Designed to integrate with VoIP, paging, alarms, sensors, locks, and other facility infrastructure, they can serve as outdoor communication endpoints within a broader security and facility management system. In this article, we take a closer look at the two models, examine what sets them apart from more conventional door phones, and explore the applications they can support.

Elevator phones, fire alarm panels, burglar alarm systems, gate entry intercoms, and other life-safety devices were built to run on analog lines. And those lines are going away. For telecom and UC installers and resellers, this situation is both a challenge and a significant opportunity. [Vola Networks](https://www.volanetworks.com/), a U.S.-based high-quality equipment provider, offers POTS (an acronym for plain old telephone service) replacement solutions tailored specifically for managed service providers (MSPs).
