Re: [Config] Catalyst 3550 config to connect to Cisco 525G2 phon So you have a 3550 connected to your current DSL or cable modem?
That device won't care what the 3550 is doing so create as many VLAN's as you want. All you have to do is point a default route from the 3550 to the modem. Remember to create appropriate SVI's for each VLAN and enable IP routing on the 3550.
I took a quick look at the 8x8 site but I didn't find what protocol they use for call signalling. I know I shouldn't assume but I expect it's SIP. Does your phone have SIP firmware? Alternatively does the 8x8 set up have some way of supporting skinny?
Once we can answer those questions we may be able to move on to a discussion about QoS!
