pointing a wrtp54g linksys router at the Voipo platform and getting dial tone

i have the line up as a full service line i also configured the phone# with the mac id for the device, where i get confused is the voice tab on the linksys router page where it gives you user password space to fill is this the phone # off the sip credencials or the pass word off the sip credentials then what to put in the main dns spot? i think it would be the voipwelcome of the sip credentials but i maybe wrong then last what goes in the secondary dns ? Can someone please help?

User= phone number

line 1 and/or line 2 page pass= password from the sip credentials page

user password on the system page is to protect the internal voice pages.

dns= your favorite dns server 8.8.8.8 will work

proxy= sip.voipwelcome.com or whatever they give you...
