I have DVX-2000MS-10 VoiceCenter system installed at a customer with 12 handsets and two DVG-3104 gateways.  One gateway has four lines and the other just one.  During heavy use the 4-line gateway restarts and therefore drops calls.  This happens several times per day.  I swapped gateways to no avail.  The entire systems has the latest November 2008 firmware too.  I also tried changing the two gateways to a static IP outside the DHCP scope and also changed the default IP to match the static IP so its no longer 192.168.0.20.  DLink technical supports is insisting I need to STILL change my DHCP scope to start past 192.168.0.20 regardless.  They also indicated the gateways will restart especially during heavy use if there's an IP conflict with gateways.  I am just not finding any other device on the LAN at 192.168.0.20.  All this just doesn't make sence since no else is reporting similar issues in this forum as I think there would with 192.168.0.20.  My switch is an unmanged 16-port gigabit switch.  Perhaps I should get a managed switch?  Anyone have suggestions other than what D-Link is telling me to do?

We are seeing similar issues and it goes to an unstable point after the who knows why Voice Center rebbot that happens every day, so every morning we have to reboot everything.  Then we have to delete and add the gateway.  We are running the latest firmware.  Other issues are that the web interface works only just after reboot.  The inbound calls suddenly dont get forwarded to the Voice Center and the VOice Center cant make outbound calls.

Please call Voice Center dedicated support line at 1-888-404-6262 Option 1 for assistance. We will need to investigate and identify the cause of the reboot.

I have 2 DVG-3104s that have been rebooting themselves durning the day.  This only seems to happen when the are carrying calls.   I have 3 lines on one and 2 on the other, both with static IP addresses.

Did anyone get a solution for this problem?

Well finally, I thought I was the only one having this issue.  I have 2 clients with this phone system, one client has no issues, the other client has MANY!  My first client is smaller and only has 2 lines, they have no dropped call issues.  The other with the problems is larger (15 phones) and 4 lines.  The dropped calls seem to happen when 3 or all 4 lines are in use...

Their main problem is dropping calls in the middle of conversations.  I finally found that the gateway is indeed rebooting periodically causing the dropped calls.  I have swapped to another new gateway and am still having the same problems.  All up to date on firmware and service packs.

At this point they are ready to dump this system and buy something else...

Any help on this would be appreciated...If no help I may have a system for sale, and probably loss of a client.

You can check out my complete reply on another thread, but I think the issue with your 4 line customer may be that the lines are not attached in hunt group order.   I just switched mine to the order of the inbound hunt and the things have stayed on for 21 hours straight.

Hunt order has made no difference.  I tried the right order, tried reverse order, even tried mixing them up.

Let me go back in time...

This system was installed nearly a year ago.  For the first few months it worked great!  Then everything started going down.  I got complaints of dropped calls, but only once in a great while.  I also had call quality issues, but I was able to get those corrected.  Then the dropped calls started getting more frequent. 

About 3 months ago I got a call from the customer who was very unhappy because they were dropping calls multiple times per day.  I verified all software was up to date (which it was) and even swapped out a couple of phones that seemed to be more centered around the drops.  Nothing helped.  After checking everything I finally figured out that it was the gateway rebooting.

I checked the phone lines into the gateway, I actually found that this entire time they were installed in the wrong order.  I had lines 2 and 4 swapped.  I changed the order back to they way it was supposed to be.  Checked the line settings again and let the customer know what i did.

I got a call the next day and they said it was worse than before, now calls were dropping about every hour.  They were getting very frustrated by this time.  I went back and put the lines back (incorrectly) the way they were before (when it worked fine), that did not help.  I tried other orders, even blocked outbound on a couple of lines.  No help.

My last shot was I installed a new gateway (about a month ago).  When I installed it I put the lines in the correct order.  The very next day they dropped calls again, the new gateway was also rebooting.

I was just informed last week that this phone system has been removed and I have lost a customer.  I can't blame them, I was apprehensive when we chose this system and I should have followed my gut.  They were patient for nearly a year working through all of the issues, but in the end this system just did not cut it.  My other customer that has this system is still fine, but they have only 2 lines and only 10 phones, with low call volume.

DLink, we don't have time for you guys to take a month or more to figure out the reboot problems.  If I could do it over again I would have gone with a different system.  Too late now.

Another user here with regularly unscheduled reboots (among other issues like echo and feedback making the speakerphone completely unusable). I have to say that Dlink tech support has done their best to work with me on this system over the phone but there's just no getting around the bad hardware reference design. It's been problematic for about a year now, and we're about ready to cut our losses and get something else. It's not brand specific, as we've also tried replacing the gateway with one from Aastra too. I have 4 lines with mediocre call volume, I'm running the latest firmware, and I've got the phones on a 100 base network. Dlink needs to offer some kind of refund program and recall the phones, I mean, everyone is having this issue (among others). For us, it's over 3K down the tubes, and nothing but frustration to show for it.

My issues with this system never went away either.   They have someone calling dLink trying to get credit for the money they put into the system.

I had them try a Quintum gateway because I thought that would help but it didn't.
