A virtual phone is a telephone service that routes calls to a specific phone number or numbers to another telephone number or numbers, either landline or mobile, using the internet. It allows users to have a phone number that is not tied to a specific physical location or phone line, allowing them to make and receive calls from anywhere with an internet connection.

Virtual phone services are often used by businesses as a cost-effective alternative to traditional phone systems, as they do not require the purchase of hardware or the installation of phone lines. They also offer a range of features, such as call forwarding, voicemail, and auto-attendant, that can help improve communication and customer service.
