Vonage Yes, I am using the Cisco ATA-186. It's probably one of the first versions, if that

Yes, I am using the Cisco ATA-186. It's probably one of the first versions, if that makes a difference. (I've had Vonage for more than a year.)

I'm still running the same double-NAT setup and other than an HSI failure, which I detected via the sniffing, I have not had one single WGT624 failure. It's been rock solid with SPI enabled and no port forwarding. Of course it's enjoying a nice quiet ride because it's behind my XP box that is providing NAT and firewall services for it.

The only other thing I changed on my WGT624 which might explain why it's not failing is I went to the port trigger page and increased the timeout to 600 minutes. By default it's set at 20 minutes. Although one would think that this would only apply to specific port triggers that you enable in the port triggering screen, the timeout value may be a general timeout value that applies to the WTG624's routing tables. It may only keep information about PAT for the length of this period. The only thing odd is that doesn't explain the behavior because the Vonage SIP Proxy and the ATA constantly talk to each other. (Every 10 seconds the Vonage's proxy requests a notification from the ATA). That should be enough to keep any PAT relationship alive.

Here are some interesting things about some of the failures I sniffed yesterday surrounded a DHCP NAK. (... this wasn't a WGT624 failure, this was a PAT failure within Windows XP Internet Connection Sharing In this mode, XP is just like a router and if you turn on the firewall feature, it's not too far from being much like the WGT624. However, I don't know if Windows has stateful packet inspection.) When XP received a NAK from my HSI provider's DHCP server (I have HSI with a DHCP IP, not a static IP), it refused to pass outbound packets although inbound was still alive. (Odd, I know). The Vonage SIP proxy was still requesting a NOTIFY from the ATA, the NOTIFY was reaching the ATA, the ATA was resopnding, the response passed through the WGT624 (it was still OK) but XP didn't pass the response out to the internet. This could be a failure of my cable modem more than XP. I suspect the cable modem had taken itself off-line with respect to outbound traffic - since it thought it lost its lease on my IP. However, it was still listening to traffic for my IP and apparently still passing it through to XP. Very odd behavior - to say the least.

Of course, now I'm diagnosing XP NAT/Firewall issues, not WGT624 issues.

I'm still searching for a way to put the WGT624 behind my cable modem and sniff what goes on between them. This is where I think I'll find answers to what's really going down. What I have now, with XP between the cable modem and the WGT624, is fascninating but it's to contrived to allow me to make statements about what might be causing the WGT624 to not work properly with Vonage. If anyone knows how to do this, I'm all eyes (ears).

By the way, I have a WGT624 V2 with the latest firmware and a Cisco ATA-186 from Feb of 2003 (whatever version that might be...)

My primary RTP UDP packets seem to always arrive from Chicago even though I'm in St. Louis. I'm guessing Vonage has a reasonably large contract/arrangement with this firm. I forget who the IP is actually registered to but it isn't Vonage.

Another curious discovery - it seems that Caller ID is resolved in NYC - at least that's what incoming SIP INVITE headers seem to suggest. Not that this is bad but just curious. If you don't live in NYC, brand new numbers might not have caller ID in your area until they've had a chance to propagate to the NYC lookup service that Vonage is using. Again, this is just an assumption based on the SIP INVITE header and how the Caller ID is stored and what looks to be some sort of address identifying where the Caller ID name lookup came from.
