Setting up multiple sites on one custom domain

The steps you need to follow for each custom domain:

1) Add "example.yourdomain.com" (or "example.com", depending on what you want) as a custom domain to your Phonesites > Website > Config > Custom Domain section

2) Add an A Name DNS record on that subdomain (example.yourdomain.com) from your hosting / dns management company that points to our IP: 159.89.244.198
