EnGenius DuraFon Pro PIA Phone System Kit
The EnGenius DuraFon Pro PIA Phone System
Your warehouse supervisor steps out onto the loading dock, your farm foreman drives to the far fence line, or your dealership's lot attendant walks to the back row — and a normal cordless phone drops the call somewhere around the parking lot. The EnGenius DuraFon Pro PIA Phone System Kit is built for exactly the distance that breaks every other cordless system: up to 12 floors of building penetration, 250,000 square feet of warehouse or retail floor, or 3,000 acres of open land from a single base unit.
It's also not just a phone. Every handset doubles as a two-way radio, so your team can intercom handset-to-handset or broadcast to the whole group without tying up a phone line at all.
Why the EnGenius DuraFon Pro PIA phone system covers so much ground
Most cordless phones — including DECT systems — top out well under a few hundred feet once walls and steel shelving get involved. The DuraFon Pro PIA runs on 900 MHz (902–928 MHz) frequency-hopping spread spectrum instead, a lower, more penetrating frequency built specifically to punch through concrete, metal racking, and multiple floors without losing the call.
Scales far past the 4 handsets in this kit
This kit ships with one base and 4 handsets, but the base unit itself supports up to 90 handsets, and the system expands to 8 base units for up to 32 total phone lines. A single install can grow from a 4-person crew to a full warehouse floor without swapping out the core system — you're just adding handsets and, if needed, additional bases.
Phone system and 2-way radio in one handset
Every DuraFon Pro handset works two ways. As a phone, it registers to the base and makes and receives calls through whatever line the base is connected to — PBX extension, VoIP analog port, or a standard PSTN/POTS line. As a radio, it talks directly to other DuraFon Pro handsets over private intercom or group broadcast, completely independent of the base — so staff can reach each other even if they're both out of range of the building.
Talk time and durability
Each handset runs on a hot-swappable Li-Ion battery pack — this kit includes two batteries per handset, so a spent one goes straight into the charging cradle while the backup keeps the shift moving. The handsets are built for the environment they're sold into: drop-tested repeatedly onto concrete and rated to survive daily use in a warehouse or manufacturing floor, not a desk.
Call management on the base and handset
The base unit includes an auto attendant and speakerphone, and each handset has a 4-line LCD display for call logs and caller ID where the connected line supports it. A dedicated broadcast button on every handset triggers push-to-talk paging to the group without dialing anything.
For a business spread across a large floor plan, a farm, or a multi-building lot, the EnGenius DuraFon Pro PIA phone system replaces a phone, a 2-way radio, and a paging system with one device your team already knows how to use.

Software: The DuraFon Pro system has no VoIP client or app dependency — it connects at the line level, so it works the same whether the line behind it is a traditional phone line, a PBX extension, or a VoIP provider's analog gateway port.
Hardware: The base connects to any analog telephone port — a PBX analog extension, an FXS port on a VoIP gateway, or a standard PSTN/POTS line. No special wiring or network configuration is required beyond that single analog connection.
Platforms: Because it operates independently of Wi-Fi and VoIP signaling, the DuraFon Pro isn't tied to a specific UC platform — it works behind whatever phone system already terminates in an analog port, including most legacy PBX systems.
