Managed cellular replacement for copper analog lines. The existing fax, alarm dial-out, ATM or POS unit plugs into a For2Fi gateway and gets dial tone over 5G or LTE instead of copper — the equipment and its behaviour stay unchanged.
Fibi sources For2Fi 5G / LTE POTS Line Replacement at no cost to you. Our advisory is funded by the carrier.
We compare For2Fi against 300+ carriers so you know you're getting the best solution for your needs.
Dedicated advisor for the life of your contract — Fibi escalates issues on your behalf so you're never dealing with carrier support alone.
Every analog device on site keeps working exactly as it does today. For2Fi replaces what the line runs over, not what is plugged into it — no new panels, no re-programming, no retraining.
Ordinary VoIP compresses and re-times audio, which is fine for conversation and fatal for machines. Fax, modem and alarm traffic need uncompressed routing with consistent timing. For2Fi preserves signal fidelity end to end rather than optimising for call quality.
Service runs across all major US and Canadian carriers, so the site is matched to whichever network actually performs at that address instead of being locked to one.
The Pro8-Pro gateway carries 8 FXS ports, so a site with a fire panel, elevator phone, fax and dial-backup consolidates onto a single managed connection rather than a stack of copper lines.
Endpoints include battery backup, so life-safety and alarm circuits keep dialling through a mains outage — the scenario in which copper replacements most often disappoint.
Hardware arrives pre-staged, kitted and tested from US facilities, installed by technicians trained on POTS replacement and code compliance, with tier-one troubleshooting and escalation behind it. Line health is monitored remotely and reported before it becomes an incident.
Components can be upgraded independently — LTE to 5G, or a different power arrangement — without replacing the whole deployment. That matters when networks sunset or a carrier leaves a region.
Common questions about 5G / LTE POTS Line Replacement from For2Fi.
More from For2Fi
POTS replacement specifically engineered for fire alarm panels — listed for use under NFPA 72 with supervised dial-out behavior, battery backup for power outages, and AHJ-suitable certification documentation. Customer keeps the existing fire panel.
Cellular replacement for elevator emergency phone lines — interoperates with ASME A17.1 elevator phone requirements, supports the auto-dial and emergency-call patterns elevator phones expect, and includes the battery backup elevator code requires.
POTS replacement for burglar alarm dial-out, central-station signaling, and other security-panel circuits. The existing panel's DTMF and dial behavior continues unchanged — For2Fi replaces only the underlying line, not the panel or the central station.
Fax machines, ATM dial backup, point-of-sale dial backup, and other low-bandwidth analog endpoints kept functional over cellular as the underlying ILEC sunsets copper. Multi-line endpoints available for sites with several legacy lines.
