Fax, POS & Specialty Line POTS Replacement
Cellular Dial Tone for the Analog Devices Your Business Still Depends On
Fax machines, credit card terminals, gate phones, entry keypads, modems, and specialty analog circuits don't need to be ripped out because of the copper sunset. The POTS Box delivers a reliable, low-cost cellular dial tone so your existing equipment keeps working — without the copper bill.
Analog Devices Are the Forgotten Casualties of Copper Retirement
Life-safety lines get attention. Fax lines, POS terminals, gate phones, and lift-station modems don't — until they stop working. When copper is disconnected, revenue-critical and operational devices go silent with no warning.
- Fax lines carrying HIPAA-sensitive documents suddenly failing
- Credit card / POS terminals unable to process card-not-present fallback
- Gate phones, entry keypads, and callboxes locking residents and staff out
- SCADA modems, lift-station, and utility circuits going offline
- Copper price hikes on lines you use once a week
