A hosted PBX (Private Branch Exchange) is a telephone switching system that’s accessible over a network in the cloud. A hosted PBX is cloud-based, which means that you can make your employee’s phone all from your web browser or an app. Phone lines and calls happen entirely over the internet, cutting down on hardware and labor costs. Plus, it allows your employees to work remotely and use their business phone number from anywhere, rather than being tied to a landline in the office.
