Use FXO Failover where the protected route is analog and FA100 is the relevant device path.
Failover
OpenVox Failover hardware helps protect voice continuity when an analog or digital line path needs a dedicated fallback device. Start by matching the protected interface type, then review the exact deployment path with OpenVox.
Choose the failover path by protected line type.
FXO Failover is the analog protection path for deployments that use FA100 to preserve a fallback route for PSTN-facing voice continuity.

Map protected line type, device path, fallback role, and deployment review before choosing failover hardware.
Failover selection starts with the protected voice path, then aligns hardware direction, continuity expectations, and deployment validation.
Use the FD series path when the deployment protects digital span or BRI-facing lines.
Frame the product around line-side continuity and the protected voice path.
Review wiring, protected path, and expected behavior as part of deployment design.
Match failover hardware to the protected voice path.
Use the line type as the first decision: FA100 for FXO-oriented analog protection, or FD series paths for E1/T1/BRI continuity requirements.
FXO Failover
Analog failover path for deployments that need FA100-oriented fallback hardware for PSTN-facing line continuity.
- Analog / FXO protection
- FA100 hardware direction
- PSTN-facing fallback route
E1/T1/BRI Failover
Digital failover path for deployments that need FD series protection around E1, T1, or BRI voice lines.
- Digital line protection
- FD140 / FD142 / FD180 / FD182
- E1/T1/BRI continuity
Failover capabilities for voice continuity projects.
Failover hardware gives continuity-sensitive deployments a clearer device path for analog or digital line protection.
FXOAnalog path
Analog Line Protection
Use the FXO Failover path when the protected line environment is analog and FA100 is the right hardware direction.
- Use the FXO Failover path when the protected voice route is analog and FA100 is the relevant hardware direction.
- This path is appropriate for projects that need a clear analog fallback story.

E1/T1Digital path
Digital Line Protection
Use the E1/T1/BRI Failover path when continuity depends on digital span or BRI-facing voice lines.
- Use the E1/T1/BRI Failover path when digital span or BRI-facing continuity is the design driver.
- FD140, FD142, FD180, and FD182 are the model names preserved from the source taxonomy.

HWDedicated device
Continuity-Oriented Hardware
Select dedicated failover hardware where line protection is a deployment requirement rather than a general routing preference.
- The category is positioned around dedicated failover hardware, not general call-routing software.
- Selection should focus on the line type and protected path before detailed device review.
Proof chips
- Line-side protection
- Dedicated failover branch

Deployment Review
Review line type, wiring, and expected fallback behavior before procurement in continuity-sensitive projects.
- Continuity-sensitive projects should align expected behavior with OpenVox before deployment.
- This avoids overstating capabilities that depend on the final line environment.
Proof chips
- Protected line type
- Switchover expectations
Key considerations for failover hardware selection.
Choose failover hardware by protected line type, continuity goal, and the physical voice path it must preserve.
Protected line type
- FXO Failover path for FA100 analog fallback deployments
- E1/T1/BRI Failover path for FD140, FD142, FD180, and FD182
- Selection starts with the protected interface type
- Dedicated failover hardware sits outside ordinary routing features
Continuity design
- Preserve a voice route when the primary path is interrupted
- Match failover hardware to analog or digital line environments
- Protect line-side continuity in branch and service-sensitive deployments
- Review call-path expectations before procurement
Deployment review
- Confirm line type, PBX or gateway role, and physical connection requirements
- Validate expected switchover behavior against the real deployment path
- Use OpenVox support for continuity-sensitive sites
- Keep claims tied to the selected failover device and line environment
Failover Deployment Scenarios
Failover hardware fits projects where voice-line continuity must be protected with a dedicated analog or digital hardware path.
Deployment pattern
Analog PSTN-facing fallback
This scenario keeps the story focused on PSTN-facing analog protection and device-level fallback review.
