Here is my setup...Cable>Modem>Dlink WBR2310 Router/Firewall>Motorola 2142 Vonage Adapter.

I have poor audio quality. It is very choppy however, the people on the other end say they can hear me fine.....After doing some research on this site, I have discovered that it could be that my phone adapter is getting shortchanged on packets because of my SPI firewall....That makes perfectly good sense....My firewall settings can be tweaked a little bit, I am just not sure which ones...I would assume in the "Application Rules" settings I could tweak the ports that traffic is flowing on..??????..There are options for a "Trigger Port" and a "Firewall Port" and "TCP" or "UDP" types of traffic. Is this where I can tweak this, or in the "Port Forwarding" section which looks identical in terms of settings?

I believe my connection to the internet is ok, I have done lots of tests and it seems to be fine.....I thought that troubleshooting the firewall would be the best place to start since if it can be tweaked, I should do that first.

You're probably right about the firewall, and I can't advise you on that. However, the first thing I would do is temporarily remove the router and see if that fixes the phone problem. If it does, put the router back in but with the firewall totally disabled. If things are still good, then work the firewall issue. Otherwise, go where the evidence leads.

By the way, where is your computer plugged in?

My PC is plugged into a switch behind the Dlink router.....i.e......

Cable>Modem>DLink Router>Vonage Adapter

Hanging off the Dlink is also another switch which has a couple of pc's and access points
