions, the first one was to put the thing a public IP address and eliminate NAT altogether. Voice quality was then very good. The second solution that seems to work is to port forward on your NAT directly to the ZyXEL. I forwarded ports 5060 and 50,000 to 65,535 (the range the ZyXEL insists on) and then on the ZyXEL enabled the "Use NAT" option and put in the public IP address of the NAT. On Asterisk I just left everything as for any other device behind NAT. This also seems to produce good quality calls. It's a lot of jumping through hoops for something every other device seems to have no problems with! Hopefully someone from ZyXEL reads this. Interestingly the first thing the ZyXEL tech support wanted to know about was NAT even though I told him the calls were getting through...

I've had pretty good luck with the Zoom X5V Voice Modem so far. It has a built in DSL modem, and a single FXS port. Decent little router, now that the latest firmware is out, but tcp and udp timeouts through NAT seem to be set a little low, so I lose SSH sessions. I bought a dozen and have had bad luck with them. I couldn't keep an ssh session for more than 15 seconds. Trying to update firmware turned two of them into paperweights. I couldn't get the FXS to ever register. Other than that, it looked like a good idea.

I've had pretty good luck with the Zoom X5V Voice Modem so far. It has a built in DSL modem, and a single FXS port. Decent little router, now that the latest firmware is out, but tcp and udp timeouts through NAT seem to be set a little low, so I lose SSH sessions. G729 and G711-Ulaw sound great through it, and it supports no-power pass-through to the analog line. -- Vice President of N2Net, a New Age Consulting Service, Inc.

Re: [Asterisk-Users] ZyXEL Router Terrible Voice Quality
I have been frustrated by a variety of zyxel issues/products and have found the best solution for all of them lies in a cylindrical receptacle that sits beside my desk... - Original Message - From: "aza" <[EMAIL PROTECTED]> To: "Asterisk Users Mailing List - Non-Commercial Discussion" Sent: Thursday, April 14, 2005 11:28 AM Subject: [Asterisk-Users] ZyXEL Router Terrible Voice Quality Hi, Has anyone found a solution for the terrible voice quality when using the ZyXEL 2002 units? I have a couple connecting into my asterisk box but the calls are so chopped up and broken that you can't have a conversation. The same router connected to FWD gets crystal clear calls. FWD say they only support G711 which is the codec the calls were using to my asterisk box so it's not a codec issue. Apparently no other settings, apart from the account info were changed, from connecting to FWD to my asterisk box so that would rule out things like silence suppression. Any ideas?
