Use your own domain
Run your dialer on your own address, like dialer.yourcompany.com: the two DNS records, at order time or later, plus the branded firewall page.

Your dialer can live at your own web address, like dialer.yourcompany.com, instead of a VICIfast address. Agents see your brand in the address bar, and we issue and renew the security certificate (the padlock) for you. You can choose your own domain when you order, or move a running server onto it later. Most of the work is adding two records at your DNS provider.
What you need
- Any plan: your own domain is included on every plan, the free trial too.
- A domain you own, and a login to its DNS settings (Cloudflare, GoDaddy, Namecheap or similar). Step-by-step for your provider: Add DNS records at your domain provider.
- The address you want, as a subdomain such as dialer.yourcompany.com. Its first word ("dialer") must not already be used by another VICIfast customer.
Step 1: Choose your own domain when you order
- On the order page, go to the Region & domain step.
- Under Domain, click Your own domain (Included · add one CNAME).
- In Your fully-qualified domain, type your address, for example dialer.yourcompany.com.
- The page shows Add this CNAME at your DNS provider with the exact record.

Step 2: Add the CNAME and verify it
- At your DNS provider, add a record of type CNAME. Name: _acme-challenge. followed by your address. Value: the long value on screen. TTL: Auto (or 300s).
- Save it, come back and click Verify CNAME.
- When it works you see "Using your own domain:" and your address. Carry on with the order and pay.
This record lets us issue and renew your certificate without ever needing your DNS login. If it fails, the message says what to fix. DNS usually updates within seconds, but some providers take a few minutes: wait a minute and click Verify CNAME again.
Step 3: Point your address at the server
- After payment, open the server from My Servers. An amber box says Point your DNS at this server.
- At your DNS provider, add an A record. Name: your address. Value: the IP address shown (use Copy). TTL: 300.
- Once the record is live, usually within a minute, the setup carries on by itself.
Step 4: Move a running server to your own domain
- Open your server from My Servers.
- In the tools strip, click Configurations, then Hostname.
- In New hostname, type your address and click Check hostname.
- The panel lists two records to add at your DNS provider: an A record pointing your address at the server, and the _acme-challenge CNAME. Each value has a copy button. Use a low TTL (300s).
- Click Rename server, then Yes, rename it.
The old address stops working, so update bookmarks, agent links and anything that calls your server's API. Renaming to a different VICIfast address works on every plan and needs no DNS records.
Step 5: Put the agent firewall page on your domain (optional)
Agents approve their own internet address on a firewall page. On a server running on your own domain, that page can move to firewall. plus your domain, for example firewall.yourcompany.com.
- Click the Firewall chip on the server page.
- Find the card Branded firewall portal with Action needed.
- Add every record the card lists at your DNS provider, then click Re-check.
- When the card shows Live (usually a few minutes), the portal link at the top switches to your domain. Send agents the new link.
If something goes wrong
Frequently asked
- The first word of your address is taken. Pick another first word, for example pbx.yourcompany.com instead of dialer.yourcompany.com.
- The _acme-challenge record points somewhere else. Change its value to the one on screen and click Verify CNAME again.
- Give your DNS provider a minute or two, then try again. Checks are limited to about 30 a minute, so waiting works better than clicking repeatedly.
- Your plan doesn't include your own domain. Change plan, or rename to another VICIfast address instead.
- Check the A record points at the exact IP in the amber box, and that no proxy or CDN is switched on for it.
