legacy telephony systems

Legacy telephony systems are the traditional phone networks that have been used for decades to handle voice communication. They typically rely on Analog or Early Digital technology, such as landlines connected through copper wires or early digital switches. These systems are reliable but often less flexible, costlier to maintain, and limited in features compared to modern solutions like VoIP (Voice over Internet Protocol). As technology advances, many organizations are transitioning to newer, internet-based systems that offer greater scalability, enhanced features, and reduced costs, but legacy systems may still be in use in some workplaces due to their established infrastructure.
