I have vonage hooked to one of the LAN ports on my DIR-655 I also have the vonage adapter in the DMZ. When making or receiving calls every few seconds I get a drop in audio. I called Vonage tech support and they told me to use port forwarding. If a device(vonage) is in the DMZ dosen't that mean that everything passes through it regardless if port forwarding is on or off?

Anyway, Sharepoint is off QOS is still on. Vonage has a static IP address but I am still getting this problem. I am not sure what to do. I may just have to give up on vonage.

Thanks

I'm not a Vonage user but check this link out to see if this applies.

Hi,

I have a vonage box off one of the LAN ports and it runs fine as it is...no QoS..no DMZ....  I did do a DHCP reservation for the vonage box, but I have no drops at all....

Did you turn QOS turned off?

I have QoS off completely.... no traffic shaping etc....

It could be your ISP. Run the VOIP test on this site, http://myspeed.visualware.com/index.php. And see what your line is like.

When I had Comcast with Vonage I had all kinds of problems with echos and people not being able to hear me. After I switched to Qwest it works great even though the line speed is slower.

Another test you could try is have just your Vonage adapter plugged directly into your modem (no DIR-655). See if you get the same issue. If you do, then you know it is not the 655.

I had one more idea. Some ISP's modems have firewall software installed on them. If yours does it could be the problem.

I also use vonage and the only thing i did was to reserve the ip, no other changes. no QoS (it is set to enable/auto) and not in the DMZ. works fine.

I have Cable modem (Motorola) to Linksys (Vonage 2 lines) to the Internet port on the DIR-655.  All home PC's are in the DIR-655's Ethernet ports.  Vonage said to build it this was so the Vonage router has control, and voice calls would take president over data.
The problem I'm having now is getting access to a new wireless IP camera from outside of the home network.  I think the problem is I virtually have two networks, one inside the other; or not, I'm not an expert by any means.  IP numbers in the Vonage router are 192.168.15.xxx in the DIR-655 it's 192.168.0.xxx.  This prevents me from doing some of the stuff suggested here.  
Any suggestions would be appreciated!

i have qwest dsl to a dir-655 (1.34NA), then a vonage device, a desktop, and a blue-ray player connected to the ethernet ports, and four laptops on the wireless.  for the past week the upload and download speeds were way down, from 6Mbps/800Kbps, to 0.5Mbps/35Kbps.  the VOIP (vonage) audio was terrible, with up to 4sec of delay, and severely broken audio.  However, with a laptop directly connected to the DSL modem, connections speeds were normal (6Mbps/800Kbps)

i have been scouring the help sites - running all manner of troubleshooting - i tried port forwarding, QOS, DMZ, disabling SIP, and multiple hard and soft reboots.

Today i tried a hard reset of the DIR-655 (using the reset button, and after saving the configuration file) - then i immediately uploaded the saved configuration file.  Now all is back to normal - VOIP is good, and connection speeds are normal.

Any ideas why the DIR-655 would bog down (not cleared by hard or soft reboots), but would recover with a hard reset?

thanks
