Setting up skype sip gateway with trixbox

Hi,

I have skype sip gateway running on vasuntu and am using that as my gateway between trixbox and skype.

I have setup the trunk and everything else, but when i dial to the skype accounts i keep getting a "user not found" error from skype.

I live in barbados and we have to pay through the nose for 1800 and 1888 numbers. So i setup an outgoing route to direct these numbers to the skype trunk and im hoping to push these toll free numbers through skype.

If anyone has any advice on how to get this to work, or if its even possible, that would be great.

Thanks.
