Loss of dial tone and calls after 6-8min with ip8100

Hello,

I am having difficulty keeping my Vonage connection up and running. After I boot up the ip8100, I have a dial tone and can make calls for ~6-8 minutes before I lose the dial tone or my call is dropped. The adapter shows no change in status via its LED and resetting it has absolutely no affect on it (I don't think the reset button works). Power cycling the adapter brings it back up for another 6-8 minutes.

MY setup is DSL modem (T-DSL) -> Linksys BEFSR41 -> PC and ip8100. The results of my connection test are below.

Does anyone know if I need to setup my router in a certain way for it to work with the ip8100? Opening ports, assigning something strange? I can't try just the ip8100 without my Linksys because the ip8100 isn't capable of connecting to my ISP (need to prefix and suffix my user name along with the domain name) so I can't rest that. I tried adjusting my lease time but it didn't change a thing. Any input would be appreciated

So, I decided to watch the ip8100 adapter while it was running by slotting another PC into the LAN connection on the adapter. I power cycled the adapter, it made itself ready, and I logged onto it. Everything was fine. So, I made a phone call and sure enough it dropped the call after a few minutes.

At that point, the adapter software became non-responsive and I could no longer address it. The adapter however, maintained its ready light and could page phones. I had previously believed that the reset button on the adapter was broken because pressing it never did a thing. However, in light of this lock-up, which I thought was it simply losing Vonage service, I tried something else. I power cycled it (it took 5 tries for it to actually "boot" and make itself ready) and then reset it. This time, the adapter actually reset itself!

So, based on the fact that I can get service from Vonage and some calls last more than a few seconds, I think I may have a problem with my adapter. Perhaps it is actually locking up for some reason and that is why my calls drop and it is unresponsive. Has anyone dealt with this before? Anyone have some ideas? Firmware is an automatic update so I'm not sure how to attack that front.

I am having the exact same problem, except with a linksys WRT54G. I actually got Vonage to send me a new 8100, hooked it up today, and the same thing is happening: a few 6-8 minute calls, then about two minutes. I posted today to ask for a solution...maybe we need to open a port, QOS, Port forwarding, something...

Hi Chops,

I've tried everything with the darn thing. I assigned the 8100 a static IP, opened it directly to the Internet from behind my router, forwarded all the ports for Vonage to them, etc.. etc... The best I got was a 38 minute call home.

Vonage finally kicked me up to the Tier II support (all via email) after I explained them the problem the 6th time. They are fast on the replies, but they aren't really very useful. They, of course, told me to call my ISP because it was the issue after they told me to reboot my TI Motorola Voip adapter and disconnect any 2.4GHz phones I was using. Of course, that wasn't even my setup and I told them to read my emails before giving me useless advice for a setup I don't own.

We'll see how their next level of support is. The fact that my connection results look good (I believe) and that the adapter locks up even when it isn't connected to the Internet really make me suspect the hardware. The lock is so hard, that I can't understand what else it could be given the absence of an Internet connection.

Let's home somebody here has some ideas!
