Line Replacement for Critical Systems
Your legacy phone lines are being phased out. We replace them with reliable cellular connectivity fast, clean, and without the carrier runarounds.
The Clock Is Already Running on Copper
Carriers aren’t sunsetting copper because it’s the right move for your business. They’re sunsetting it because maintaining aging infrastructure costs them money. Your timeline is not their concern. Ours is.
The FCC has authorized carriers to retire legacy copper infrastructure and AT&T, Verizon, and others are actively sunsetting POTS service across markets nationwide. If your critical systems still run on copper lines, the question isn’t whether you need to transition. It’s whether you do it on your timeline or the carrier’s.
Who This Is For
Built for organizations running critical systems across multiple sites on copper lines that carriers are actively retiring. If your carrier has notified you of a POTS sunset, your line costs are climbing, or your lines are already seeing service gaps, this was built for your situation.
EVO POTS
Why Teams Switch to EVO POTS
Predictable Monthly Costs
Stop paying escalating rates for copper lines that deliver less value every year. EVO POTS gives you fixed, predictable cellular pricing with no surprise carrier charges and no infrastructure overhead.
Future-Proof Your Infrastructure
Low-Disruption Deployment
One Partner Who Owns the Outcome
What Changes When You Make the Switch
Before EVO POTS
- Escalating copper line costs with no end in sight and no clarity on when lines retire
- No visibility into whether critical lines are functioning until something breaks
- Carrier-dependent transition timelines that drag projects out for months
- Systems going offline before anyone on your team knows there’s a problem
- Separate vendors handling different sites with no unified oversight
After EVO POTS
- Fixed, predictable monthly cost per line, no carrier rate surprises
- Real-time monitoring across every critical system and location
- Fast, low-disruption deployment handled entirely by the team
- Proactive alerts before systems go offline, not after
- One partner managing your entire POTS replacement program across every site
POTS Lines Are Going Away
EVO POTS is a fully managed replacement program. You don’t coordinate the transition, manage the carriers, or monitor the lines. POTS lines are disappearing, prices keep climbing, and “just keep it as-is” isn’t an option when those lines support life-safety and critical building systems.
It swaps aging copper lines for reliable LTE & 5G cellular connectivity, giving you a faster path to compliance, lower monthly costs, and real-time visibility you don’t get from traditional providers.
Keep Critical Systems Online While Moving Off Legacy Infrastructure
EVO POTS is designed as a direct cellular replacement for traditional copper POTS lines supporting building and safety infrastructure, so you can modernize without disrupting what’s already running. If it ran on copper, there’s a strong chance it can move to cellular.
- Elevators and emergency phones
- Fire alarm panels
- Security and alarm dialers
- Access control and gate systems
- Fax and legacy analog endpoints
- And more
Managing Multiple Sites? We Built This for That.
Most POTS replacement vendors handle one location at a time. That works for a single building. It doesn’t work for an enterprise managing 10, 50, or 200 locations with critical systems across every one of them.
EVO POTS is built for multi-site enterprise deployments. We centralize visibility across every location, manage number porting where needed, and give you one consolidated view of every critical line in your environment.

Built for Compatibility, Security, and Scale
EVO POTS is purpose-built to replace analog copper lines while supporting the operational realities of enterprise and multi-site environments. Mobility Help Desk manages cellular connectivity as a core competency, which means you’re not just getting a device. You’re getting a team that knows how to keep critical systems connected in the real world.
- Universal compatibility with legacy POTS-dependent equipment
- Integrated security including firewall capabilities and over-the-air updates
- Scalable deployment across multiple locations with number porting support
- Carrier-agnostic LTE & 5G coverage to keep your environment reliable as you grow
Frequently Asked Questions
Is this just a “POTS to VoIP” swap?
No. EVO POTS replaces legacy copper lines with managed LTE & 5G cellular connectivity, not VoIP. That distinction matters for critical systems like fire alarm panels, elevator phones, and security dialers that require reliable, always-on connectivity that VoIP can’t always guarantee.
Will it work with my existing equipment?
In most cases, yes. EVO POTS is designed as a direct replacement with broad compatibility across legacy POTS-dependent systems so your existing equipment keeps working without requiring a full infrastructure overhaul.
How quickly can we move off copper?
Faster than a traditional telecom changeover. Most EVO POTS deployments are completed with minimal disruption and significantly shorter timelines than standard carrier-led transitions, without the back-and-forth that typically drags these projects out.
Do you sell hardware or devices?
No. Mobility Help Desk delivers the managed service and support layer, not standalone hardware. The device required for cellular connectivity is included as part of the managed service; you don’t source it separately.
Gain Visibility and Control Across Every Critical Line
Mobility Help Desk supports EVO POTS with the same approach we bring to every LTE & 5G connectivity program: centralized visibility, proactive monitoring, and predictable outcomes. For organizations managing multiple sites, that means fewer blind spots, fewer emergency tickets, and full confidence that every critical line is functioning exactly as it should.
