I started having the same problem today, although I upgraded router last week with NO problems until now. Spent an hour with Vonage tech support and got nowhere. Finally a supervisor told me they had recieved several other calls from customers complaining about the same thing, and they all seemed to be using a dlink router.
Tried changing the TPC & UDP settings mentioned in this post and IT WORKED! ...Thanks guys!!!!!
DLINK DIR 655 H/W: A3 F/W: 1.10 (UPGRADED TO 1.11)
Newer D-Link routers have a "feature" called Application Layer Gateway. It basiclly re-writes the packets of vertain protocols to make it appear that its not coming from behind a router. But you still are behind a router and special handling is needed for streaming data connections.
Now here is a problem. Some models (DI-625) have it but aren't documented and cannot be disabled. Others have it (DIR-655) but depending on the firmware version can't be disabled unless you upgrade the firmware to the latest version. Note that if you need to upgrade your firmware, you should make a note of any settings you have in the router, such as your connection type (if you use PPPoE, for example) and wireless security settings as firmware updates tend to wipe out settings. Yay D-Link!
Anyway, go into the Advanced section and then Firewall. Uncheck SIP. Save settings. Reboot.
(1) I wouldn't uncheck the SIP box, as that provides stateful inspection of packets -- a very useful firewall tool. YOu'll decrease how well the router works as a firewall by unchecking this box.
(2) I had the same problem as reported in this post, although before I found this post, I contacted Vonage. They "refreshed some settings" for my device, I did a hard reboot of the adapter, and the problem went away. So to some extent, Vonage can correct this problem on their end.
FWIW, I've had to contact Vonage tech support twice in the past 90 days (this issue, and also one line wouldn't "undo" it's call forwarding), and had great success on both counts. This last time I did everything via email, and within 48 hours the problem was resolved. The first time I called up tech support. The gentleman in India was very nice, and had me try certain things. When that didn't work, he sent me to New Jersey. This guy was ruder (it was 3 AM his time on Sat night), but got my problem fixed right away.

You don't need to uncheck the "SPI" selection to fix this issue. Only change the settings I mentioned in the earlier posts.

Actually, changing the settings as suggested in the 2nd post of the thread is the settings that will decrease security.
SIP is session initiation protocol, the protocol that Vonage (and many other Voip) providers use to set up calls. SPI is stateful packet inspection. It is a firewalling algorythem that attempts to match data to an existing session. It can be a problem if the processor in the router cannot keep up with the rate of data going through the router, as is often the case with consumer-grade equipment.
The second post of this thread suggests disabling endpoint filtering. What this means is that, once a port is opened, any foreign host can portentially send data into your network through that port. You probablly don't want that.
Application Layer Gateway attempts to make certain applications seem to not be behind network address translation by re-writing the packets that go through the router by replacing the private IP address with your ISP-assigned public IP address.
Why can this be a problem? If you see that the contact address in your packet is a private IP address, you then need to take additional steps to find the public IP address and port the packet came from. Otherwise, if the contact address is public, you should be able to send a response back to where the packet tells you to. Even though ALG makes it appear that the packet isn't coming through NAT, it really is. This is where it becomes a problem. Lets say for example your TA device picks UDP port 10050 to send and receive audio on. Your ALG enabled router changes the contact address in your packets. However, when the packet goes throgh the NAT, the packet really is sent out into the internet over, say, port 21037. The firewall then doesn't accept the response on anything other than port 21037. But your packets are now telling the other end to send the response to port 10050.
The result is that what you are expecting to receive back fails to get to you. With a Voip phone call, you have one (or no) way audio.
What exactly did Vonage do for you to get it working? I'm still confused as to why DIR-655 users suddenly started having issues. Did Vonage change something on their end?
