The document introduces a hosted PBX phone system as an alternative to a traditional on-site PBX system. A hosted PBX offers significant cost savings of around 40% compared to a traditional system for a 19-seat office. It provides more features than a traditional PBX without requiring on-site equipment or space. The hosted PBX system is maintained off-site by the provider and allows adding new features immediately. It also scales easily as a business grows without needing to add new phone lines or rewire.
