If your business still runs on old-school copper phone lines, chances are you don’t think about them often — until they stop working. Fire alarms, elevators, fax machines, security panels, POS terminals: all of it can quietly depend on plain old telephone service (POTS) that’s being phased out across the country. That’s why we’re excited to announce our new partnership with Granite and the launch of Granite EPIK, a purpose-built solution for POTS replacement.
The Problem With Aging Copper
POTS lines have powered critical business infrastructure for decades, but the carriers that maintain that copper network are retiring it. For many businesses, this isn’t a future problem — it’s already here. And because these lines often support life-safety systems like fire alarms and elevator phones, letting them lapse isn’t an option. The challenge is that most POTS replacement projects sound more complicated than they need to be.
Meet Granite EPIK
Granite EPIK is a compact, reliable device built specifically to take over where copper leaves off. It runs on 4G LTE with a 24-hour battery backup, meets 2026 fire code requirements, and is approved by both FDNY and Cal Fire. Just as important, it’s compatible with the equipment your business already has — fire alarms, elevators, fax lines, security panels, and POS/ATM systems all connect the same way they always have. Nothing on your end changes except the technology quietly working behind the scenes.
Simple, Transparent Pricing
We built this offer to be as painless as the install itself: $60 per line, per month, all in. That includes the equipment, the site survey, installation, and the SIM — no hidden fees, no surprise line items later.
The POTS Solution You Need, Paired With the Support You Love
Here’s what makes this partnership different: Granite handles the technology, and twenty7 Tech stays your point of contact. From the initial site assessment through installation and ongoing monitoring, we’re managing the process on your behalf. You get a modern, compliant replacement for your aging copper lines without having to manage a new vendor relationship or learn a new system.
Why Now
POTS replacement is quickly becoming a compliance issue as much as a technology one. If your business — or any client, tenant, or account you manage — still has analog lines running fire, elevator, or security equipment, the clock is already ticking. The good news is that with Granite EPIK, this is one of the easiest upgrades you’ll make all year: no rip-and-replace of your existing equipment, no disruption to daily operations, and no guesswork on pricing.
Let’s Talk
If you’re not sure whether this affects you or your customers, it starts with one simple question: do you still have any analog lines running your alarms or elevators? If the answer is yes, we’d love to walk you through what a switch to Granite EPIK would look like.
