In the previous article we discussed why network reliability is crucial for UC solutions. This time I will explain why PoE switches are important to grant power continuity of the phone service to match those of traditional PSTN systems.
When switching from a legacy phone system to a modern UC server, many things are taken for granted by the buyer. For example, that the system will also work in case of emergency situations, like a power outage.
Home analog phones connected directly to a local exchange usually work in the case of power outages, as the local exchange uses a UPS system. Legacy PBXs worked in a similar way, either embedding a battery or relying on a separate UPS system.
