Cloud-based voice over internet protocol (VoIP) services provide small businesses a great deal of flexibility. Whether you have remote workers, are constantly on the run, or just want to save money on hardware, a cloud-based VoIP system is likely your best option. Hosted in the cloud and run by the business phone provider, cloud-based VoIP services can be accessed from cell phones and computers via a mobile or desktop app and are ready to go once you install them on your device.
