Cloud PBX is a hosted or virtual PBX system that provides phone system capabilities without expensive equipment. It allows businesses to run efficiently through flexible and cost-effective communications that keep employees and clients connected. Some benefits of switching to cloud PBX include lower costs as there are no maintenance fees or expensive setups and businesses only pay for what they use. It is also perfect for small businesses as it provides features normally only available to large companies at affordable prices and scales easily from a few to hundreds of extensions across multiple sites. Cloud PBX also improves productivity by allowing employees to stay connected wherever they are and creates an office-like environment even for remote or virtual businesses.
