TL;DR
Failover isn’t a win if your phone system crashes, your VPN disconnects, or your apps force a re-login. Most backup internet setups break key tools by switching IP addresses mid-session. Fidalia solves this by keeping your IP address consistent—even when the connection path changes.
What Usually Breaks During a Failover?
When your primary internet goes down and backup kicks in, here’s what often happens:
- VoIP phones unregister
- VPN tunnels collapse
- Cloud sessions log out
- POS terminals stop syncing
This isn’t a router problem. It’s a network identity problem. Your systems expect to be reachable via a specific IP—and failover changes that IP.
Why Do IP Changes Break Everything?
Every connected service—your phone system, your cloud apps, your payment gateway—associates your session with a specific IP address.
When your IP changes:
- Cloud platforms treat it as a new session
- VPNs drop and often require reauthentication
- Firewalls or security policies block the new connection
- VoIP endpoints must re-register with the PBX
This causes disruption, downtime, and frustration for end users. Even short interruptions can result in:
- Missed calls
- Lost sales
- Interrupted remote sessions
- App crashes and reboots
What You Really Need: IP-Preserving Failover
Fidalia’s OnePort SmartSwitch and UltraSwitch services deliver IP continuity, even when the underlying internet circuit fails.
Here’s how:
- Static-IP tunnels wrap around your connectivity
- Failover happens inside the tunnel, not at your router
- Your external-facing IP stays the same, so sessions persist
- VoIP, VPNs, and cloud apps keep working—no redials, logouts, no reboots
You don’t need to manage DNS records, dynamic routing, or custom firewall rules. We handle all of it.
Real-World Application: 3CX Phone System
Many of our customers use 3CX or hosted VoIP. Without IP continuity:
- Phones drop offline for 2–4 minutes during failover
- Missed inbound calls = missed opportunities
With Fidalia:
- Phones never deregister
- Inbound and outbound calls remain uninterrupted
- Staff don’t even realize failover happened
“We had no idea our fibre line went down—everything just kept working.”

VPN Stability for Remote Teams
Remote users on site-to-site or client VPNs suffer during failover.
A new IP = a broken tunnel = user frustration.
Fidalia’s tunnel-based continuity keeps the VPN link stable across backup paths, even over LTE.
Cloud Apps That Stay Logged In
Imagine having to re-login to 5 different platforms every time the internet flickers.
Slack, Microsoft 365, GSuite, EMRs, POS—most break on IP swap.
Fidalia eliminates these reauth headaches by preserving the connection identity.

Frequently Asked Questions
Why do applications break during failover?
Most failovers result in an IP address change. Many apps, phones, and VPNs use IP addresses for authentication—so they treat the backup connection as new and, most often, unauthorized.
What’s the advantage of a Static IP Tunnel?
It keeps your public IP consistent, even across different internet circuits. This preserves session state and eliminates reauthentication.
Can this work over any connection type?
Yes. OnePort™ tunnels work over LTE, DSL, cable, or fibre—delivering static IP continuity regardless of transport type – Fidalia supports Satellite failover, too, for really remote or unique deployments.
Do I need to manage anything?
No. Fidalia configures and manages everything. We monitor your uptime, handle the tunneling, and support the devices on both sides.
