For decades, the telecom industry has depended on bulky backup power solutions to keep POTS replacement devices online during outages. These systems often relied on oversized, heavy battery packs that raised costs and limited installation flexibility. MSPs deploying at scale struggled with high logistics expenses, complex maintenance, and the challenge of installing in tight spaces such as elevator shafts or utility closets.

The PR12 introduces a breakthrough. Powered by its TRU24™ design, the PR12 delivers up to 24 hours of standby with just a single 18650 battery cell. Rather than increasing size and weight, the PR12 achieves endurance through engineering efficiency and smart low-power design.

When disconnected from DC power, PR12 shifts into a deep sleep mode. WAN and LAN ports power down, while SIP and VoLTE modules stay active, ready to respond. The device wakes every 30 seconds for self-checks and every 300 seconds to sync with VolaCloud. Importantly, any incoming SIP or VoLTE call wakes the device instantly, ensuring uninterrupted emergency communications.

In lab testing, PR12 reached up to 26 hours of standby when paired with low-consumption analog phones, outperforming market peers. For MSPs, the benefits are clear:

• Lightweight installs in constrained spaces.
• Affordable maintenance with easy-to-swap batteries.
• Sustainable field service, since technicians can carry multiple spares.

The result is not just longer uptime, but a competitive edge. With PR12, MSPs can deliver reliable, scalable, and cost-effective POTS replacement solutions. Truly, small battery, big impact is the new benchmark.
