VOIP over SRW208P not working

I have a Linksys SRW208P switch I bought and I am trying to get my polycom 330 to work over it via POE.

The phone powers on, grabs an ip address from my dhcp. However, the phone does not register with my asterisk box.

Any ideas? I do not have much experience configuring layer 2 or 3 switches.

Also, and this is more of a rant then a question. I can not configure this switch via the web interface. The damn thing needs IE and active X to be turned on. Who in their right mind is running IE with Active X enabled. Who is running IE at all for that matter?

BTW... My POE is working correctly. And just to give more info... My subnet mask is 255.255.255.0 on the switch with an ip of 10.0.0.210 and the router is 10.0.0.1

Not sure if that is relevant or not. I am looking at a subnet mask calculator right now trying to figure this whole thing out.

Also, computers behind the switch can see the net just fine.

I dont mean to be a annoyance. I just want to update the question as I am working on this to try to fix it.

The switch seems to be filtering by port. I can get out on port 80 (browse websites) but I can not use vnc on port 5900. I also can not use my sip phone, which is the real problem. Sip works over port 5060 and a couple others.

Okay, so I was wrong. The ports are being passed. For some reason Bonjour does not work though which makes me think it is a subnet mask issue again. I understood subnet masks for a day once. Then I went to bed and woke up not understanding them. I guess I am just going to try every subnet mask till my sip phone works. :P

Figured it out... With an out of the box configuration, in order for a sip phone to work you must go to (through the webview) the multicast tab, then bridge multicast forward all, then set all of the ethernet radio buttons to static from the default of none. Leave the lag ones as is.
