This is because the bartonrail domain is set up to embed your e-voice website (i.e., as a frameset) instead of pointing directly to the e-voice server.

You should remove the redirect configuration (at names.co.uk where you registered the domain) and instead configure it as per the instructions for Custom Domains.

i.e., you need to add the domain name to the Site Domain settings of your Voice site, and then set up an appropriate A record in the DNS configuration of your domain.

From then on, everyone (you and visitors and google et al) will always use your custom domain name, as the e-voice URL will effectively be hidden. (The e-voice URL will still work, but will redirect to the custom domain name)
