A virtual phone system basically uses virtual phone numbers and Voice over IP (VoIP) to transmit calls over the internet.
In simple terms, when you make a phone call using VoIP, the analog audio signal is converted into a digital signal. This digital voice data is then sent to the virtual phone service provider using your internet, and then the message is routed to your customer’s phone.
It’s 100% in the cloud and works with your existing smartphone, laptop or tablet. With virtual phones, you can make and receive calls, add phone numbers and configure your virtual office phone system for business without relying on IT staff.
