In the fast-changing world of telecommunication, the migration away from traditional copper-line POTS (Plain Old Telephone Service) is no longer a distant forecast—it’s a reality that many Managed Service Providers (MSPs), system integrators, and enterprises are facing today. This shift brings a unique challenge: ensuring the same level of reliability, uptime, and compliance in environments where POTS has been the gold standard for decades.

Vola’s PR12 is designed to meet that challenge head-on. Combining carrier-grade certifications, industry-leading low-power engineering, and a battery system unlike anything else on the market, the PR12 redefines what a mobile VoIP ATA can achieve.

 PR12

Built for Nationwide Carrier Compatibility

One of the first questions MSPs ask about LTE-based POTS replacement devices is: Will it work with my carrier?

With PR12, the answer is an unequivocal yes. It comes fully certified for AT&T, T-Mobile, Verizon, and even FirstNet—ensuring compatibility across all major U.S. networks, as well as their MVNO partners. This level of certification removes guesswork, streamlines deployment approvals, and gives MSPs the freedom to choose the best connectivity option for each site.

Beyond carrier approvals, PR12 meets ETL safety standards and complies with NDAA regulations, making it suitable for government, public safety, and regulated industry use. Whether it’s an elevator emergency phone, an alarm panel in a government building, or a voice line in a healthcare facility, PR12 is already cleared for duty.

TRU24™: True 24-Hour DC-Free Operation

Downtime isn’t an option in critical communications. That’s why PR12 features TRU24™, Vola’s promise of genuine, uninterrupted 24-hour operation without external DC power. While other devices may claim “up to 24 hours” of battery life, their results often come with fine print: reduced functionality, limited voice usage, or standby-only operation. PR12 is different—it’s engineered to deliver full voice service for a complete day under real-world conditions, even during extended power outages.

This capability is not an afterthought; it’s part of the PR12’s DNA. The device is optimized for ultra-low-power standby consumption, allowing it to stretch every milliamp of battery capacity while keeping VoIP services available. The result is peace of mind for MSPs and end-users who can’t afford to go silent.

Small Battery, Big Impact

What truly sets the PR12 apart is how it achieves TRU24™ performance with a remarkably small, field-replaceable battery. Instead of relying on oversized, heavy battery packs that increase cost and limit installation flexibility, PR12 uses a compact battery module designed with energy efficiency in mind.

The advantages are clear:

• Lightweight Installations – Easier mounting in cramped telecom closets, control panels, or elevator shafts.
• Lower Ongoing Costs – Replacement batteries are affordable and quick to swap without specialized tools.
• Sustainable Maintenance – Technicians can carry spares for on-site service, eliminating long downtime due to charging or battery lead times.

This combination of small form factor and long runtime is virtually unmatched in the market. It enables deployments in locations where space, ventilation, or access is limited—without sacrificing reliability.

Optimized for MSP Scalability

For MSPs, the PR12 is more than a device—it’s part of an ecosystem. Integrated with VolaCloud, it supports bulk provisioning, remote diagnostics, firmware management, and real-time battery health monitoring. This means fewer truck rolls, faster deployment, and the ability to maintain SLAs even in geographically dispersed environments. A typical PR12 deployment looks like this:

1. Install the device and insert the SIM card of choice (primary and backup SIMs supported).
2. Activate the line via your UC platform using auto-provisioning.
3. Monitor status and battery performance remotely via VolaCloud.

The result is a “set-and-forget” POTS replacement solution that’s both carrier-flexible and technician-friendly.

Where PR12 Makes the Difference

The PR12 thrives in mission-critical applications such as:

• Elevator emergency phones – Comply with safety codes without dependence on copper lines.
• Security and fire alarm panels – Maintain connectivity during prolonged power outages.
• Healthcare and assisted living – Ensure nurse call systems remain active when grid power fails.
• Remote industrial sites – Provide reliable voice lines where wired connectivity isn’t viable.

In each case, the combination of TRU24™ battery backup, LTE flexibility, and compliance certifications means the PR12 can be deployed quickly and confidently.

The Future of POTS Replacement is Here

The shift away from POTS is accelerating, and with it comes the need for solutions that are proven, efficient, and field-ready. PR12 is purpose-built for this moment. It’s small but powerful, low-power but high-availability, and certified for the networks and environments that matter most.

For MSPs, PR12 represents more than just a hardware upgrade—it’s a competitive advantage. It enables faster go-to-market timelines, minimizes installation complexity, and ensures long-term service continuity. In a marketplace crowded with generic ATAs and oversized battery boxes, PR12 stands alone as the only device that delivers true 24-hour DC-free voice service in such a compact, replaceable-battery design.
