Our vpbx management portal SPP (Service Provider Portal) allows you to use Dynamic DNS; SPP can automatically create and update DNS records for your vpbxes using Dynamic DNS. For example, SPP can automatically create vpbxname.yourcompany.axeos.cloud when you create the vpbx in SPP.
If you also support DDNS on your side and send us the address of your nameserver, send TSIG key type, name and value and the domain to be used then we can automate the creation of subdomains for you.
Alternative you could point your domain to our nameservers and we can take care of the rest. Either way contact us through our contact form.
