Multiple IP addresses
Add IPv4s, pin trunks to specific IPs, and whitelist agent home offices.
Each VICIfast server comes with one IPv4 + one IPv6 /64. You can add more IPv4 addresses from the dashboard at your server → IP Addresses; Hetzner attaches them, we reload the firewall, you see them in the dashboard within a minute.
Per-trunk pinning
Some carriers (Twilio Elastic SIP, Bandwidth) require a distinct source IP per account. After adding extra IPs, pin a specific trunk to one of them in the Manage Trunks form. The PJSIP transport binds the trunk's outgoing traffic to that IP.
Firewall whitelist
Use the same IP list to whitelist agent home offices, your office VPN, or partner systems via the firewall section of the dashboard. Combine with the agent self-serve portal (firewall.<your-brand>.com) so agents can whitelist their own IP without a ticket.
Cost
Additional IPv4s are billed at Hetzner's price, passed through with no markup. The first IPv4 is included with the server.
