Keep fax, POS and analog devices
working without disruption.
Staff keep using familiar analog devices. Redstone preserves the local interface and provides a controlled path to the destination service.
Why Fax, POS and Special Analog Devices Need POTS Replacement
Many business workflows still rely on analog devices. When carriers retire copper lines, the device interface and the calling path must both be preserved.
Copper Lines Being Retired
Fax machines, POS terminals, modems and other analog devices lose their connection path when carriers retire copper lines.
Staff Use Familiar Devices
Staff keep using the same analog devices they already know. No new training, no workflow disruption.
Flexible Connectivity
Redstone preserves the local interface and provides a controlled path to the destination service via PSTN or SIP.
How the Redstone Solution Works
The analog device connects to a Redstone gateway via FXS. The gateway provides a controlled path to the remote service via PSTN or SIP.
What Must Be Preserved
Fax, POS and special analog device workflows have specific requirements that must continue to work after POTS replacement.
Real-World Scenario
See how the Redstone solution applies in a real deployment environment.
Designed for Your Environment
The Redstone gateway integrates seamlessly with your existing infrastructure. No device replacement, no workflow change — just a modernized connection path with reliable backup.
A Lower-Disruption Alternative
The right path depends on the device type, workflow requirements, and the destination service.
Complete Device Replacement
Rip-and-replace approach
- Replace all fax machines and POS terminals
- New equipment procurement
- Staff retraining on new devices
- Workflow disruption during transition
- Higher upfront investment
Redstone POTS Replacement
Keep the device. Replace the line.
- Use existing fax, POS and analog devices
- No device modification needed
- Controlled path: PSTN or SIP
- No staff retraining required
- Lower cost, faster deployment
Validate the Device Workflow
Acceptance should confirm the analog device can complete its intended workflow through the new connection path.
The Continuous Value Path
POTS replacement is only the first step. The same platform can later support digital fax, cloud POS, and centralized device management.
Endpoint Reuse
Retain existing analog devices
Replace only the connection path
Platform Upgrade
Connect IP communications
Centralized device management
Digital Services
Cloud fax and POS
Device analytics and reporting
